A New Paradigm for Cruising

Tech Talk

Following is where you’ll find Steve & Linda’s more technical articles. If you’re looking for info on the nuts and bolts of cruising, this is the section for you!

A Flat Screen Monitor Which Really Dims

In the past we’ve opted for the standard monitors, and dealt with the excessive brightness at night with a plastic “lens” over the screen to help protect our night vision. Now we’ve found something better. Last week we tested a 17″ Samsung model 740 BX to display our SONAR and radar data. We expected the wide viewing angles and sharp images. But what surprised us the most was the excellent dimming capability. And all of this for $200.

Depth Recorders for Interpreting Bottom Type

When we started looking at the electronics specifications for Wind Horse, we considered adding a depth finder with a bottom echo display, if it would also help us tell the difference in bottom conditions. Our reasoning was that it was worth having this gear in areas where it was hard to find a nice spot in which the anchor could dig in – if it really worked. So we checked with several friends that had powerful depth sounders and they all told us the same thing, that they could not consistently tell one type of bottom from another. As a result we stayed with a simple digital read out – no moving display. This is the same approach as we’ve used for the last 20+ years.

One of the benefits of the Furuno CH 270 sonar we’ve just installed is that when the transponder is aimed down (vertical) it works as a very high-end depth sounder. During recent testing, with Furuno sonar guru Steve Bradburn aboard, we asked about interpreting bottom condition from the visual echo trace. Read the rest »

Modern Food Packaging & Long-Term Storage

Like most of the cruisers we know, the crew in charge of marketing for Wind Horse tends to over-buy food when we’re getting ready to head out. We’ve found it is best to stock up when we can acquire the foods we like at reasonable prices. New Zealand is a great place for this, especially if one is heading to the tropics where supplies may be limited and will almost certainly be more costly. Read the rest »

Aqualarm

We’ve had Aqualarm ( www.aqualarm.net ) products on our boats going back to the early 1970s. Catching up on our mail recently we noticed a new catalog with some interesting products which we thought might be of interest. Aqualarm makes a range of engine, bilge, and intrusion alarms, much of which works well for retrofit.

Alarm Systems On Board

Over the years we’ve looked at alarm systems for various clients, and even installed a few. However, the results have been less than stellar, often involving so many false alarms that the systems were typically not used. We decided to give this subject another look for Wind Horse. After all, there has been a lot of progress in other electronics areas, so why not in alarms? Read the rest »

Maintaining the Outboard Motor

Propellor Engineering

Propeller engineering involves a combination of science, gut instinct based on real world experience, and trial and error. Regardless of the project, the latter part of this equation is always present – even on military vessels, when billions are spent to get it right, you cannot get away from trial and error. With Wind Horse, we’re just on our second set of props, which have been slightly modified from their original design. By adding a slight amount of cupping we have gotten close to where we want to be. (Adding a trailing edge cup to a propeller works like a flap on the back edge of an airplane wing. The cup/flap increases the lift of the foil.) Read the rest »

Engine Vibration and Noise

With 16,000 miles now on Wind Horse we’ve zeroed in on a couple of things that we want to fine tune. One of these is the level of engine noise and/or vibration. Mind you, at our cruising speed of 1900 RPM/11.3 knots this is just 57 dB in the saloon/bridge area, so the noise level is already very low. But when you are passaging for thousands of miles, what would be considered almost silent on most boats can become bothersome. As we are in Ventura, California, we called our old friends Dale and Steve who own and run Ventura Harbor Boat Yard. Steve came down with his yard foreman, Tom, and they gave the exhaust system a quick look. Read the rest »

BGAN + FollowMeTV: The Ultimate Communication Tool?

