The marina will decide whether they want to...
... jerk you around for the extra length caused by the pulpit or bowsprit.My Cat 27 bow pulpit hangs about 18" over the hull's pointy end, and when the outboard is kicked up, another 18" or so off the stern, and they still charge me for a 27 ft. The max they allow is 28 ft in a 25 ft slip. It's more about width than length anyway. With the length they are concerned about how much the boat sticks out in the causeway.Don't you or the person selling the boat have a tape measure? Don't let this small detail prevent you from getting the boat you want.
