To the OP question on MOB pole value. While safety first is always an acceptable default position when sailing I'd summarize the following;
- coastal sailing - probably overkill, horshoe ring is sufficient
- ocean sailing - why not, gives everyone a fighting chance along with a plan
In 35+ plus years of coastal sailing I've been involved with 3 MOB situations. Each one was the classic "hey watch this" manuever where funny guy jumps over board while under a light breeze and realizes "hey that boat's moving faster than I can swim!" Oh yeah, I was one of them at the age of 17 off Green Harbor in early May (only Mass. boys will know this place). It was a beautiful jack knife off a cat, great form until my fingers hit the water and I vividly recalled "this is why I don't go swimming in May" Everyone was impressed, except the helmsman who spun the Hobie like a top and was back to me in 20-30 secs. I remember the struggle to lift my arms to get back on board. I still thank that guy when I see him.
Fast forward to today. I just bought a boat in New Zealand and take delivery in Hawaii around mid August - the wait is the bad news. The good news: the boat is rigged to meet stringent NZ marine safety requirements, including;
- MOB pole with light, weight, drogue, horseshoe - easily deployed
- dditional stern mounted life ring and
line
- back up
SSB antenna with in-cabin quick disconnect
- 2 high volume, manual backup bilge
pumps
- 50 foot fire hose system which can also act as 3rd backup bilge
pump
I'm dialed, now I just need to remember if I turn right or left leaving Hawaii for SoCal!
