Does anyone have working mast clearances for the 15, 17 and 23? I know there are factors like load, tide, etc., but just a safe number that generally works with the boats. We can add for the taller mast, if anyone has one and knows how much taller they are. Besides for my own information, I want to post it on the web site boat specs.
