I read over the thread "How to Shrink a Skiff Plan" and want to ask a question about something Terry Haines touches on in post #45. This is not exactly a hypothetical question; for my third boat I plan to adjust a semi-dory design just in this fashion.
If I'm working from a boat's offset tables and spacing between mold sections (that is all three dimensions) and if I create a new set of offset tables and mould spacings by multiplying every offset (width and height) and every mould spacing by the same factor (say, 1.10 for a boat 10% larger in every direction), will the new boat perform in a fashion similar to the original boat? Will the new boat perform in a 10% heavier sea in a fashion similar to the original boat in a sea without the 10% increase in intensity?
Thanks for any help.
