Would a tiny mastless multihull be sufficiently stable in heavy seas?

Cute, but not practical for me I don't think - I feel an approach with the interior on a gimble would add too much weight and cost.

I've toyed with the idea of a reversible multihull design (i.e. can be operated capsized - or has two "ups", if you like), but am left feeling that it would still add quite a bit of weight, and can't work out a propeller and aerial placement/mechanism that makes it workable. (Using a paddle wheel could make a more easily reversible design, which would be cute, but again probably be relatively heavy and are generally held to be less efficient than a prop - and far less efficient in the kind of seas that could capsize the boat).

 

There was a thread previously on this idea
It seemed to not ever be able to answer simple questions and continue to add complication on complication with no real benefit.

 

Nimble, if you've seen a beach ball take off in a blow you'll be careful of being in one. Imho it's going to swing your nuts out of your ears when it rolls not to mention down each swell...

I guess everyone who ever capsized had the idea at least once...

 

small tri example

I have seen the type of trimaran described before, as a tow bouy on a seismic survey line. It was about 17ft by 10ft and made of aluminum. I took pictures of it at the time but they were destroyed by Katrina.

A seismic survey line is used in all weather and seas, so I know this tow tri had taken a severe beating out there quite often, and survived. It is rather heavy for what you want to do with it though.
