Introducing Our NEW Search and Rescue Life Raft. The introduction of the Mark-II version of our search and rescue life raft continues the Switlik tradition of providing the most advanced designs available anywhere to recreational yachtsmen. The SAR-6-MKII is the marine version of the air-droppable life raft (Model LRU-20) we design for the United States coast guard's helicopters and fixed wing aircraft. It combines three major features from our earlier designs: - The convertible canopy of our coastal-MKI life raft. - The Toroidal stability device (TSD) off our original search and rescue-MKI life raft. - The twin-tube boat-shaped hull of our USCG approved SOLAS-6-MKI life raft. ... into what is absolutely the world's best blue water-offshore life raft. We build the sar-6-MKII using 16-oz./sq.yd. Nylon fabric coated inside and out with puncture and abraslon resistant Urethane.Any survival or other life raft equipment that can be Coast Guard approved, is. It is constructed with the same pride and to the same high quality control standards as all SWITLIK PARACHUTE COMPANY life-saving equipment.