BGAN is a relatively new INMARSAT service with much higher speeds and smaller antenna needs than what has been available in the past. The service is new, but from what we hear it is working well so far. The rub for cruising sailors is the lack of an antenna system to track the satellite, and – when these become available – the cost. We were wondering if the FollowMeTV single axis tracker, like we use for our Direct TV reception, would work. We talked to the guys at BGAN about this and it sounded propitious, so we got Ray Barnard at FollowMeTV to chat with BGAN – tech-to-tech, so to speak. Read the rest »

Favorite Tools, Part 1

Over the years we’ve accumulated an assortment of specialty tools. Most of these are rarely used, but when required, they have been essential for getting maintenance projects completed expeditiously. Whether you carry these or not depends on your fetish for tools, how much space you have for storage of rarely used gear, and where you’ll be cruising.

Drogue Testing

For many years we’ve been students of the concept of using drogues in heavy weather, or for holding station when disabled. We did extensive research on this subject – interviewing dozens of users – when writing Surviving the Storm. But in our own cruising experience we never had conditions where we thought the use of such devices was a better option than keeping the boat up to speed. With Wind Horse, the situation is potentially different. So, we’ve carried a Fiorentino parachute anchor, Galerider, and Jordan Series Drogue. We’ve looked at the rigging of these, discussed how to use them, but until recently have not found the time to actually get this gear into the water (our strong suggestion to you, if you carry any of this equipment, is to become familiar with it before heading offshore).

Binoculars Revisited

A few months ago we did a short report on the three types of binoculars we have aboard Wind Horse. Having 5000 miles more experience with them since that report, we thought we’d update you on our feelings. First, the image stabilized Canon 15 x 50s. These are excellent in good light and smooth water. We can use them in light chop, but anything that is at all bouncy makes it very difficult to find and then hold an image centered.

Aluminum Paint Specification

Aluminum boats are wonderful. The only problem area is with painting. It is not an easy material to get paint to stay on without problems. On the other hand, it is the only material which can be left bare, and that is a huge plus. We like the look, and the lack of maintenance. And if someone messes up a docking maneuver, we ignore the scratches – or if we’re feeling ambitious, polish them out with ScotchBrite pads. Of course you still have to do something with the part of the boat that is in the water. What is done below the waterline is quite different than above. The system used needs to tie to the bottom paint being used. In the past we’ve always used TBTF bottom paint, but this is no longer available. Read the rest »

Outboard Motor: Engine Size vs. Fuel Consumption

For the past 18 years we have had 30HP Yamaha outboards on our dinghies. The 30 was chosen for several reasons. First, we like to water ski and this is the smallest engine with which we can drag start on a slalom ski (tricky, but it can be done). The second reason is that this is plenty of power to push the big boat around should we need it in a tight harbor with lots of wind blowing. In effect, this serves as our “thruster”. Read the rest »

Poly V-Belt After 1500 Hours

Powerful DC engine-mounted alternators require large doses of horsepower to produce their electricity. This is normally transmitted via V-belts, from the power take off (PTO) pulley on the front of the engine crankshaft to a pulley on the alternator. Traditional V-belts have a hard time dealing with really big alternators, and require careful alignment, heavy duty tensioning hardware, and early replacement (for a lot more on this subject, see Offshore Cruising Encyclopedia). The John Deere diesels which are aboard Wind Horse use a new (to us) type of drive belt off their PTOs. These are called Poly-V belts, and are ribbon-like in appearance. They are reported to be more forgiving than traditional V-belt designs, but we took a wait-and-see attitude. Read the rest »

Gig Harbor Rowing Dinghy

We’ve carried a variation of the Catalina Wherry, a 14-foot (4.3m) rowing dinghy, on all our cruising boats going back 30 years. Even Wind Horse had a used version which we picked up in New Zealand prior to leaving. However, we’ve been hankering for something a little more sophisticated, and have been looking at rowing dinghies with sliding seats. A sliding seat allows the rower to use both arms and legs when working the oars. After arriving in the Northwest we started seeing a lot of sliding seat dinghies built by Gig Harbor Yachts, of Gig Harbor, Washington. There were a number of things about their 14-foot model which appealed to us. Its sloop would fill the need to daysail. And it allows the sliding seat to be fixed in an aft position, and then rowed double. We contacted the factory in June and were told four months for delivery. That was too long as we’d be a 1000 miles south by then. Read the rest »

