I think cat sailors and mono-sailors should both get the same points. You could argue that cats are 2x the mono's, but mono's are def. more tactical in the field.
Of course, I didn't explain it correctly, what I meant is that for that trophy if you sail only lasers or only cats you will get only half of possible points.
Total score will possibly be the sum of best 5 races sailed with lasers plus the sum of best 5 races sailed with cats.
