To throw in another topic,
I have been reading through my Wooden Boat books and noted that the displacements on most of these are way higher then comparable sized glass boats. Ex few of the 40s listed on Yacht World are above 20,000 lbs while many of the well known wooden 40s are pushing 40,000 lbs.
Are glass boats engineered for the difference or is it just a cost saving manufacturing thing ?
Whats a good displacement for a cruiser that can do blue water trips? Say a 35', a 37' and a 40' ? To their credit a number of the listed 37s did have fairly good tankage.