Binoculars

Thirty years ago, when we were looking for binoculars, we ended up at a discount sporting goods store and bought a pair of 7×50 land-style binoculars. They cost us 10% of the fancy marine binoculars ($35 for a display model), and worked all the way around the world. We would have liked some high-quality glasses, but these were almost as good, and we could not justify the hit on the cruising budget for the marginal gain of the highest-quality pair. At the end of our circumnavigation there was some fogging from moisture, but they still functioned. Twenty years ago, we were given a pair of Fujinon 7x50s. These had wonderful optical properties – at night and during the day – and they were still working well when they went to Beowulf‘s new owner as a part of her equipment after 17 years of rough service.

Dinghy Set Up

Exploring in cold country with the dinghy introduces an additional set of risks which call for extra emergency preparation. We’re usually off by ourselves, and it is doubtful that anyone would miss us or hear a call for help. So we need to be prepared for a wider range of risk factors than in warmer climes.

Digital Chart Risks

Electronic charting systems are a step up from the olden days of pencil, dividers, and paper. Used correctly, they reduce workload and offer a higher factor of safety, especially in difficult conditions. However, there are numerous risk factors associated with using electronic charts, so we feel it is wise to maintain a healthy dose of skepticism and double-check the results. Read the rest »

Furuno Radar Software Update

One of the cool things about our Furuno 2117 black box radar is that the hardware is secondary to the software. The hardware is basic, robust, and powerful. It is the software, that controls the various functions like signal processing and scanner, which gets out of date. The fact that the software can be easily upgraded is one of the reasons we decided to go with the 2117 in the first place. Read the rest »

Dealing with Engine Blow-By

When diesel engines operate, there is a small amount of pressure which slips by the piston rings. This pressure gets into the block and rocker arm cover of the engine and has to be relieved in some form. Typically a vent hose is attached to the rocker cover, and maybe one from the crank case. The pressurized air which is expelled carries with it a fine mist of oil. After a while everything in the engine room is covered with oil. Read the rest »

Engine Oil Leaks

Oil leaks and engines seem to have a symbiotic relationship. The oil leaks provide the engine a chance to vent its frustration at being abused, while the engine allows the oil to escape and spread itself out in the world at large (or at least in your bilge). Most of the time these leaks are tiny, and difficult to stop. Some years ago we had such a situation on Beowulf. It wasn’t until we ran into a diesel mechanic in Maine that we learned how to deal with these small leaks. Read the rest »

Laundry While Cruising

Image To do laundry in the Banks Islands, just south of the Solomons, all you need are some rocks, a source of water, and plenty of time. I have to admit that I’m a laundry junky. I find it very satisfying to wash, dry and iron. It’s one task that has a beginning, middle and finished product in a relatively short period of time. What a difference 30 years makes! Looking back to cruising on Intermezzo in 1976, we didn’t even consider what it was going to be like cruising with two small children without any laundry facilities. We had enough on our plate converting a racing boat to a cruising boat for a family of four. We took out the second head and made a pantry, took the forepeak bunks and made an athwartship double bunk for the master stateroom, but didn’t think much about how we would handle laundry. When we went cruising, I paid to store our relatively new home washing machine and dryer for seven years – which was silly, as it would have been much smarter to sell them and buy new ones later on.

Prop Zincs vs. Hull Zincs

When we first put Wind Horse in the water, we did not fit hull zincs. We were relying on the prop zincs, and zincs hung from the rail at anchor for galvanic protection. The zincs were being eaten too fast so we decided to pay the drag penalty (small) and weld plates with threaded holes to which we could bolt large zincs to the keel and near the props (four in total).

