Testing The Underwater Exhaust In Various States Of Trim In Preparation For The FPB 97: Motion Impact

One of the most difficult design aspects to get right is an underwater exhaust. Powerboat builders and designers have been wrestling with these issues for years, and nobody–let us repeat that, nobody–has a pat answer. With conventional motor yachts, there is so much horsepower involved in propulsion that exhaust noise is a major issue. Add in engine rooms that are almost always near the center of the vessel, and the need for–and difficulty with–an underwater exhaust multiplies.

In our case the options are easier. We have very small power requirements, so noise and vibration are minimal. The engine room is all the way aft, so the noise is isolated from the living quarters. The aft location coupled with small engines and big rudders makes it possible to place an underwater exhaust, if indeed it is warranted, behind the prop(s) and rudder(s). This eliminates the inefficiencies that occur when you are injecting exhaust, and the related turbulence, ahead of the propulsion/steering foils.

In the case of the FPB 97, we have a scale model in Wind Horse with which to experiment, which is what we’ve been doing of late. We have set her up with extra payload, so that hull immersion forward and aft is closer to the FPB 97. In the case of the underwater exhausts, this affects the imersion of the exhausts, and how they sound during various sea states.

At the same time, this gives us data on the behavior of the canoe body in unusual (for Wind Horse) load conditions. There are some factors we’ve been studying that point us in a certain direction, and we are testing to see how these work. Changing the trim, moving fuel/water forward or aft to immerse or raise the stern, allows us to get an idea of how the FPB 97 might react.

We are a ways from finalizing things…there are still some configurations to test, but we are zeroing in on a decision.

In the meantime, we’ve made a short video, taken going uphill against a 4-to-7 ft (1.2/2.1 m) sea.

Wicked FPB 97 – Finalizing the Exterior Proportions

FPB 971B a007

There are numerous structural considerations impacting what can and cannot be done with the exterior shape of a design like the FPB 97. The structural requirements of the window mullions, for example, have an enormous impact on the interior and exterior appearance. So too, the connection of the mullions to the roof structure above and coamings below. The deck framing, sole, and roof support systems are other areas that control aesthetic fate. On the other hand, you cannot start the structural engineering, until you have a pretty good idea of the design. But how do you figure out the design if you don’t know the structural requirements? This is like one of those notes that pops up in a spreadsheet program when you’re building formulae that says “circular reference”.

Our approach to this conundrum is based on the WAG principle.

Wicked FPB 97 Tank Volumes

FPB 97 Tank layout

The FPB 97 has a wicked amount of fuel and water capacity, so much so that only in special circumstances would the full amounts of either ever be carried. The weight and position of these liquids obviously have a substantial impact on fore and aft trim and stability. We are dealing with close to 37,000 liters/9,800US gallons of capacity (after deducting for structure, separating coffer dams, and stabilizer coffers).

FPB 97 Hull Shape Released for Building

Big news in the FPB world. FPB 97-1 is underway, and the folks at Circa are hard at work, getting ready for the day when they start to cut metal. On our end, we are ever so pleased to have released hull shape 975-80-C for building. The process that brings us to this point is long, painstaking, and involves a mix of scientific analysis and black art (also known as gut instinct born of experience). As we tend towards obsessive about such topics, perhaps a few comments might be in order.

FPB 97 Interior – Thursday Is The Day

FPB-97-5316-70-18.jpg

The interior decks of the FPB 97 offer many opportunities and a few challenges. There is an enormous amount of volume, which is wonderful to have at anchor, and we want to preserve the sense of openness that comes with that space. But this is a seagoing vessel. There are certain requirements that relate thereto: handholds, furniture that secures one’s body, working areas that are functional in less-than-benign conditions. It is the latter which allows you to enjoyably voyage to those wonderful cruising destinations.

FPB Cruising As A Couple – How Big Can You Go and What Are The Tradeoffs

FPB97--ARC-sunset-5-359-48.jpg

When we first started seriously thinking about going cruising, the accepted wisdom held that a couple could, at best, handle a 38-footer. A unique opportunity came our way to purchase a beautifully maintained and almost new 50-footer, and even though she seemed almost too big, we quickly adapted to Intermezzo’s size, and were happy to have the comfort of a larger yacht. Over the years we went from 50, to 62, to 68, and then 78-footers, all easier to handle for us as a couple than the previous yacht. Wind Horse, at 83 feet, is much easier for the two of us to cruise on than any of our sailing yachts. We think that will be the case with the new FPB 97.

As we have matured (hate that concept!) the idea of taking crew has been discussed  more than once. Since this subject is up for its annual review, we thought it might be an interesting exercise to share the crew vs. no crew reasoning. Although we will discuss this in the context of a FPB 97, the logic applies to smaller yachts as well.

FPB 97 – The Foundation Part ll


Wicked-FPB-Bahamas-103-100.jpg

Where you intend to cruise, and the ambient weather with which the heating, ventilation, and air conditioning (HVAC) have to deal, is the starting point for the systems analysis and their integration into the rest of the design. The space these take for installation has an impact on structure and interior design, and the power needed to operate them dictates the requirements of both AC and DC electrical systems. Sitting in a lovely anchorage in the Bahamas, or French Polynesia, has totally opposite requirements in this regard versus exploring Tierra del Fuego or visiting Antarctica.

Antenna Allowances For The Modern Yacht – A Wicked Conundrum

Growing up navigating by sextant and lead line taught us to appreciate modern electronics. We love radar, GPS, SONAR, and AIS. We are attached to free wifi, and data via cell service.

So the farm – as in antenna farm – is on the design priority list during the concept phase, to make sure there is an orderly way to install them all.

