Abstract
Abstract A pair of jousting poles and a pair of inflatable rafts each raft having a flexible wall for supporting a water sport player in the inflated condition and for collapsing and letting the player down or tipping him into the water in the deflated condition. An escape valve is mounted on the wall of the raft and this valve is connected to an arm supporting a target. When the target is hit by a jousting pole carried by an opposing water sport player, the arm is moved and opens the escape valve causing the raft to deflate and collapse.
