That is some horrible, horrible music.

I used to race catamarans. We would 'wear them out' a good brand new boat would last about a year or two.

What would happen to them? Besides the sails losing their shape (sails can be replaced) they would lose their rigidity.

The pontoons would 'walk' wobbling over the waves. The stiffer the boat the faster she was. Cutting through the wave troughs was faster than 'walking' over them.

Just an observation.

Non enclosed life boats must be supplied with a canopy, and the necessary implements to rig it. Usually, tho, the rods are corroded five ways to ****. But then, enclosed life boats are the rule on new buildings anyway.

It's also pretty easy to right an overturned life raft. It does involve going in the water, but then if the life raft's flipped, you're in the water. Life rafts also have "Ballast bags" that will essentially keep them right side up unless something that you'll tell your grandkids about happens.

Survival capsules also exist that are completly enclosed, that can flip every which way and stay afloat. They haven't caught on so much outside of the commercial fishing community, but I have seen concept for commercial vessel sized units. I'm skeptical, but that might change.

Thks for the reply on this. :up:

This is what interests me about the design. Wave piercing cats have been some of the fastest boats on water with very rigid pontoons. I'm interested in how they think having flexible pontoons is an advantage over a rigid design.

Though looking at it they are not going for pure speed per se.
