Yes. There are lots of mathematic formulas. People go to school for years to learn those formulas. You might try here...

No offense intended, but seriously. Asking a bunch of strangers on a public internet forum is NOT the way to go about this sort of thing. To do this right, without wasting a lot of money on modifications that will only make your boat sail worse, you need to hire a qualified marine architect. That's going to cost a lot of money.

You would probably be better off to just sell the boat you have, and buy one that was designed and built for the sort of racing that you want to do.

Re: Keel weight

I am not going to build it all alone, i will try finding some professionals, that could help designing and build the the keel so it stay in place and do not brake something.

With all due respect, designing the shape, weight distribution, and supporting structure for the keel is one of the more complex design and engineering aspects of designing a boat. The quote a above suggests you probably do not have an adequate understanding of the way the loads work to safely design a keel and its attachments.

Re: Keel weight

You might start with carefully matched scale models before working on the big boat.

Re: Keel weight

Lighter and deeper could still put more stress on the structure, 'depending'.... Do you have the skills to know what shape/foil to use? to maintain (or improve) the center of lateral resistance? This is all pretty technical stuff, - if you're confident you could have some fun trying something new. But don't be surprised if there's no dramatic improvement (or worse) without some input from the professionals.

Re: Keel weight

This is designer and engineering territory.. the hull and reinforcements would have been designed for a certain weight/righting moments of the original keel.. attaching a heavier keel could cause issues. I think you need to tread cautiously here....
