Thanks for the original post, and all the helpful replies. However, without any implied criticism or second-guessing, and knowing how complex this is, can we learn more from this for those of us with less experience in these conditions? For example, can those of you with more experience, provide a list of suggestions for how to minimize the likelihood of problems arising, sort of like a checklist that one could review periodically as a reminder of what to do/not do. I know a list can't cover everything, but it may be helpful nonetheless. Things I have in mind are:
1) Make sure you have checked all systems on the boat, replaced/upgraded any questionable parts, and everything is working smoothly before departure.
2) Have spares, as many as reasonable, for parts most likely to fail.
3) Familiarize yourself as much as possible with how each system works, and how to fix it to the extent your abilities permit.
4) Imagine various emergencies that could arise, and think through how you would deal with them; make any adjustments in equipment, etc. that would make dealing with these a bit easier.
5) Try for redundancy where possible, so that if something fails, there is a back-up (most of us do this with having two or three
anchors on board, but there are other areas where this could also be helpful).
6) Have as much information available as possible--gps,
charts, cruising guides, repair books, etc.
7) Check weather before departure and frequently while underway.
9) Organize the boat so that things you need quickly are readily at hand.
10) File a plan with the right people, and update as appropriate.
11) Try to anticipate problems underway before they become a crisis--equipment not sounding/working quite right, navigation challenges, approaching ships, etc.--ie. think ahead and be proactive.
12) Don't take any unnecessary risks--eg. stay out of the water.
13) Take care of yourself--get enough rest, eat well, take time to relax/enjoy, etc.
OK, I've run out for now. If this is helpful, maybe others could add their collective wisdom.
Frank.
