i started building boats with my dad at age 4.
been at it ever since. Completing a 32foot proa, with pilothouse, and a 42 foot horstman trimaran
hulls are the cheap
of thumb is that 2/3 of all time is in the 'finishing' which is all systems other than structure. And 3/5 of all the money
is in the 'finishing'.
so hulls are the cheap part.
when doing calcs for cost, think in EEU or 'engine equivalent units'. So, an engine
30hp new self install for 13k US $ at the moment.
THen minimum is 2 engines for mast sails rigging
for (steering, handling, navigation)
1 engine for (interior finish carpentry, and fitting of piping et al - labor component)
1 engine for (cooking/heating/sanitation et al =the 'house' part of the boat)
1 engine (or nearly) for ground tackle, safety
, et al
1 engine for dingy/tender and its motor
you see, them EEU's add up quick. And note that hulls, are about 1.3 engines....
