Hey all! I've been lurking for awhile, and decided to post a question. I got a love for dugout canoes, especially the style you see in Venezuela and Guyana that (I think) the Yekwana and related groups make. I've personally seen some when I was in Guyana in the past. Something like this. I'm hoping to make one soon, and I have sourced a big white pine log. I am in the US Northeast (New England) so it's a big Pinus strobus. Though it's my first canoe, I think I have a decent idea of how to go about it. Felling, de-limbing and de-barking, flattening top and bottom, drilling depth-guide holes, hollowing out, fire, etc. The journey will be a great experience and teach me a lot. I am estimating a 20'-25' dugout of White Pine will be roughly 150-250 lbs in weight... But before all that, a question sprung up in my head. I believe dugouts are normally kept in the water until they're unusable, and I've heard of them being sunk with rocks during winter (in temperate areas) to keep them from drying out, cracking, or splitting, etc. Now, let's say, I want this dugout canoe to last more than a year or two, and I do not live by the water, and cannot keep it on/in the water permanently for fear of someone stealing it. So, the logical next step would be to apply some sort of finish to it for its longevity, yes? I know traditionally, Chinese ship-builders used tung oil... but I'm woefully ignorant of whats commonly used today, or what might be best for a dugout canoe. Are there special concerns I should have? Should I give it many coats of tung oil, or should I use some sort of maritime paint? or spar varnish or... Any advice appreciated, thanks!
