how do cats handle big waves?

Is there any study of the combined influence of wind and waves? What usually worries me most at sea is how one part of the boat is in the full blow of wind over the wave crest while other end is still deep in the trough. Anyway thats when I wan't some weight down..

AND ????? Is it floating

I might be asking a stupid question here. Is there any advantage to having daggerboards so you can retract your "tripping hazards" over small keels?

"Floribama" - ****, did he annex Florida overnight when no one was looking?

It is possible to self right multihulls, again check out "The Case for the Cruising Trimaran" by Jim Brown. Most people don't want to go to the effort and extra expense of prepping the boat. It is far easier to flood and bring them up in a somersault over the bows or sterns than from the side, but you will have to wait for the weather to settle down so it has to be habitable inverted.

While it is possible you have to consider the conditions at the time.

If you have trouble breating because of the foam and water and you cannot walk because of the wind and the water sting your eyes and face so you cannot see, what are the chances you're going to right the cat there and then. There'd probably be some waves wash over the hulls as well.

Jump off your boat into the water and try to turn it under man power. The slightest breeze and you won't get anything right. Then imagine the boat going up and down, and not in unison with yourself, while turbulent waters swirl around. You'd probably be lucky if you can only hang on.


Unless it's an automated system chances are slim you're going to achieve it even if your crew is in good shape. There was some talk some time ago about a boat that is upright any side up, but it's not so simple. Weather can take days to clear up enough.

The idea is to have the windward daggerboard down, yes. Even better then would be to sit in front of a fire on dry land, meat on the fire and a cold one in the one hand and a hot one in the other

Hi Fanie, I did point out that the boat had to be survivable till conditions improved for a righting attempt. Here is a different approach, why not jury rig a mast on the bottom, reverse the daggerboard and head toward the nearest help? Waiting for your ship to come in can take a long time and keeping busy helps people to survive.

[Fanie]

Well, if the mast can handle the boat's weight, then ample flotation from it may keep the boat from going upside down. There was a vid of a tri that uses the same. Problem is, it's doable on small light vessels, size and weight plays a big role.

How about the hulls can rotate through 180deg. At least something would be ok.

Hope you don't mind that I'm not always exactly on track but yesterday, I took this pic.



Fire is still a bigger threat than the other things we discuss. Notice the buckling of the hull. The resin had fairly well been cooked from the glass.

[Fanie]

Hi Mark, yes that is a sorry state of events, and boats for some reason burn out in a very short time. On land you can run away, from a plane you can parashute out of there, but from a boat you usually don't swim very far.

If that resin wasn't fully cured before, it is now !

[Fanie]

Come to think of it, we also need a system to capsize the boat. Well, if the fire is not fuel related you can put the fire out

Dexterous way to convert glass boat to carbon.

I am of the opinion that there is a great advantage to this, not to mention better performance and being able to explore shallow bays.