Storm Covers for the Hatches

We’ve been using the same detail for hatch storm covers for years. This includes a tight-fitting cover, some form of lip for the cover to fit over or around, and on Wind Horse, a new feature. In the photo below you will see a series of lashings over the cover itself. These are to help hold the cover in place in truly awful conditions. Although we’ve never had problems with covers coming off in the past, this detail is more suited to the type of weather we may encounter with the new boat. Read the rest »

RTV Silicone Gasket Material

Some years ago we were introduced to RTV silicone gasket material by a Maine diesel mechanic. He used this to fix a small leak on Beowulf’s Yanmar diesel, and told us that he rarely used paper gaskets anymore. We’ve since carried an inventory of this material. It is good for replacing gaskets, and if there is a mating surface that is somewhat unfair, where a paper gasket is not doing the job, the RTV is a miracle material.

Ventilation (Muggy Memories)

Good ventilation is one of the most important of cruising amenities. Our lessons on this subject came the hard way. We first arrived in the Marquesas Islands aboard Intermezzo in the summer, and we had just two small dorade vents, no fans, no way to open the hatches at sea or when it was raining, and an awning that was awkward to use with blue stripes which increased the temperature substantially. Oh, and the topsides were a dark blue/gray shade, nicely absorbing the morning and afternoon heat. If you want a primer on ventilation, just do the opposite of everything we started out with!

Image When anchored or moored so the boat can swing head to wind, the foredeck hatch is usually best opened facing aft, so air can exhaust through it. Adding a foredeck awning will enable the hatch to be left open during rain squalls. Read the rest »

Preparing Food for Long Passage

Ground Tackle

Ground tackle is probably the single most important system on the boat in terms of safety, comfort, and peace of mind. Our approach is based on a steep learning curve-which we survived-but which we would not want to repeat. The bottom line is this: we assume that we’re stuck in an anchorage where we cannot leave, the winds have put us on a lee shore, and bottom holding is poor. Our ground tackle systems are engineered to give us the best chances of a happy outcome in this type of scenario. The side benefit is that we are totally secure in anything less than awful conditions, and we can anchor on much shorter scope the 99% of the time conditions are favorable. Read the rest »

Understanding NMEA

In the olden days, prior to launching Beowulf, we made it a point never to interconnect electronics. Although a standard protocol for exchanging data existed (NMEA 0183), we felt it was safer and more reliable to have our gear totally independent. When we started to install electronics aboard Beowulf we adhered to this approach, except for the radar display, where we had B & G depth and speed information portrayed. Then someone showed us a radar with the GPS waypoint on the screen and we got another interconnection. As we moved into electronic charting this added a another layer of interconnection – data from the various devices into the PC, and eventually heading data from the PC to the autopilot. While we were at first leery of this approach, we grew to enjoy the benefits. Along the way it became apparent that the actual connections were easy. But we never really understood what was going on electrically and in terms of data transmission. Read the rest »

Safety Gear

What, and how much safety gear to carry is one of the toughest questions to answer. What is right depends on your budget, risk tolerance, space available, and where you’re headed. It is easily possible to spend a very large chunk of freedom chips on this category of gear. And this is against the background that it will probably never be used! We’ve recently been going through this process ourselves. In our case, we’ve got plenty of room on the new boat (83 feet). But just because we have the space, and can afford this gear, does not mean we are going to carry every possible item! Here’s our approach. Easy gear first. Read the rest »

Collisions with Ships

Even though sailboats have right of way over powered vessels on the open ocean, it is always best to stay out of the way of ships. In areas with restricted maneuverability, the bigger ships often have a legal right of way. With good visibility, it is easy to read the ship’s range lights at night (or its masts during the day), to figure out what they are doing, and plan accordingly. But if visibility is restricted, such as in fog, the situation becomes a lot more difficult. On May 28, 2003, the sailing vessel Wahkuna collided with the container ship Nedlloyd in the English Channel. We’ve obtained a copy of the official report on the accident from the UK’s Marine Accident Investigation Branch. The report goes into fascinating detail about what happened on the ship, and the yacht, and what could have been done differently to avoid the problems in the first place. To download a copy of this report, click here.

