Scratch ONE item off the project list: Re-certify life raft.
It failed, badly and is now condemned. Apparently the internal valves that are supposed to release pressure if it gets over inflated are all shot. No more are available due to the age of the raft, and the cost to repair would be half the cost of a new raft even if the parts can be found.
So now the decision is about whether to replace it now or wait.
