Skinny hulls
Hi Bob
Swinging on anchor right now so can't tell you exactly, except to say
from memory our 86 footer had a hull beam around 1.5m, waterline say
23m and our new 56 around 1.9m for a waterline around 15m
I recall replacing a broken alternator bolt twice half way to Tahiti
800nm from land & having to slide under the hot engine to get to the
front as there was no way to get round the sides! The alternator also
hot jammed in my chest as I was learning to be a contortionist! Now we
have full walk-around full headroom walk in engine space, civilised,
the way it should be. If it costs me 5% extra fuel I can live with
that. Probably 1 cup of coffee a week to know the engine can be easily
accessed so we can make repairs mid ocean!
For anyone spending a million dollars on a boat and depending on it to
cross oceans I am sure will agree.

It seems to be slow coming, but there is hope! You guys can't mak'em so that
they won't break, but please mak'em so we can fix 'em. And you do understand
they only break under the absolutely worst conditions, don't you?
Thanks, Ed Schwerin

Yeah, a 15:1 L/B ratio seems awfully skinny, depending on the displacement
of the boat. Maybe more flare to the hulls, or a stepped hull that flares
out above the waterline would provide more working room and increased
reserve buoyancy. It's all about compromises.