Stability & Comfort Design Factors

Stability and comfort characteristics with sailboats are relatively easy. The more stable the boat, the faster and more comfortable it is. Since a key component of this stability is the vertical center of gravity (VCG-the center of all of the weight which makes up the boat), designers and builders work really hard at keeping high structure light. The other component of stability is the hull shape when upright and at various angles of heel. More beam equals more stability, but also creates drag. So there is a lot of refinement that goes into how the hull interfaces with the water.

“End-Plating” the Main and Mizzen

You probably know that the induced drag on any foil (water or air) is proportional to the aspect ratio (actually, in some cases this is a logarithmic relationship-i.e., you get big changes in induced drag for small changes in aspect ratio).

mizzen deck seal

Both mizzen (shown here) and main on BEOWULF have “deck seals”. These are small sections of sail cloth which create an end plate effect between the underside of the sail and the deck.

Keeping the Water Out: Mast Boots & Chain Plates

Keeping the water out – now there’s a topic dear to any sailor’s heart!

But over the years we’ve learned how to make boats watertight. Read the rest »

Watermakers

Anjo Sterringa recently approached SetSail about writing an article on watermakers. She wrote to us, “I am a cruiser fallen onto land, (Mallorca) where I now service and install watermakers. There is still a lot of mystery and different ideas about pre- and post-filtration of drinking water on board. I have seen a lot of different brands (Sea Recovery, Spectra, Aqua Base/Aquaset, HEM, Idromar, Aquafresh to name a few) in various conditions.” Having time on her hands while recovering from a broken leg, she proposed researching and writing an article for cruisers on watermaker filtration and maintenance.

Diving Gear

The question of how to deal with underwater maintenance and/or underwater fun is an interesting one. If you go for the whole package it means a significant amount of space, weight, and costs have to be carried. When we started cruising seriously in the 1970s, we felt we needed SCUBA gear to clean the bottom and prop, clear fouled anchors, and for fun and games. Compressors were too large and too complex for our 50-footer so we carried four SCUBA bottles. Of course we also had two sets of wetsuits, two regulators, back packs, etc. A lot of space! Throw in the weight belts and things really got heavy. Read the rest »

Staying Ahead of the Maintenance Curve

Modern cruising equipment is amazingly reliable if it is installed properly, and given a bit of preventative maintenance. That’s been a theme of ours for years. The experience we’ve had on BEOWULF and that of most of our clients is the same. Whereas in the olden days we always joked that cruising was going from one exotic anchorage to another so we could work on our boats, this does not have to be the case. There are a couple of keys to this success. The first is proper installation. This means keeping the gear dry, feeding it with the proper-sized hoses or wires as required, and minimizing the damage that can be caused by chafe and vibration. Read the rest »

A Magical Outboard?

Over the years we’ve owned a lot of outboards. Most have given us good service-we’ve never actually had one deteriorate to the point where it had to be replaced. Our current outboard is sixteen years old, and still running strong. As a year of outboard life is generally reckoned to be the equivalent of 12 human years, this makes it 192 years old.

Refrigeration Gas

There’s been a scramble for the past eight or 10 years for a replacement for Freon 12 (which is now banned) in refrigeration systems. Many marine suppliers have been using a refrigerant called 134A as a substitute for Freon 12. The problem is that 134A is significantly less efficient than Freon 12. The technical literature indicates 10-15% less efficient-but our own unscientific estimate is that it is more like 20-25% less efficient in our marine applications. Fast forward to a couple of months ago when our friend Richard Findlay, a retiree from the heating and air conditioning industry (Richard is currently on the last phase of converting the breakthrough racing yacht EQUATION to a cruiser) sent us some technical info on a Dupont product-MP-39.

