No, you likely won't be able to get under the bridge due to the hardtop. Not sure the exact clearance, and am sure it varies with water level, but in our little 16' blue fin my head seems close to hitting while sitting. Can definately reach and touch the steel girders. Maybe 5 feet of clearance between top of water and bottom of bridge. I have a 21' starcraft fishmaster, and don't think I could get under the bridge with it, think the windshields would hit. But with a bigger boat you can troll out further from the harbor than what I drew as well.
