I know very little about cats, and was speaking in general about modifying plans.

Possibly it is to do with interference between hulls?

If you are looking for more deck space take out the locker forward of the helm. The frames there can be cut down to deck height like the ones behind the helm and there you go, 3 - 4 more feet of deck. If you need more locker area put it in areas out of the way. Make some copies and play with it. I have done it on numerous boats. Remember anything above the deck is moveable, all the structure is below the deck on Jacques designed boats.

You could put a seat in front of the helm with storage in it, if you feel there is 17" of standard seating room there and a walk way.

Well good luck.

Good luck with Sally it looks like she could be coming ashore right near you at the latest I saw. Hunker down and be safe!!!!!

Jacques addressed why the box in front of the console may not be eliminated or cut down in this thread: viewtopic.php?f=6&t=63702&hilit=CT22+beam&start=30

The water is designed to flow between the hulls per the study plans. No interference at all. Cats are totally different than single hulls, OneWay. Two 90's and over 40 mph's. :D

I question the that performance based on the fact looking through the forum that at one time twin 50s were enough, then 70's and now 90s and even once suggested 115s. With out confirmation of a build and real world results at this point its all academics.

JM came up with the same number and it is in the Study Plans on Page 4. I always like to check it to see if I get the same thing to help the builder over any hesitancy he has. I think you can trust the designer.

Thanks did not realize that was part of the beam structure. Forget what i said on removing the box to gain deck space Kenfyoozed.
