Deep water re-entry

I managed it once for my 3*, cheating by pushing off the bottom, something the examiner hinted at. I've tried stirrups and a number of more creative ideas, but most don't help. As you pointed out, buoyancy aids make a difficult job even harder. While a few people can do it in deep water, most can't ...

Paint

Probably too late now, but I use International 'Perfection 709' 2-pack polyurethane.

It's expensive, but so hard and scratch resistant I've stopped bothering to epoxy/glass the ply hull - so overall it's much lighter and cheaper.

Of course, this assumes you don't hit rocks or drag the boat.

Re: Open canoe on the sea

Think out what can go wrong and practice it in realistic conditions. For example, swamp the boat in conditions when it's rough enough to get waves over the gunwale and be confident you can sort it out on your own (i.e paddle ashore swamped 'cos bailing is a lost cause). Know your boat's limits and y...

Angmassalik

Now I look at the cockpit, I seem to recall that the original coaming was a flat circle set at about 30 degrees.

There seems little doubt about the hull and bow deck.

Dude this is not such a good idea. Have you had a think about the speeds people travel in surf? How hard it can be to spot people in the water at these speeds?

An article explaining the difference......... http://www.sopsa.org/Article_Similar.htm I'm not sure about para 3. Never heard of relativity?

Low impact / low visibility camping

There are some good general rules for hassle free wild camping, these are: Tent up after dark, down soon after dawn. I tend to cook before the sleep site and breakfast after leaving, so you spend less time actually 'camping' i.e. with a tent up. Groups are hard to hide, a couple of people are not. Y...

The problem with silicone is that nearly all of it gets squeezed out from between the washers and deck, however what remains seems to do the job.
