My
experience with a Monitor self
steering system on my old Hinckley
Bermuda 40 yawl was less than spectacular. It did best when on the
wind (+/- 10 degrees) but not so well with
wind abaft the beam. I was using it when cruising Downeast
Maine, Bay of Fundy, Grand Manan,
Nova Scotia - mostly coastwise cruising. Bottom line there: I really didn't trust the monitor and always backed it up with an
Autohelm 6000. One day my 8 year old daughter and I were in the
dinghy heading for the boat and she said, "Daddy why don't you take that thing off the back of the boat? It looks stupid!" I mentioned her comment to the foreman at Hinckley's and he said in his thick Downeast accent: "Way-al, when they're right, they're right". So I Had Hinckley's take the damn thing off. I was able to sell it for almost what I paid for it - to a man with an
Alberg 35 and he had good results and was happy with it. The
Alberg 35 is the "big brother" of the
Alberg 30 that Yves Gelinas sailed around the world with his self-designed Cape Horn wind-vane/servo-rudder system.
However, I believe that different
hull shapes and
boats have different responses to wind-vane
steering. Nonetheless, I "upgraded" to a Sou'west 50 with basically the same underwater profile as the
Bermuda 40. I was not interested in giving vane steering another try even though the SW50 will usually self-steer if her course is with the wind forward of the beam. On the SW 50 I have two autopilots, a
Simrad with a
hydraulic steering ram and an old reliable
Wood Freeman and 1680 amp/hrs fueled by 8 Rolls Surrettes in the house
battery banks!
