supercat squaretop sail

Hello, I'm new here. I sail multiple types of cats here in Denmark. At this moment we have 2 h16's, one h14t, a nacra 5.8, a prindle 16, a prindle 18 and a sc-17 (my favourite).

We are entering the nacra 5.8 and the sc-17 in a race here around the island (62 miles course, moen rundt)

The main that is on the supercat now is not that large. So I would like to know if there is some experience with squaretop sails on supercat 17's here?

Also I can't seem to find how large the jib should be. mine seems awfully small for such a boat.

TIA,

Steve

Yes they make custom square tops for the supercats but they aren't "class legal".

The self tacking jib is very small... if you dont use a a self tacker... it is bigger.