Liquids Stored on Deck

storing jerry jugs on deck
In the cruising grounds close to home you see a lot of boats carrying plastic jugs on deck filled with diesel or fresh water. You can get away with this if conditions remain moderate. But it does not take much of a wave to rip the containers (or the hardware to which they are attached) free and send them down the deck and/or overboard. In addition, all that weight stored so high above the vertical center of gravity reduces stability and in a knockdown, can make it more difficult for the boat to get back onto an even heel. Needless to say, we prefer to keep the decks cleared. However, if you do carry jugs on deck, take a look at this photo for a neat way to do it. Those 2 x 6 ” (50 x 150mm) boards, to which the jugs are tied, will double as fender board when tied up alongside pilings.

The Purple Stuff Is It!

We’ve been giving BEOWULF a good cleaning and polish. This includes all of the engine room (even the bundled plumbing and wiring) the dinghy, inside of lockers, and interior hull surfaces. Except for the dinghy, which has stains on the inside from spilled gas/oil mix, and the engine room, which has not had a thorough cleaning in three years, most of the cleaning is a simple wipe down. But for the dink and engine room, stronger measures are required. As a result we’ve done some scientific testing of various cleaners. Simple Green, Zep Purple, and Nature’s Orange, in concentrated and diluted ratios have been used. The result…(roll of drums)…Zep Purple is by far the best cleaner. Simple Green is second and Nature’s Orange is last. The Zep Purple is a wonderful material in the engine room. Diluted at 3-3 we spray it on, do a quick brushing to loosen things, and hose off the dirt. We’re not sure about availability, but we picked ours up at Home Depot.

Zep Purple wins Beowulf’s seal of approval.

Chafe Protection in the Engine Room

Any wiring or plumbing attached to equipment that vibrates is subject to chafe. Eventually this chafe leads to leaks, electrical shorts, and all sorts of dire consequences. It is better to find the potential chafe points before they become a problem. Basically, anytime you have two surfaces touching, where there is movement, some form of chafe protection should be applied.

AC Shore Power Adaptors

BEOWULF spends very little time whilst cruising tied to docks – almost none, in fact. However, now that we are in Southern California, and still looking for a permanent home, we have been doing some dock-hopping. So far we’ve been on docks with 30 amp 110V service, 50 amp 220V power, and now 20 amp 110V power. Each has a different style plug at the dock end.

Preventing and Treating Malaria

Dr. George Kornreich is a retired physician and a sailor, who volunteers in a medical assistance project in the South Pacific nation of Vanuatu. The group he works with brings medical care to some of the most remote island villages of that nation, where the only reliable access is by sailboat. He contacted us about an article that had appeared on our web site about malaria in Vanautu. This led to an email exchange with Steve Dashew, who survived a bout of chloroquin-resistant malaria in Port Moresby, New Guinea in the 1970s.

NOAA S57 Vector Charts: A Revolution for all Mariners

The NOAA S57 vector chart system promises a revolution for all mariners navigating US waters. With the advent of SetSail-MaxSea V9.2 you now have free access to these charts (in fact 9.2 Yacht is shipping with the complete database as of late April 2002). Wanting to find out more about the process by which NOAA creates these new charts, and the schedule on which the S57 charts are being completed, I called Dave Myers, the Production Manager for Electronic Navigation Charts (called ENCs) at NOAA. After a long and fascinating discussion, I came away very impressed with the process being used. Read the rest »

Entertainment Aboard: DVDs & MP3s

It is 2200 hours, and we’re en route between the British Virgin Islands and Panama. Wind is on the quarter, 13 to 15 knots, and BEOWULF is slipping along at a comfortable pace of 11 to 12 knots. In the pilot house we’re experiencing something new. Our navigation computer also has a DVD drive, and our first movie on watch, Moonstruck, has just finished. It was great fun, and what surprised us the most was how clear the movie image appeared from across the pilot house. The two of us were eight feet away from the computer screen (15.7″) and the image was bright and sharp. Read the rest »

Satellite Communications

From time to time we get questions about various forms of satellite communications and how they work. This is a huge subject, one with a lot of trade offs to think about. If one of the hand held systems, like the now defunct Iridium (which may be coming back) or Globalstar makes it, that would be great as it provides a compact and relatively low cost approach.

