An improvement in a snowmobile comprising an inflatable bladder in an initial folded and un-inflated conditioned, operably connected to the frame of the snowmobile by at least one flexible strap and operably connected to an inflation medium controlled by a deployment system. In response to detection of water submersion, the deployment system activates the inflation medium rapidly inflating the bladder, which releases from its folded, un-inflated condition and floats at the surface of the water with the snowmobile suspended and submerged below the inflated bladder, still connected to the bladder by the at least one flexible strap. When submerged the float acts as a recovery device for retrieving the snowmobile and a rescue device for the rider to climb up on. The submerged snowmobile further stabilizes the bladder by acting as a sea anchor.
