Sounds like a good 14 ft cat design .
The fold up plywd method always makes fast rounded V shaped hulls no matter how you cut the outline and fold em up , though they will not lend themselves to any flatter fuller hull section shapes ,--in a 14 with fold up plywd. the designer must leave in a fairly wide deck to create enough volume to support boat and crew weight plus sail forces ,--more w spin ,on the bows particularly.

Built a fold-up and also a 20 cat using the stringer frame method ,-wanted flat hull sections and added volume forward .

With current 14 rules as proposed --no beam limit ,300 sq ft any configuration sail -24 mast , --hmmm
a mini 60 ft foiler tri ? scaled to 14.3 L 14 beam -

Could just use a shortened center H 18 hull with two lightweight amas and angled foils molded in near the bows ,
to carry a large mast head hooter on a furler upwind and down ,--
hmmmm -- 300 sq ft is more than the I 20 main and jib !!

maybe 2 classes will be needed .
