(Comment on the Photos: Short Dragon is a good boat, but it started rather heavy and gained weight as I added new features such as watertight compartments. He has undergone many revisions, but the revision to very light kayak-replacement and car-top-carried sailing canoe is impossible.)
There is an ancient saying: "You need a boat for everyday of the week." I am not so sure about that anymore, because you can be spread thin, as in, too much bread, too little butter, sort of the way Frodo felt after carrying The One Ring for too long. Apt metaphor. Our things can weigh us down and thin out our attention span. Buddhism is good for that trouble. But anyway, here I am thinking about another boat.
I have my reasons. Now, I already have a trailerable outrigger sailing canoe (you have seen "Short Dragon" here on Instructables). That will be retired as I build a longer one (a Gary Dierking design, Tamanu), but I suddenly noted something: I was often driving by scenic locations on visit back home, where I have always wanted to launch a boat for a day -- but these places were not trailer-boat friendly, or at least trailer-friendly. Therefore I needed a boat to go on the roof of my small car.
Don't you dare say "kayak." I have one, they are OK, but they are too ubiquitous and limited. I need something better -- which means of course, an outrigger canoe. This new concept would replace my kayak because the new outrigger would be light and paddleable. But what is a boat if it cannot raise sail? It is nothing. So now you get it: this is another chasing of the ideal of "the perfect boat."
Yes, it is an unattainable ideal, but I have figured out that if you have two or three "perfect boats" you have gotten as close as is feasible, unless you can sail in Plato's World of the Ideal Forms, and sadly, once there, you cannot move, because perfection implies that any movement in the Land of the Ideal is a movement away from perfection. The wind would be forever fresh but held in stasis, so too the wave, and you and your thoughts.... That world is just plain static, gleaming like a variegated crystal, no doubt, but motionless just the same. Good news! Our sad, imperfect mortal world is the only place to get things done.
I intend to get a little done. This instructable will show the entire process, from rough sketches, to finished product. I will be pissing off a few people because I will build this instructable in stages; my thought process and physical attainments will be posted bit by bit. Viewers may even influence the process with thoughtful comments along the way.
