When I deploy a stern (very, very rare) I first figure out how much line I'm going to need. Then add 1-1.5 x
depth.
Then lower all of that into the dinghy.
Once it's in the dinghy, I continue paying out
rode until the
rode goes from the roller to the seabed, then back up to the dinghy.
Then I
head out, paying out
scope from the dinghy as I go out from the main boat.
When I'm at the end I toss the anchor, then set the anchor from the main boat. You typically will need to pull back at least 1-1.5
depth to retrieve the slack and set the anchor.
To retrieve.... pay out a ton of slack, then I hand over hand the anchor from the main boat out to the anchor, then haul by hand and lash the anchor to the boat hanging about 1-2 feet in the
water. (No I don't bother trying to bring the anchor or any of the anchor rode into the dinghy) Then someone from the boat pulls that line and dinghy back in.
