We spent three summers in the Sea of Cortez
north of Puerto Escondido and did a lot of stern anchoring (probably 1/4 of all the nights we spent there).
Many of the anchorages are exposed to the Sea of Cortez
usually from the NNE to the SE quadrants. The prevailing two to three foot swells are from the SE. The daytime winds are from the E and SE and then slowly back around to the W and NW as the sun sets, the land cools, and the wind starts coming down out of the hills.
If you let the boat swing it will end up broadside or stern to the prevailing swells as the wind comes off the hills. Therefore, we would deploy the bow anchor to keep the bow into the prevailing swell and the stern anchor close to shore to keep the boat from swinging around into the offshore
We did not follow that procedure several times and each time we ended up being awoken at 2 or 3 AM as Mirador rolled and rolled 'cause she was broadside or stern to the swell.
And, as mentioned above, we used the stern anchor to hold us close to shore in the far SW corner of the Zihuatenejo anchorage for two months.
We have an Anchorlina self deploying system on the stern. That is 200' of 2000# 2" webbing attached to 15' of 3/8" chain and a 22 pound danforth anchor. There were many nights where Mirador was stern to 5 knots gusting to 30 knots and all the weight was on the stern line and anchor. It never failed us.
We set the bow anchor where we want it
Back Mirador to where we want the stern anchor
Drop the stern anchor
forward until the bow anchor has the correct scope
Tie off the bow anchor
Back down on the bow anchor to set and then test it
Tie off the stern anchor
Power forward to set and test the stern anchor
During that entire process we never have to touch the stern anchor rode or chain except to tie it off when it is time to set it
Retrieval of the stern line is almost as easy.
Untie the bow anchor
handle in the Anchorlina roller
Back onto the stern anchor and turn handle to roll stern anchor web onto roller
Retrieve stern anchor
Retrieve bow anchor
At no time does any messy, dirty, wet stern anchor, rode, chain find it's way into the cockpit
