The Survitec SeaMaster liferaft offers double buoyancy chambers manufactured from a specially formulated polyurethane (PU) proofed nylon fabric. This fabric is highly resistant to abrasion and impervious to corrosion in the marine environment. Welded seams give the raft an extremely rugged construction. All 8-man SeaMaster liferafts include a boarding ramp, built-in canopy and equipment pack. A lightweight, waterproof, durable valise is available for all sizes of SeaMaster liferafts. Valises are made of a high visibility material. When packed, the valise design and shape make it easy to launch the raft overboard. A space-saving low profile fiberglass container is also available for all SeaMaster liferafts.
