I have used a variety of available setups depending on the situation from diving
off a lee wall to beaching in a heavy surf line.
I use a stainless strop to secure to a rock face hole in the wall, test well before diving wall....last diver releases and we drift clear of wall.
In surf...Danforth Anchor and 15 ft chain setup has a fixed rode of 80ft with thimble. (Mantus seems better)
2nd line is lead through large thimble and clipped to bow ring.
Well Set anchor outside of surf line then row back towards beach paying out 2nd line while controlling bow .
3rd line is already attached to stern as beach line which is taken ashore and held, while offloading.
Then 2nd line is pulled in, beach line paid off to pull empty tender well clear of surf line, so tender rides easy while still pointing into swell.
Secure both working lines ashore and you are ready to pull back under control when ready to leave.
This works especially well if you need to make a number of trips back and forth as you can buoy and clip the working lines in place to bitter end of anchor rode....so that only one person is needed in tender and those on beach can handle the working lines.
