When sailing in remote regions such as ours, every advantage counts when things go pear-shaped. Saving the boat is always plan A, but not having a plan B is cutting off your nose to spite your face, IMHO.
For plan A, we have a host of plugs of all sizes and compositions, multiple onboard electric pumps, and unused spares, portable hand pumps, not less than 5 buckets with lanyards and much more in terms of materials than is practical to list here. None of this is terribly expensive, nor does any of it take up an inordinate amount of space.
For plan B, we have a well-maintained 8-person covered offshore raft in a custom cradle with automatic deployment, handheld VHF and GPS, a GPS-EPIRB and life jackets with PLBs, lights and whistles attached.
When traveling, we typically maintain a trained crew of 6 total. Yes, I can handle quite a bit by myself, but it's much easier and faster with more hands helping, short watches make for alert watches and we enjoy the company and conversation.
