I found that our wind generator (FourWindsII) keeps the boat from sailing at anchor
. It's mounted off the transom, far aft.
We sometimes use a riding sail (a.k.a. anchor
sail) when the wind generator is secured. It also works perfectly for this.
the headsail doesn't make the problem go away on our boat.
And we often anchor
with 2 anchors
(Bahama mooring). That stops her from sailing at anchor when the boat is puling on both anchors. If the wind shifts, she starts sailing at anchor again.
I haven't tried it yet, since the riding sail and wind generator work so well, but a large bucket off the bow might work.
IMHO, for a rental, a (quiet!) wind generator would probably be the best option, since renters wouldn't have to deal with it at all. Other than that, maybe get an overly large dodger?
