as some people will know, i am making a f16 from existing hulls but i am a bit worried that id dousn't have enough boancy at the pointy ends, looking at this in a not too tecnical way, i was wondering what the curcumfrance of the hulls is on some f16's say 6",12",18",24" (15cm,30cm,45cm,60cm) from the bow. any ideas guys?

yes but if the volume is not there it may start to, pitch before you reach a speed where foils will do anything so i would still like to know some bow volumes
