Anchoring from the stern or other locations is a good tactic that can at times be useful. I am surprised it is not used more. This can be used to adjust the sun angle (if it is wrong when anchored from the bow) so it is more pleasant in the
cockpit or even for mundane reasons such as producing less shade on the
solar panels. All that is needed is a thin line from the stern to the
anchor chain. This can be released easily and by adjusting the length the angle can be changed. Very easy to do.
The biggest problem is in crowded
anchorages other boats get very confused when you are anchored, but not pointing into the
wind or prevailing
current.
However, I don’t think stern anchoring is a suitable heavy
weather tactic for most yachts. When I have used this technique even in moderate
wind it creates considerable extra drag, especially when any wave action is hitting the stern.
I would suggest owners give this a try before contemplating adopting it in heavy
weather.
A slightly different technique that I think is potentially more useful is to use a line from the anchor chain to a stern or midship cleat to yaw the
boat such that it presents a slight angle to the average wind. Thus the apparent wind still comes from the bow area rather than the stern but the
boat remains on an angle and on the same “tack”.
Personally, on most occasions rather than fussing with complications I am content that our good quality, oversized anchor provides enough holding
power that I do not need to go out at 3am (why does the wind unexpectedly always pick up in the early hours of the morning?) to deploy something special or rig up a second anchor, as is sometimes suggested. However, it is worth educating yourself about the different possibilities.
Not all boats behave the same way and this is especially the case where the anchoring
gear is marginal for the conditions. Sometimes all the tricks are worth trying.
