Open WaterDockOnly

This dock fronts open water — a bay, harbor or marina basin rather than a canal.

There is no across-the-canal bank here, so no canal width applies and boat length is not limited by room to turn around. Check depth, beam and slip dimensions with the listing agent.

Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map. Verify navigability with a local captain or surveyor before relying on it.
