Re: Bob Perry's take on Wolfenzee's dream boat
As I pointed out in a previous post, one can get a pretty good idea of a boats ultimate stability by simply looking at it .If the midships section bears a closer resemblance to a beach ball, well rounded (( trunk cabin with a high camber on top, a whelhouse with lots of buoyancy in it) then it will have high ultimate stability. If it looks more like a raft (exessive beam, flush deck with not much in the way of buoyant deck structures) then it will have poor ultimate stabiliy. This is before you do any calculating.
Older boats, which Bob mentioned, had no problem with righting themselves in a rollover , before boats became excessively wide and shallow, with flush decks. How about posting the stability curves of some of those deep narrow boats here?
Anyone who believes they can live aboard and cruise full time, without storage ashore, with the amount of gear that takes, and still have a light boat, is self delusional.
