I noticed an odd discrepancy in the Barto plans, in that sometimes it is referred to as a 13'4" boat and sometimes as 13'6". I shrugged this off as a typo at first - no biggy. The Chapelle plans list the boat as exactly 13'6.5", though. I thought, hmm, which is it, and if they're different, where did the other 2.5" go?
I've been studying the offsets of both plans, and so far I can only find one place where they differ in length. The distance from Station 12 to the end of the Transom on the Chapelle plans is 13" - on the Barto plans it's 11.5". I guess that means the Chapelle transom has slightly more rake in it to be a tad longer. But that still leaves a missing inch somewhere. Anybody seen where it went?
There are some other slight differences in the offsets here and there, mostly by an eighth of an inch in one measure out of maybe 10. I've found what appear to be obvious errors in both (like where the measure says 6" wide when it must surely be 1'6"). But for the most part they are identical.
Anybody notice these differences? Any idea why Barto would have shortened his boat? (Maybe to reduce the angle of the transom to make all those compound curves easier to twist into ply?) Or is there another error somewhere, and if so, which is right?
Something tells me that once you start laying things out you could make it work either way. On the other hand, it could really s*ck to find out otherwise when the boat is 3/4 done.
