I looked into the Tiki 38 a little more, part of the extra weight is heavier ply scantlings which means fewer sheets
for the weight. The point is a 1/2" sheet takes the same amount of epoxy
to coat as a 3/8" etc.....One advantage the classic designs have is if you can use tools well, bonding to the stringers takes less epoxy
than making fillets keeping costs down. Those hour build totals seem like the time put in by people who where new to boat building- very high. It is a reminder to project
contemplaters who are not used to production working and building that any construction type may take longer than expected. Buying
is a big cost and the materials loss potential is pretty high. It also takes controlled building habits. Finding a method that is enjoyable to use can make the difference between finishing or not so factor it in on the spreadsheets.
