BILLABONG V1 WETSUIT
Conceived by surfer Shane Dorian, the V1 is a standard-issue neoprene suit fitted with an inflatable air bladder on the back, which is activated by pulling a rip cord mounted on the wearer’s shoulder. Currently available only to pro surfers. Price: About $800.
OCEANIC SAFETY SYSTEMS SRV
Unlike the V1, this inflatable vest is designed to bring unconscious surfers to the surface. Before paddling out, the wearer programs a back-mounted computer to inflate an air bladder if submerged at a given depth or for a given length of time. Available in January. Price: $1,100.
SPARE AIR EXTREME SPORT
Similar to a scuba rig, the Extreme Sport is a vest equipped with a refillable can of compressed air and a miniature regulator. Worn at the chest, it allows submerged surfers to take up to 15 breaths underwater. Price: $300.
EMERGENCY INTEGRATED LIFE-SAVING LANYARD
A battery-powered jet boat, EMILY can be controlled by remote to motor out to a distressed swimmer (top speed: 25 mph), who can latch onto an attached rope. Price: $10,000.
