I am similar to Alex 20-25%. From my research, the number of perimeters has a larger affect of part strength vs. percent of infill.

For my sponsons I used 5% with 4 perimeters. For most structures the outside is what counts and the infil mostly provides support. Airplane structures need to be lighter than boats. Below is one approach.
