A rigid hull inflatable boat has its buoyancy tube (7) releasably secured to its hull by toggle stop means such as a three-bar buckle (11) borne on flexible tags (8) attached to the tube which is rotatable so as either to be passable through apertures (15) in the hull or to engage the hull and prevent such passage. Inflation of the tube (7) causes positive urging of the stop means towards such engagement. |
