I have designed a 16'kayak with Chine Hull designer. (Hard Chine, 16'x22", 280lb dismplacement.) After committing to a version that I felt was as good as it was going to get, I started on the hull. I am ending up with a different boat than I drew. My bottom panel is tenting higher (Highly technichal boating term <grin> )(assume the hull is upside down) than I have drawn. As a result the hull has a draft at the center that is .8" deeper than the plans indicate.
1. Should I have taken the panel thickness off the depth of the side height (reduce the side panel height by 3/16")? I realize that this is very much an R&D effort and that I am gambling with the results, especially since this the first hull that I am building this way. I am just curious how acurate one can expect to be in replicating a S&G design from plans. To my untrained eye, I actually like the lines that I am ending up with in the wood, The problem is that I end up with a descrepancy between the panel shapes and the resulting hull. Does it really come down to a choice of either redrawing the hull that results from the panels or torturing/modifying the panes to come up with the hull that I have drawn?
2. The real question - when do you stop building to the plans and when do you start building to the wood/boat? OR should the plans really describe to within 1/16" what the hull should be? (This post is not a critisizm against the program.) I am more curious when one lays the plans aside and continues with the boat as per say, rather than try to torture the boat to be identical what someone cooked up with paper and pen? I will end up with some numbers on the plans that are hard and fast (distance of bulhead from bow (my zero point)) and others that I have to take off the hull now (the actual station dimentions). I don't see how I could expect anyone else, let alone me in a few months or years, to build another hull from these plans if they don't know which numbers to believe.
