Bridge Clearance
The standard mast length is 28 feet. It sits on the deck about 5 feet off the water or less. Add extra 1 to 3 feet for wind vane or VHF ant.So could be 33 to 36 feet total. I always figured about 36 feet for my tall rig (2 feet extra) with wind vane. This is an estimate unless you measure, due to variables like how lightly or heavily the boat is loaded.
