The invention provides a boat having an air bag fixing structure. The boat includes a boat side plate and an air bag body which is fixedly arranged on the boat side plate in a sealed manner; at leastone air bag supports are arranged on a position where the air bag is arranged, of the boat side plate; each air bag support includes an arc supporting surface, a rubber fixing groove, and a bonding installation surface, wherein the arc supporting surface is pressed against an inner wall of the air bag body; and a first fixing portion fixed with a deck is arranged on an upper side of the air bag body, and a second fixing portion bonded and fixed with the boat side plate is arranged on a lower side of the air bag body. The boat air bag fixing structure can effectively support and fix an intermediate section and two ends of the air bag through the air bag arc supports, and shakes of the air bag due to bumping can be greatly reduced; and bonding between the air bag and the boat body can adopta corresponding bonding fixing manner according to different boat bodies, the fixing strength and reliability of the air bag and the boat body can be enhanced, the service life of the air bag is prolonged, and the safety of the boat is improved.
