We're at the early stages of designing our Eco XR21 and deciding what size to make its planing pad.
I haven't measured my pad but that looks to be approximately what it is. Fr@nky's is different as his XR20 used to have an inboard and water jet fitted. My boat is a few miles away at the moment on it's trailer, but next time I'm up there (some point this week) I will measure it for you. It's triangular in shape and starts pretty much where the V of the bow would normally start forming the keel, if that makes sense
