[MHml] Multihull delivery gone badly wrong

[Bill Gibbs]

Photo's of Afterburner capsized show her nets just below the water, as Ross
describes.  Hulls would be full of water from the main hatch anyway, with
all loose gear carried away from the surge.  AB probably has a good 4' of
airspace/headroom when inverted and flooded.

>Its my view that only in the perfect world, where the boat capsizes in flat
calm conditions, will that render there escape to be non detremental to the
safety of the inverted hull.
afterall, if you open that hatch in anything more than a 1ft chop and the
compartment will take on a substantial amount of water.

 as the inherent bouyancy of the boat (from beams etc) take over the amout
of water sloshing around inside becomes irrelevant. all the multis i have
seen inverted float with deck/netting just under the surface even with
escape/access hatches open leaving more than sufficent to shelter from the
elements.
 
maybe a better safety  question to ask the designer is 'how does it float
inverted' rather than the 'will it capsize' - and ask for the evidence
 
after all any boat will eventaully reach a point of capsize, multis happen
to be stable once inverted whilst most monohulls tend to be unstable and
self right
