Ok Cat Guys...need Some Help
Im building a smaller twin application fishing cat. I notice on the single application that there is a need for tabs..understood. On the twin application like a typical cat it corners relatively flat, and I have used this www.twintrimusa.com devise which makes her handle like a v bottom...really impressed with it. My question is do I need a tunnel tab like I see on some of the west coast cats.. what will they do to help if any..I imagine it settles ride or purposing. Looking for advice..
Thanks Jeff

Tunnel tabs are generally a bandaid for an existing handling/ride issue or on some race boats can be used to squeeze some speed on the very top end of a spec class boat but you pay for it in the amount of skeg left in the water and the boats point of turning being shifted forward (both not good). I dont really see them on many race boats these days. Sure theres a few still out there but as far as an active surface they dont have a practical use. If you have one just set it an forget it, I've seen some use them to help plane but thats about it.
All this may not apply though in your case Jeff as your cat may not really "air out" like offshore cats and a tunnel tab may remain more of a wetted surface.

Thanks guys for the comments above. The boat doesnt really air out. Top speed is between 45-50. Moving cog is being considered since this will be the first twin application. Tabs are needed in certain water conditions on the single when there are more than 4 people on the boat. Just thought it would be nice if need be to have something in case there was porpoising. I guess try it first and can always go back if something is needed ...Thanks Jeff
