Steve,
The plans are pretty good, they aren't step by step directions. They provide the offsets for the hull of course, but the uppers are just dim'd out. Some basic construction technique is needed as well, which is available all over the web. For the price, they are a good deal.
I'm basically just using the offsets from the plans, I deviated and went with steel construction and then scaled everything up by 10%. It's an experiment, I may wind up with a big yard ornament, but I'm having fun with it anyway.
Stretching the hull 25 % without a rework of the stations would be extremely risky, It would be 31" between stations. Wood construction? I wouldn't try it. One could take the CAD drawing and redo the offsets, by simply cross-sectioning and adding ribs at closer intervals. I thought about it on this one, but I only increased the span by 2.4". Should be ok. This is my first steel hull, Steel is very strong. Just the frame at this point only welded conservatively to minimize distortion, is extremely stiff. I certainly won't have to worry about poking a hole in it. I've decided to skin the bottom with 12 ga and past the first chine to the gunwale, with 14 ga. I was going to use 13ga, but our steel place has only 12 or 14, ah well, 13 is an unlucky number anyway.
Wes, Yes I'm going to more than likely build at least one more, a buddy of mine is thinking about one for smelly long-chain hydrocarbon power.
I'm not working on it today, some hot automotive job came in today, It sucks when work gets in the way of my hobbies
Thanks for all the great comments..
