Catamaran designs are inherently dangerous. You shouldn't have to go
around tightening bolts to keep your sailboat from falling apart.

Nor even pulling keelbolts regularly...to stop your only method of
remaining upright falling to the bottom of the ocean...?


That's why Roger MacGregor's so brilliant. Water ballast, man!

Two or three hulls in lieu of ballast is really really dumb. There's
not a sailing catamaran or trimaran made that's more stable rightside-up
than upside-down. Add the stability problem to the fact that leverage
factors dictate greater stresses and you're just sacrificing way too
much in a lame attempt to avoid a ballast keel.

If you fear keel bolts then go with an encapsulated keel. Don't
substitute an unstable design. That's retarded. Another option that's
much smarter is a monohull such as the likes of an ETAP that uses foam
flotation in the hull that makes it unsinkable. People tend to use the
dumb excuse that catamarans and tri-marans tend to not sink because of
the multiple hulls one of which gets holed doesn't make the whole thing
sink. Just more faulty thinking trying to defend an untenable position
and unsuitable design.