FPB 97 – The Foundation On Which Successful Cruising Is Built: Part One

FPB 97 61 Hull shape 106

When it comes to creating a successful yacht for long distance voyaging, you have to start with the fundamentals, and build from there. Get the foundation right, and everything else falls into place. Get it wrong, and regardless of how cool the boat looks, or how much you like the interior, the real world experience is guaranteed to be less than optimal.

We’ve disclosed the exterior of this Wicked new FPB early because it is fundamental to how the boat functions in a holistic systems engineering context. Likewise the Matrix deck, which is also fundamental. Now come the details about what makes possible the cruising dream to which we all aspire.

FPB 97 – Designed For Reality

“Having a boat that can deal with whatever might happen—no matter what—provides a mental comfort level that defines their view of happy sailing.”
–Bill Parlatore, Editor, Passagemaker Magazine

FPB-97-dink-level-50-1.jpg

Designing, specifying, and building a modern cruising yacht demands clear goals about what the yacht is intended to do. In the FPB Series, as with all our yachts, the first priority is going places (read: crossing oceans) in maximum comfort and safety, quickly, with the ability to operate for long periods away from civilization. Toss in optimization for short-handed passage-making–cruising as a couple should the owners so desire–and you have the ability to go where and when you want, without concern for crew requirements, servicing errant systems, or the schedules of yacht transport companies.

Analyzing Lines of Sight

Wicked-FPB-SIght-Line-Study-2.jpg

A primary design consideration is always what you can see from various places on board. As yachts get larger the sight lines diminish, and you begin to rely on secondary input: usually crew members wearing headsets, calling distance off the dock or to another vessel, to the con. We’d rather see and judge for ourselves. Hence a rigorous study early, the results of which guide the ensuing design.

There are several different criteria we are looking to fulfill:

If you are physically and mentally comfortable, and instinctively know your vessel can deal with the sea and the odd bit of operator error, then you are going to go places, at the drop of a hat.

The Easiest Dinghy Launch and Retrieval – Wickedly Simple

Wicked-FPB-DInk-Retrieve13.jpg

Among the very first things we look at in designing a yacht is dinghy storage, launching, and retrieval. This design aspect is as fundamental to successful cruising as anything else aboard. We have had a simple and reliable system since the first FPB first launched seven years ago, modified only recently by the advent of deck winches that power out as well as in. With booms easily controlled by permanent guys, locked off with rope clutches if required, and the dink stowed at deck level, the process is easy enough to get into and out of the water that we usually stow it aboard each evening.

As simple as this is, we still consider this to be potentially the most dangerous job on board.

With the Wicked FPB we have refined the dinghy process to make it significantly easier and more controlled.

The Point Of Shallow Draft

We used to envy the folks who cruised with shallow draft for the benefits it conferred. There is the obvious, extending your cruising opportunities to areas like the Bahamas (above), but there other significant advantages as well.

Name That Deck: A Wicked Setsail Contest

Wicked-FPB-Magdelena-2.jpg

We have a problem gentle reader, and we need your help. The marvelous space we so prosaically call “Pilot Deck” is worthy of a descriptor more in keeping with the view of the world from this unique space.

A New Angle With The Wicked FPB

Wicked-FPB-WIndows-12-4.jpg

The new Wicked FPB sports some hot angles, not the least of which is the glazing system surrounding the great room. There are numerous advantages to these outwardly angled windows.

Wicked FPB – Following The Path


Wicked-FPB-15-5.jpg


Throughout history, the most successful seagoing vessels have shared common attributes. Take, for example, the greatest warriors and travelers of their time, the fiercesome Vikings. When they sallied forth from their northland fjords, they employed high speed, extremely maneuverable, shallow draft designs to help them expand and conquer their world.

Wicked FPB – The Shape Of Things To Come

Wicked-FPB-11-2.jpg

If you are a regular visitor to SetSail.com, you know we like fine rear ends. Flat buttock lines in particular arouse our instincts. With most yacht designs, there is a conflict here between comfort and performance (and this varies with different speeds, or more correctly speed-length ratios). Typically, you pick a speed regime and sea state and live with the results.

But if you stretch the waterline, keeping other design aspects constant, good things begin to happen.

Clearing The Fog

Wicked FPB 7 12

We took the afternoon off, went for a drive, had a gelato, and enjoyed being outside in the harsh winter for which Arizona is known. We’re down to rechecking basic assumptions (again), finalizing deck geometry, and fine tuning the hull shape. This can be a dangerous time in the design cycle.

The Next FPB – A Breath Of Fresh Air

FPB-WIcked-Vent-10.jpg

When you start to consider powerboat (stinkpot) systems, virtually every decision revolves around air conditioning. Air conditioning holds you hostage. High heat loads from large windows and poor-to-nonexistent shading, coupled with a lack of ventilation, force you to fit large compressors, which means a big genset. Since you cannot do without the genset, you need a second, both of which are too big to just run air conditioning at night, so a small night generator is needed.  All other systems decisions flow from this conundrum.

But what if you had good ventilation, even when there was no breeze, and then coupled this with minimized heat loads?

Getting To The Point of It All

FPB Wicked 5

Most of the folks we know in the marine “business” (an oxymoron for sure) play the game for love, or because they simply have no choice, they are pulled to it. The hours are long, the outcome often uncertain, and the risks higher than many economic endeavors.

Improving On Perfection -The Next FPB

FPB Wicked 2

For years we’ve been wrestling with a way to improve on the FPB 83, Wind Horse. We’ve done smaller, as in the FPB 64: a very efficient, attractively priced, well-mannered yacht. And we’ve worked up a larger version in the guise of the FPB 115, about which we can get excited. But to improve on the Wind Horse combination of comfort, sea-kindliness, heavy weather ability, trans-ocean average speed, systems efficiency, and ease of handling for a couple has yet to happen.
