As I passed under the Sakonnet River Bridge which reports 65 feet of
vertical clearance I was contemplating the air draft which I do not know
precisely.
The I dimension is 45 feet. Using the diagram at sailboatdata.com I
estimated that the ratio of the length from the masthead to the water
line is 5/4.1. This yields a distance from the waterline to the masthead
of just under 55 feet (54.88 feet). To that I would need to add the 3.3
feet for the Garmin wind transducer to obtain 58.3 feet.
Is the 55 feet to the mast head plus antenna and wind instruments
similar to other owners' estimates?
Thanks.
