Capsized Atlantic 57 Salvaged

Newt this is for you. I just posted on the other thread and then Googled Anna Capsized and got this.

Re: Capsized Atlantic 57 Salvaged

Thanks Crabby, is this the Chris White boat? It really brings the point across that these boats don't sink, they just flip.
Guess I will have to start looking for another one

That's the one. The blog is here including the capsize.

Sometimes...On another thread there is a story of another that that did not capsize but sunk due to a broken hatch.

Re: Capsized Atlantic 57 Salvaged

Building a multihull that does not retain positive buoyancy, whether inverted or rittled full of holes, should be considered a criminal act.

Why should that criterium be different than for monos? Lots of those sunk also.

And a criminal act? Really?

Re: Capsized Atlantic 57 Salvaged

I would say more that building a cruising cat with a length/beam ratio of >2 (like Anna) should be a criminal act. Not that I know anything really, but I would want to aim for L/B closer to 1.5 if I ever went a bit funny and wanted to buy a cat...

Chris White on the capsize

Mr White himself has made a statement and the article is quite good:

Re: Capsized Atlantic 57 Salvaged

Yeah, criminal. We have so many stupid laws, at least positive buoyancy on multihulls makes sense and can usually be achieved without significantly impinging on living space or having a negative impact on performance given the fact that multihulls are by their nature compartmentalized.

Positive buoyancy on a lead mine monohull? Inverted, full of holes? You're smarter than that, at least I think you are. Or maybe not. Perhaps you would like to argue why they should be the same?

The A57 has a L/B of 2.03, which is for all intents 2. A L/B of 1.5 on a 57' boat would be a 38' beam. This would be closer to a trimaran number - way too square for a catamaran.

I think calling for certain designs to be criminalized is hyperbole, and you are smarter than that. But even if so, why shouldn't mono's be held to the same standard? Doesn't make sense for them not to.

And the lead is not the issue - there are positively bouyant mono designs.

Re: Capsized Atlantic 57 Salvaged

Stupid question as I'm not a Cat sailor, just barely a sailor actually.

I've often wondered why an overload device isn't fitted to the main sheet?
Yes it could cause problems once you have lost control of the boom, and the boom could even be fatal, but it would be like an air bag in your car, that is the accidents happening, all your trying to do is lessen the blow. It should prevent capsize, extremely rare though as they are.

Re: Capsized Atlantic 57 Salvaged

You're right I am being silly. Given the fact that most multihull designs can be readily adapted to retain positive buoyancy and provide a habitable survival platform either inverted or full of holes, I would think it a shame they are not all made this way.

I read Chris White's excellent book "The Cruising Multihull" when it was first published and have been a huge multihull fanboy ever since. For better or worse I have ended up with a mono and I acccept the fact that my home may someday sink beneath me, as to convert my boat into one that would not sink and function as a habitable survival platform in the inverted position or full of holes would likely otherwise render it non-functional for it's intended purpose.

I have considered most of my options and about the best I can hope to do is to install a watertight collision bulkhead in the bow. I hope that is enough but I am open to any suggestions.

My boat (mono) came equipped with mid-boom sheeting that lead to a self-tailing winch mounted on the cabin top. The first thing I did when I got the boat was to get rid of the wheel and install a tiller. The second thing I did was to get rid of the mid-boom sheeting and put the mainsheet back in the cockpit. This change allows me to drive the boat from anywhere in the cockpit with the mainsheet in my hand, ready to be eased in an instant.

Of course this arrangement is not so convenient when sitting at the dock, but in my mind getting knocked down because you can't ease your mainsheet at a moment's notice is worse.

I would not worry about it, odds are you and I will die of something much more common that tearing a big hole in the hull and sinking. There are many yachts crossing oceans and while some have lost keels and others have broken up it is still a very rare thing to happen and I guess this is why it grips our imagination so much. Comparing the cruising lifestyle to most other things I have toyed with most of my life I think its a good bet that cruising is one of the safer things to do with ones time.
