The previous owner of my newly-acquired CP16 had extended the mast about 18" to allow the boom to clear a higher bimini. I haven't had a chance to sail her yet but expect there would be some effect on the boat's handling, especially on a reach. I was wondering if anyone else has tried a similar modification.
Update: Guess I misunderstood the prior owner -- on closer inspection, the mast extension looks more like 8", not 18", so big a deal. By the way, I've now had a chance to sail her and loved it!
