Re: Bob Perry's take on Wolfenzee's dream boat
wrt not knowing just how much effect a cf spar has, versus aluminum, and having to take the owner's word on it...
If you know the weight of the spars (cf/vs/alu) and you already presumably have some numbers for the mass, distribution, etc. of the hull and keel and all, can't you run some numbers in one a them new computer things, to see just how much the small change in mass above deck will affect the way the boat rocks in different sea states?
Pardon me for not using all the correct technical terms, but I'm not an NA.
