Heading down the Lynn Canal in heavy fog.<\/div>\n

<\/p>\n

Over the last 30 years of cruising we’ve spent surprisingly little time in fog. We expected that to change in this part of the world, but it wasn’t until we were ready to head south back down the Lynn Canal towards Juneau that we got our first taste of sea-level clouds, Alaskan style. As you can see above, the entrance to our anchorage at Taiyasanka obscured. Given the ferry and fishing traffic, we decided to give the weather a sniff outside, and if it looked promising, head on. If not, we could always come back. Even though we’ve got a wonderful radar, we don’t want to start out totally dependent on it.<\/p>\n

Speaking of which, there were a bunch of crab traps in Taiyasanka harbor. These show up quite well on short range.<\/p>\n

In Lynn Canal proper the fog was stratified, and even when we were in the thick of it, we still had visibility for 300 feet (90m) or so.<\/p>\n

There are not a lot of stand-alone navigation markers around here. And you have to look real hard to find this one in the fog, although it gives a good radar return.<\/p>\n

It marks the edge of a glacial river bed, which bends well into the fairway of Lynn Canal.<\/p>\n

About the time the fog was starting to lift we noticed a high-speed target closing with us from astern. It was the catamaran ferry Fairweather<\/em> (rolling along in this photo at 22 knots).<\/p>\n

The bow wave is tiny. There’s a pressure release at the cutwater, and then a secondary bow wave looks to be forming about midway back in the photo.<\/p>\n

She’s pretty clean at the stern as well. As it was dead calm we were running with hydraulic stabilizers turned off, and when their wake came rolling under us, it could barely be felt. In protected waters where the hard ride of a cat is not an issue, this efficiency could be appealing.<\/p>\n

As the fog lifted off the water, it continued its stratification around the mountains.<\/p>\n

We cannot get enough of these views!<\/p>\n

There are lots of commercial boats out with their gill nets, working the salmon run. In the photo above, our radar is in the north up, true motion display. We are at the center of the circles, and our course is southeast, towards the bottom right-hand corner of the image. There are five targets shown with ARPA. Their ARPA vectors are relative, i.e. how their courses are projected to our course.<\/p>\n

\"Image\"<\/div>\n

In a situation like this we also want to know what the actual true vectors are for these targets, which is shown above. We’ve changed the ARPA output to true, and turned on trails as well, to show us what the boats have been doing for the past six minutes (length of the trails is adjustable). You can see that the three boats on our port side – to the right of the photo, are all headed to the northeast, and away from our track. They are moving slowly, which you can tell from their short trails.<\/p>\n

The target closest to us has been changing course. He may have done this to get us to move to the west (left side of the photo) to stay clear of his gill net floats. From our trail you can see the turn we’ve initiated and the projection line of our course now to the southwest (it was previously southeast).<\/p>\n

One thing this part of the world has in abundance is waterfalls.<\/p>\n

You may have noticed that we’ve made these photos a little larger than in the past. Since most SetSail visitors have high speed connections, we thought we’d give this a try. Drop us a line (fpb@berthon.co.uk) and let us know if the size is a problem for your connection.<\/p>\n","protected":false},"excerpt":{"rendered":"
