Water Depth & Navigation
Deepwater is a measurement, not an adjective.
Deepwater means the water at your dock is deep enough at mean low water to float your vessel, and that you have a navigable route from there to open water. It is not a marketing term, and it should never be taken on faith.
Verify controlling depth at the dock and along the entire route out. The Indian River Lagoon is a shallow estuary; depth varies substantially outside the marked Intracoastal channel, and a property can sit on beautiful open water while being effectively unusable for a boat with meaningful draft. Ask for the actual soundings, and ask what the seller runs from that dock today.
Then ask about time. Port Canaveral to the north and Sebastian Inlet to the south are the ocean access points, and running time from a dock on North Tropical Trail is very different from one in south Melbourne. Ocean access is a route, not a yes-or-no answer.
