Hi,
Ive been talking to ALC today. Im wanting a mast for a 25/26ft boat (which I havent bought yet!!)
Here are some vital statistics on whats available:
Bottom Top Wall Mass/kg
diam diam
177 76 4 45
199 90 3.5 46
202 90 5 65
The wall thicknesses are at the base and get thicker towards the top (by about 1mm). The masses are my calculation.
Ive used Arne's mast scantlings formulae to try to choose which I should go for: the 202mm seems over kill and there's not much in it by weight for the other two but the 177 is cheaper. 199 is stringer but not much (10% vs 177)
Would anyone care to crunch some numbers?
I should say I would like to by a CO26 but I think I'll do more sailing in a bilge keeled sadler 25. Clearly the CO26 has the greater righting moment but the extra beam of the sadler evens things out a bit....I would greatly value your advice!
Best regards
Martin
