These tube kits transform your Walker Bay 8 or Walker Bay 10 boat into a Rigid Inflatable Dinghy (RID) and they increase load and horsepower ratings. A RID combines the best features of a versatile hard-shell dinghy with the utility and stability of an inflatable. Kits are available with tubes constructed of durable 1100 Decitex fabric tube with four air chambers sealed with multi-layer, reinforced seams, or with Hypalon tubes for maximum sun protection
