    Tunnel COG

    Can somebody tell me where the COG should be for a tunnel hull? Does it balance at 30% like a V bottom?

    Chummer, every hull/setup has its "sweet spot" It takes some trial and error to get it right. Start at 27-30 %. The trick is to combine CG & drive angle & height to keep as much of the hull out of the water [without blowing over] as you can. Test,test,test.
