I know that- I was being a stinker.

I'm sure you are a very knowledgeable guy, I just have a difference of opinion on a subtle element of the Williamson turn, which isn't very relevant to cruising anyway.

I wouldn't bother with any fancy stuff... helm down..stop boat...sort sails...proceed on recip course..... look for person in water until hypothermia make any further looking a waste of time.... make entry in logbook re loss of crew... proceed on passage.

A good reason to have an extra hand or crewman aboard those long voyages.

You and I think alike Ping.

Re: MOB Procedures

The Down Wind MOB

I got motivated to create this image of a downwind MOB.

Make sense?

Re: MOB Procedures

Without getting into the more nitty gritty of this debate, I do encourage the practice of tossing something (biodegradable and not too valuable) overboard to practice. It can be a sobering experience. We do it a bit, is is fun, and our best effort to date was to retrieve a much prized autographed white baseball cap on a day when it was blowing 15+ knots with "whitecaps "everywhere. Mind you, skewering it with the boat hook was ok for the cap, probably not so good for a friend or the family pet.

But before you do the practice, if you sail in a busy waterway, let the local coastguard know what you are up to so when the inevitable flood of best meaning radio calls come in they know what is going on.

I mean you can see it can't you... "Coast guard, coast guard, coast guard, this is fishing-boat best-intentions, best-intentions. I can see a sailing boat near me doing small tight circles around what looks like a person in the water. I think they need help. Over."

Yes, very good illustration.

Re: MOB Procedures

^^"count to 10"? You are kidding, right?

Also, be aware there may well be preventers, poled jibs, or code sails involved downwind, which will make this maneuvering more complicated and slower.

Re: MOB Procedures

I don't know about counting to ten... I would be doing a bit of MoB triage so to speak... Did I like him? Y/N. Does he owe me money Y/N.. and so on.

Seriously , I would be using the 10 seconds to quickly brief the crew on what I was about to do - doing something suddenly and without warning could see you losing a few more... and if I no longer had crew I would be spending the time sorting the plan in my own head... OK so I'm slower than most..

Each standard that I teach has a pause before coming about, whether it is a windward pick up with luffing sails, or a leeward pick up hove-to.

The count to 10 is necessary to get some distance to be able to come about and get sheeted in. The close haul / close reach back is really fast. This takes less time than the heave-to, sail-to, heave-to go execute under when under white sails.

Try it without the pause. I have, it does not work. 8 seconds will work.

Yep - the other factors will add even more time downwind as you get it stowed. Just release the preventer from cockpit, furl a code O, douse the gennaker with a sock, drop the spinnaker as you come about (that is the really tough one). The poled out jib will be an issue, unless you just furl it; in which case I might consider a windward pick up. But in that case the main will be luffing and will be dangerous.

The downwind is much harder. With white sails, it can be done by one person; but it takes a lot of practice. The other scenarios require more crew.

Re: MOB Procedures

Obviously, there are differences of opinion on what is the best choice of action with regards to a MOB maneuver or plan.

__________________

With respect to those who see it differently than I do, here is how I see it:

I don't like the "Count to Ten" suggestion.

Why? Because:

Ten seconds x boat speed = More distance from MOB

More Distance from MOB = More Chance to Lose Sight of MOB in swells/waves

More Distance from MOB = More time to recover

Time is precious.

Have you ever executed a downwind MOB, either for real or practice?

10 seconds is about 3-4 boat lengths about 6 knots.

Re: MOB Procedures

I should mention, that the first that would follow the MOB off the boat would be a MOB pole.

Yes, I have (practice) numerous times.

Get rid of the head sail ASAP (turn while doing it if possible) & motor back to MOB . . . may not be estheticslly or theoretically pleasing, but seems to me the most practical approach for 99% of real world cruising situations. I might note it's also what the Volvo boats do.

Re: MOB Procedures

My wife and I have practiced MOB many times. Both upwind and downwind and in everything from dead calm to heavy weather to semidarkness.First thing is that keeping the MOB in sight is damn difficult unless you thrown an MOB pole out.


We've dicided that in case of an MOB - punch the MOB button on the PLotter, throw the pole out, start the engine, and turn back.


Let the sails fly, We have a dutchman flaking system and we can just release the main halyard - the damn sail will come most of the way down itself. Haul the boom in tight and find the MOB


All those things can be done from the cockpit in just a few seconds. It is much easier to go back using the engine than the sails. Hauling the boom in tight is easy and means you won't have to worry about it flapping around.


We have personal AIS senders on our vests and we wear our vests whenever we are alone in the cockpit, going on deck (including tethers) or at night. If the weather turns rough, we clip in.




When we have guests on board, they also wear vests and we tell them it is forbidden to fall overboard. Also no one ever pees over the side on our boat - everyone goes below. NO exceptions
