An airboat is the way around Grassrivers, where the water is too shallow for a propeller. Official screenshots show them racing across the marsh, one of them with a police boat and a helicopter behind it.
Game Informer’s issue 382 lists air boating among the activities of Leonida, alongside jet skiing, scuba diving and kayaking. How you get one, and whether it can be bought, Rockstar hasn’t said.
Other activities are in things to do in GTA 6.
