Bottom line
Boaters should start on the North Flagler waterfront: Olara (275 residences, under construction, 2028) describes marina access in its project materials, and the Rybovich Marina Redevelopment is a planned 19-acre marina district with residential towers in the pipeline. No boat-slip availability is confirmed in the project catalog — dockage, slip ownership versus rental, and waitlists must be verified directly for every project.
A waterfront address is not the same as a boating program. Compare actual marina access, slip arrangements, channel depth and bridge clearance on the buyer's route, and whether dockage is deeded, leased, or waitlisted. Projects earlier in the pipeline may describe marina context without finalized dockage terms — treat every dockage claim as a verification item.
