I have found that not to be the case, but perhaps my experience and yours are different.
This is a subject. MOB
techniques, that I feel passionate about. Hes why the dinhy techniques are useless.
* dinghys are set up for short handed sailing
* what crew there are ( left) are in control
* The dinghy is capable of turning on a dime
Consider the following cruising sceanario on a biggish yacht.
its daylight, 2 crew on deck
, 2 off watch asleep in bunks, boat under autopilot
, speed say 7 knots, wind
f4 approx 1-2 metre swell , fairly typical conditons, lets make it a little easy , boats close hauled, no preventors , one headsail on a furler
* your on crew, other crew is forward trying to sort a problem, you rummaging in the locker for something for him. you hear a cry, you look around, inevitably on the wrong side of teh boat, you look around , then out the stern maybe 2-3 boatlengths you see him waving.
* Everyones initial reaction and I mean everyone, is to go to the rail and look, then you thow the cushions
,life ring etc, etc. Your plotter is below on the nav table , you run below and hit mob, , at this stage you may be 10 boats lengths away,
* your screaming MOB at the crew, who need to wake, get into weather
gear, get lifejackets and harness on. whats that 20-40 seconds at best ( some people are slow to respond). At this stage youve run back up and begun the figure 8 , you put the boat on a reach, easing the sheets
etc. You now need the crew up before you can tack the boat.
* so now the crew are on deck
, youre maybe 20 -30 boat length a way ( a really best guess, in my experience much more). You tack the boat. Now you cant see the MOB. so you detail a crew to go below and call out range and bearing to the MOB, but of course thats useless as figure 8 is not about sailing directly at the MOB and anyway try precise range and bearing sailing , is not easy.
* becuase you must get downwind of the mob, you have to sail off the MOB heading and "judge" when to swing upwind, if youre lucky youll see the MOB, and you can judge it , if not well......
* almost inevitably with figure 8 in these circumstances , you goof the first pass as you either end up above or below the MOB. its go around time.... more delay. and remember theres always, always some controlled hysteria on board as this is somebodies wife or girlfriend etc in the water
. ( its not a cushion or a fender)
* if your lucky on the go around you see the mob, if you dont you now need a box search, again very difficult under sail.....
JUst where is the dinghy experience useful here.
contrast this with , stop the boat immediately , ( ie heave too, crash tack and heave to etc), roll up the headsail ( again all this can be done singlehanded, ) pin the main amidships, start the engine
and go back on a reciprocal course, in all this you might even get time to hit the mob button. While your motoring back the crew will probably make to the deck in time for the rescue
. ( the crash tack in my experience hastens their arrival on deck).
This is my beef with especially figure 8 but generally sail based pickups, the techniques do not scale up to real life. There too much concern with sail angles and sailing and not enough concern about teh MOB. it relies too much on having sharp crew, spotters, proper tacks etc. Doesnt take account of downwind sails
, preventors on etc. ( twin headsails on poles, spinakers etc). it far too armchair based.
it too damm slow and error prone
