[Rhodes22-list] Swinging at anchor?

[Chris Geankoplis]

I like the bow eye and painter anchoring method. I’ll try it next year when
I can get to Enosis in Greece. I was given as a gift a riding sail similar
to a Banner Bay sail. I don’t use a boom room so I’m not a windvane and the
boat hunts a lot. With the riding sail it is rock steady. If the swell is
off from the wind I can often bring the bow into the swell for a nice
night’s sleep using an appropriate preventer. I don’t use it if there are
strong  altering tidal currents.
