That depends on which F16 you are going to use, as they have different hull shapes and different bow shape, ie. some have more volume up front than others.

Are you using the F17? The F17 is of course 1 foot longer so that adds more buoyancy up front too, that will help, you might want to talk to the Hobie 18 guys as that's the boat I've seen most with the wings, that and the Hobie 17's. I've never seen any on a F16.
