In the UK, most diving is done from RIBs
(http://www.ribmagazine.com/ribtypes.htm#DIVE
RIBS)
After the dive, the boat picks you up (been following your surface marker bouy).

The normal procedure is to hold onto the boat's grab rail/line with one hand,
release your waist strap with the other.  (handing up any canister lights etc.
to the boat.) Undo Suit inflate.  You then slide your other hand under your
harness and flick the shoulder strap off.
- it is normally quite loose at this time, due to the set being bouyant due
to the inflated wing.
The set can be then spun around your back, and is held by the arm holding the
boat.  At this point crew in the boat take hold of the
set and lift it aboard.
I have built several DIR harnesses for divers in our club who regularly dive
off RIBs and all have no problem dekitting.  The critical thing to get right,
is making sure the shoulder loops aren't too tight - you must be able to place
your hand under the harness and shrug it over your elbow and off.

On the normal diving charter boats in the UK, You generally kit up and then
stride-entry into the water.  As the sea conditions can often be described as
character building, with winds F5 making the dive platform quite unstable at
times.  The one piece DIR harness comes into its own.  With several deco bottles
and a heavy set of doubles on, the last thing you want to happen to you, is
the whole rig to fall apart, just as you get up to jump in.  It happened to
me before I knew any better -  I had a heavy set of doubles on with a stage
bottle crash to the deck due to the failure of a fastex QR clip.  Fortunately
my buddy hadn't jumped in, and I was able to repair the clip with tie wraps.

When I got back home, I took a knife to the harness (a Custom Divers) and
replaced
it with a one piece, and haven't looked back since.
(I subsequently binned the bungy wing as well)

Fastex buckles were never designed to take several hundred pounds of load. 
Sooner or later they will let you down.

regards,
Dave
