What shaped this score

✓Ocean Access

✓Fits boats up to 50ft
Est. waterfront~175 ft

Frontage wraps multiple water edges (end-of-canal or corner lot), so boat fit reflects the usable berth — broker-stated dockage where available, otherwise the canal-end width — not the total frontage.

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.
