This is not a recommendation. It is merely an observation. When we were in majuro there was a boat
crew who had been in the Marshall Islands
for a very long time and had no access to a raft inspection service. They bought a new life raft because their old six-man Avon
was almost ten-years out of date and they did not trust it. After the new raft arrived, the crew announced in the local yacht club that they would attempt to deploy their old raft the next morning, just to see what happened. As you can imagine, this created a lot of interest. The next morning a large flotilla of dinghies gathered around the "test" boat
. The old raft was tossed overboard
and the lanyard pulled. After a very few seconds, the canister separated and the raft emerged. It fully inflated and basked in the glory of cheers and whistles. Everybody took turns getting into the raft and gasping at how small a six-man raft was. the raft was left tied to the test boat for a week or so and never lost
pressure. It was then towed to the near-by swimming area where it became a popular toy for the local kids
. Six month later it was battered but still afloat. Please note that this raft had been kept on the deck rather than hanging on the the transom or slung under the boat and that it had always been protected by a Sunbrella cover. Hope this helps with your desision.
