Of course a Fortress CAN work
as a efficient stern anchor. If it is a good idea, depends on the local situation.
How close to shore are you gong to be? Will you have room for a reasonable scope
? In most cases where people are tying a stern line to shore, the shore is very steep, which means rocky, which means your Fortress will be "less than efficient."
In MOST cases, in MOST anchorages
, doing what everybody else does is the most neighborly thing to do. It just means you fit in with the way other boats are sitting.
I am not saying you should, or should not use an anchor instead of a shore tie. Evaluate the local situation and decide. In other words, use good seamanship, and don't make a decision about how to anchor thousands of miles away.
Certainly if running a line to shore, a floating line is nice to have, but not needed. A "reel" is even less of a requirement. Just tie on the bitter end, and flake out the line on deck
, or in the dinghy
, whatever works best for you. If you run the line in a big loop back to the boat
, any hassle on tying up is more than offset by ease of departure.
