We tried the 25 year old Life Raft from Switlik that came on-board the boat we bought a few years back.
Well, to my surprise, it did inflate, looks actually in pretty good shape, but has a leak in one of the chamber. It came equipped with a drogue, tools, and a strobe light (we were very impress !)
This was a cool experience to actually try at least once these devices. It inflated very fast... and the kids loved it
Now, I need to contact the company to see if they offer a service to repackage the raft. If they don't, no big deal since I had given up on this raft a long time ago.
