Had some health issues --so --have been out of the loop for a while --just catching up .
Some thoughts on foil design and configurations.
,In other words -design idea B S ing ;]
Some class rules prohibit boards or foils outside hull beam ,as result boards and foils have been designed inward from the hulls --the c shapes S shapes L shapes of lifting foils are inward from hull beam .
In proposing a 20 class it might be advantagous to allow them outside hull beam .
In example -With canted hulls the foils could follow the hull line cant below the waterline and angle outward in a T shape--or -- Another very different option would be an inverted Pi symbol type configuration from the hull . Two smaller paralell boards with a base lifting foil in each hull .
Not sure if I,ll
built it
my thoughts currently are to build a 32 ft cruising cat --but what fun it would be as a foiler when the wind kicked in .
have fun .

I'm sure foils extending past the max beam is more efficient, but dang that's got to be tricky at a crowded starting line or turn buoy.
Sort of like a bunch of H-18 with wing racks all going at it... except you can't see the foils nearly as well...
Brainstorming...slightly canted straight boards (~6°) with L's at the bottom...no curves.
Simple
, easy to build, 3 part mold. Insert from bottom. Remove L-foils for beach races, insert regular straight boards from top.
Or build a set of c-boards and t-foil rudders for 98% lift and potentially less drag when it goes light.
