    How to find CG

    New builder first boat. Where should the CG be on a hydroplane and how do I find it? Many suggestions out there so maybe someone could nail it down for me.

    It is normally about 10-15% of the afterplane, that is 10-15% back from the back of the front sponsons to the prop.

      What hydro is it and what gear do you have in it, somone may have had the same one and give you a more precise answer.

        I’ve built a 28” wood Atlas Van Lines style boat. It has a leopard 3650 Motor, a SeaKing 120 v3 esc, with a HYPERION G3 CX 5000 MAH 4S 14.8V 25C/45C battery, and a x642 prop.
