What’s the difference between Oceanmasters & Coastmasters?

There are two main differences between Oceanmaster and Coastmaster Life Rafts. 1) The Oceanmaster has slightly more space than a similarly sized  Coastmaster and 2) Oceanmasters are equipped with external boarding platforms to aid entry into the rafts while Coastmasters have traditional webbing and hard rung ladder and entry bridle systems.


Although the Coastmasters are not approved for commercial survey or yacht racing applications, they offer superior life saving features and are great value for recreational purposes.


Why is ISO Certification Important?

Our Coastmaster® life rafts are manufactured and certified to standard ISO 9650-2 – the international coastal life raft specification.  In the context of life raft design and manufacture, ISO has many criteria covering all types of shipping, both commercial and leisure craft. ISO 9650 for instance, is a new, comprehensive, technical specification detailing all the materials and manufacturing processes used in the construction of life rafts for smaller commercial and recreational vessels. Performance requirements covering inflation, launching, material resistance, buoyancy and interior space are also spelt out in detail.

12 Year Guarantee (conditional)

Our confidence in the quality, workmanship and reliability of our life rafts allow us to provide a 12 year guarantee for all the life rafts we manufacture, provided they undergo inspections at required intervals in a Great Circle Life Raft’s approved service facility. The guarantee is valid only on return of the guarantee card and subject to the terms and conditions therein.

Deck and Locker Stowage Options

Life rafts can be stowed in two ways: a non-waterproof soft valise for underdeck or locker storage and a hard fibreglass canister for on deck. Great Circle canisters are equipped with two or four handles (depending on the model) which provide a better grip for carrying and also makes throwing into the water easier. Deck mounted canisters endure many years in the tough marine environment and Great Circle’s solid fibreglass cases provide the best in protection. Sealed in its protective envelope inside the canister, your life-raft is ready for any emergency.

The valise option still requires that the raft be protected from chafing and sharp objects and a dedicated locker devoted to abandon ship equipment is recommended.

Canister Storage Option

Neat and low profile hard fibreglass case for cradle or deck mount stowage.

Valise Storage Option

Compact, strong and highly visible polyester case for locker or cabin stowage


Hydrostatic Release Unit for Life Rafts

Salcom Servo-Release™ HRU

Designed and fabricated from tough non-corrosive materials and with an integral quick release mechanism, the Salcom Servo-Release™ HRU represents innovative thinking and real cost saving benefits in automatic hydrostatic release units (HRU).


At a depth of 1.5 to 4 metres, water pressure alone is sufficient to depress an internal diaphragm in the HRU and operate the release mechanism. This offers considerable advantages both in reliability and performance as the releasing system does not depend on a sharp blade, a pyrotechnic device or a battery to release the life raft or beacon.


Salcom Servo-Release™ HRUs meets all international regulations and each unit is individually tested to ensure that it is the most reliable HRU in an emergency situation.

Great Circle Coastmaster™ Life Rafts are the best value rafts available today. With the same critical design features found in our top-of-the-line Oceanmaster® rafts, the Great Circle Coastmaster™ Life Rafts are ideal for budget minded boaters who fish or cruise the coast. They may cost very little, but Coastmaster Life Rafts are manufactured to the highest standards with no compromise on quality, strength and seaworthiness.
