Detected by AI from open-source aerial mapping imagery and may not reflect current conditions. This information was not provided by the MLS or listing broker. Always verify dock infrastructure with the listing agent.
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.
