Hi Peter,
is this the boat type you mean? If yes, then I suggest that you measure up the distance from the bow to the centre of the mast. Measuring the mast height above deck would also be useful.
With these dimensions available, I am sure several can suggest a new sail for you.
Btw. bilge keels or fin keel?
Cheers, Arne
