i guess Chris is referring to the fact that modern multihulls can be built with positive buoyancy?

Certainly the cat would have inverted in deeper water but it would never have sunk. Orams are made form Duflex and this has a fair amount of buoyancy built in. Also there are watertight compartments that keep the boat afloat inverted and holed.

you could put a fuse in the main sheet system for safety so at a certain force and main sheet gave way . I know there waves wave to consider but there must be a safety point that at a certain pressure the main sheet broke away from the boom and it was replaceable much like a car fuse

a fuse meaning perhaps a piece of spectra that was knowing to have a certain breaking strain connecting the boom and main sheet system.
Even on a 40 foot race cat it would be nice to have even if you had a pain switch that did that far better to to reconnect that than capsize and you would be still in the race in a lot of race scenarios it would work
a quick release via Wi-Fi on those expensive beasts


you could bring her into Irons and hook up the system again and keep sailing

a quick release main sheet may have helped in this scenario a magic WI Fi button on the skipper some where

Had this happen to me once on a rough day took my stern completely off a skipper let some Joe blow off the street steer and jibbed right into me both were a couple of wankers
even thats bad on a A Class on a rough day

I have heard of the fuse idea but never used it. I think the shock loading in waves would probably make it unreliable.

On the tri Verbatim, there was a light line led inside than led to a quick release cleat. This meant that the main could be dumped from inside and outside.

The MOD 70 shown may have a design flaw. The mast gets canted to windward so when you drop the traveller it can't move far before the mainsheet tightens up because of the geometry of the boom swing (its not at 90 degrees to the traveller like normal booms). So dumping traveller doesn't work on its own.

I like the idea of quick release cleats and NO self tailers on sheet winches. Or ensure that the sheet is removed from the self tailer after trimming on. Self tailers are slow to ease - use cam cleats instead.

I run a dyneema fuse on the Vang/gybe preventer , I can attest to this working :)
A main sheet fuse would never work for me, loads are way too high.

i also run a gybe preventer with 6mm vb cord in the ends at sea breaks at about 500 kg have blown it a few times while running by the lee in fresh breezes
