The SeaMaster survival raft is the perfect partner for offshore sailing on recreational or coded craft, designed and refined over many years in partnership with professionals. We have worked with users from a variety of backgrounds to design and vigorously test this raft, which, as a result, has become one of our flaship Seago products.
For a brand which has built its reputation on giving a close knit community of sailors what they need to remain safe in pursuit of adventures big and small, the SeaMaster survival raft truly embodies the Seago Spirit.

NEW FEATURE: The 2021 version of the Sea Master has a new inflatable boarding step as used in SOLAS liferafts

The SeaMaster conforms to: ISO9650-1 (Group A Pack 2)

For vessels that do not need to be coded the Sea Cruiser ISO 9650-2 could be what you need.

Now with 18 Year Warranty.
