I asked the same question about a jib and received the following reply from a fellow in the Netherlands.

Hi Howard, I bougt a stock P15 jib, which is 3,78 m2 according to the texel rating. Using a HC 14 jib would be fine, thats 3.54 m2. The blocks of the jib are attached to a line between the two stays.

Trey, this Prindle is in Raleigh but my daughter has never had the chance to use it.
