You really need to consult with an experienced spar maker.

You could look up on boats with the aproximately the same righting momentum,
and add some mariginals.

For stable boats the wind is crucial since it adds as v^2. So you must put
in "your maximum weather" and this part you usually don't know for other
boat modells... and your rig maker will probably ask...??? ...yes! you!

WANTED! Straight, approximative momentum formula suitable for 1 hull dinghy
(no transformation C's added).

I found a momentum formula more suited for cat's (I think):
