Do any large monohulls have positive flotation?

I am not trying to find one to purchase; it is just more of a curiosity. I was reading the Seamanship thread on having a hole in your hull in the open ocean (some good ideas on how to deal with that are posted there, BTW). My Newport 17 isn't really intended for the open ocean, though it could certainly handle a few short stretches (like the outside route from Beaufort to Lookout), but one saving grace it would have in that "hole in the hull" scenario is that it would float when filled. It has some hard ballast and the swing keel, so it is likely it would even stay upright. It might roll every now and then if filled and it would be no fun at all. It could remain intact until help arrived and posibly even make some slow progress. Anyway, mine obviously isn't really a blue water boat; are there monohull blue water boats that have positive flotation?

The ETAP's are all unsinkable but they are more coastal cruisers than bluewater.

I wonder how they handle with that "tandem keel" design. Do any other boats use such a thing ?

I think several years ago someone tried it at an America´s Cup boat, obviously without much success, disappeared again.

There are a few other monohull keel boats that have positive floatation, and IIRC, they were mentioned in an article in GOB about the Etaps not too long ago.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

SailorMitch will become famous soon enough
The tandem keel is but one option for an Etap. I know a guy who owns an Etap 34 with one and he loves it. FYI -- it's an old keel design and not an Etap original.

The ultra-rare sail powered submarine. Not particularly stealthy.