Fixing Leaks in Metal Tanks

Most metal fuel and water tanks occasionally develop small leaks. These usually occur along welded seams and can come from faulty welds, electrolysis, excess flexing of the tank, or acids in diesel fuel. Most leaks are pin-size, tiny holes, and can be closed with a punch and hammer. Once you find the leak point, take a center punch and/or a “drift” (like a center punch but without the point) and “punch” the leak point. This will smash the soft weld metal into the hole to for a seal (this is the process that builders use to seal small leaks when testing tanks). Read the rest »

Medical Supplies

In all our years of cruising, we’re happy to report we’ve never used any of the serious medical stuff we carry aboard. By now, the total of supplies we’ve either thrown or given away amounts to thousands of dollars. Even the rubber and metal products have had to be replaced several times. Yet we still carry this stuff, hoping we’ll never need it. Read the rest »

Powering Up

two spinnakers from aft
We’ve been looking for the edge of the short-handed cruising envelope for a lot of years. Improvements in sail handling gear, materials, and our own experience have allowed us to push the horizon further and further. And even though BEOWULF looks pretty aggressive for a couple of grandparents, she is not yet at the edge of what the two of us can handle. Read the rest »

EPIRB Registration

The registration you filled out when you purchased your EPIRB is good for two years, after which it needs to be updated. Failure to update means valuable time may be lost if you ever need to use the EPIRB! You can get data on line at http://www.sarsat.noaa.gov/beacon.html , or in the US call 301-568-8649. If you don’t have your beacon ID number handy, the folks at the registration office can look up the data for you with the name of the vessel and vessel owner’s name. They will then fax you the form to update. Also, remember to check the replacement date on the battery. Most are good for five years. Read the rest »

Shackle Replacement

Image Spectra Lashing In the olden days, before turnbuckles and shackles, all sailing vessels were rigged with line. Now, with high-modulus fibers, we’re making our way back to the old approach. Today, many racing boats use multiple wraps of spectra or vectran line to make the same connection that used to be made with a stainless steel shackle. Read the rest »

New Source for Traction Batteries

We’ve been using “traction” batteries for years in our boats. Our experience is that these have the best ratio of cost/space/weight to USABLE amp hours available. The cells we use are typically guaranteed for 1500 80% cycles! In the marine field, assuming you equalize them periodically, they will last 15 to 20 years, and withstand a huge amount of punishment.

Maintaining Your Cool: Ventilation for Cruising in the Tropics

Good ventilation in the tropics is a key factor in enjoying the cruising life. This applies to charterers as well as full time cruisers. It also applies on those hot, wind-challenged summer days closer to home. One of the keys to maintaining onoard ambience is a good flow of wind through the interior. This can often be augmented with wind scoops over hatches. When working out the rigging of the scoops, one also needs to consider reduction of sun load and protection from rain squalls. The three photos below give some interesing options (for more information on awnings and wind scoops see pages 152-170 in Offshore Cruising Encyclopedia).

Stainless Steel Welding Rods

From time to time we seem to need a bit of thin rod stock-to replace a hinge pin, or make a catcher for fishing wires of ropes. The cheapest and most diverse source for stainless steel rod is a welding shop that does stainless work. Pick up three or four pieces, typically three feet long, in different diameters. They will come in handy one of these days.

“The 83ft-long (25m) wave-piercer...could easily be mistaken for the spawn of the Royal Navy with its unpainted battleship grey, all-aluminum body. But that day, in those conditions, it was the only boat that I would have wanted to climb aboard to face the English Channel.” --Motor Boat & Yachting
