Ahh the 12 degrees negative or whatever that is needed. That makes sense, always wonderd about that bump.

Is this the only 24/7 i have seen with it or did i miss it on all the others ?

If not this must have come from one of the earlier molds.

There was a 24 for sale recently in Long Island with that transom bump.....I think it was listed as an Arkma or something like that
