I thought I wrote this down after measuring it, but I can't find it and don't remember. Is it 43 ft from the water line? I'm going into Charlston SC in a few days and there is a 55 ft bridge. Thanks.
Do you have a sextant? Put yourself at eye level with the deck and shoot the arc to the mast head and measure your distance from the mast. The tangent of the angle times your distance to the mast step will give you the height above the deck. from there to the water is easy.
