Anyone ever turned a Monohull Sail into a Tri-hull

I have a lot of wacky ideas. This may be to far. My Mac 25 is an 83. It's something of an experiment in many ways. Safety is always my concern but I like to think of pushing limits. I see and say, "What if..." This is just a thought and I welcome all input. No, I'm not an engineer but I am an inventor. The reasons for the trihull are, Stability, I can lose the keel(as each pontoon would have a centerboard or make a new lighter keel), More deck space (trampolines). Now, why don't I just get a multihull? Well, where's the fun in that... Dock space is no problem and I would build it to be taken apart if needed. Thanks...

Hmmm

How would you connect the pontoons to the hull? It would have to be real damn strong. Also the pontoons would have to be inline (of cource) with the hull or they would fight against the hull the whole time I think it could be done but would it be worth it?

I've seen one made from a lifeboat...

The lifeboat was about 20-22' heavy fiberglass and a hobie 16 was simply grafted on over the gunwales, retaining all hardware, rudders, etc...but removing the tramp. The owner did it to increase stability of his sailing lifeboat. I'm not sure whether the hobie sailplan was used or if the old lifeboat sailplan was used. I'll bet it was a real dog...

Go for it, I had an old buccaneer 27 I wanted to do that to. Find an old stilletto Catamaran and have fun. Tim Welsh H34 AKA Cabo Wabo

Tri this!

It won't sail like a real tri. The 25 hull is too wide. The advantages of a multihull come from reduced weight (no ballast required) and reduced bow wave effect (from extremely long and narrow hull). Although you could replace the weighted centerboard with a much lighter one, the hull speed due to hull shape would still limit performance to under 7 knots whereas a properly designed narrow hull would most likely sail in the 18 to 20 knot range. Happy sails *_/), MArk

Thanks

I didn't expect such positive response. Thanks. Connecting the hulls will be a challenge. I have to figure out that one. The lifeboat idea is similar. Hobie-like pontoons with a custom frame. Speed is not an issue. I realize the hull won't go past 7. It's more of a stability issue for my family. Healing equals screaming... Plus, projects keep me out of trouble and I like creating. Thanks...

Heeling

Mark, if heeling is the problem, learning how to quickly trim your sails may be the best answer. Your boat will actually go slower if it is heeled beyond 15 degrees, and most sailing can be done below 10 degrees, especially if you avoid sailing close hauled. The key modification would be a good traveler, including control lines that can be quickly eased. Then learn to reef as soon as it occurs to you, or whenever your crew mentions discomfort at heeling. Your crew (like my Admiral) will enjoy the sailing much more. And you will probably be sailing faster! David Lady Lillie
