Official trailers put boats on Leonida water: coastal runs, Keys-adjacent shots, and shallow wetland craft in Grassrivers-style channels. Water is part of the marketed map, not a rumor.
Map-6 keeps one generic “boat” row instead of a fan marina list. Speedboats, skiffs, and airboat-like wetland hulls may all appear in official video; without Rockstar names, they stay under this type. We do not publish a yacht count or a jet-ski SKU.
No top speed, docking system, or “how many slips in Port Gellhorn” figure is official. Those sentences belong in leak blogs. They do not belong here.
When you match a trailer wake to a coastline on the map, you are doing geography. When you name the hull after a GTA V analog, you are guessing. This encyclopedia only does the first.
