It just doesn't hold. For example, one day late summer my wife and I were out. Winds were picking up so we decided to put in a reef. Started up engine
, headed directly into wing and turned on auto helm. Waves at the time we about 1' - 2'. A very short time later we caught wind
in the foresail and the auto helm couldn't steer back into wind
. Note: we hadn't totally released foresail sheets
and wind had not changed direction. The boat had been turned so the foresail was backed.
More info: The boat is a 1990. I am assuming the ST4000 could be almost that old. I never thought the auto helm was calibrated because the fluxgate compass
was just screwed to a board that was laid flat under a settee. I had corrected that right away after we took ownership
So a week or so after the example above we took to the calibration task. One of the tests to be done is to check how far over or under "Otto" went with a course change. I believe the instruction was to push one of the "+10" buttons either 4 or 8 times. The boat never stopped turning!
The auto helm works fine when we head
into the wind under power to raise or douse the sails
, or when running under power only.
I've tried the tack function. It worked, sort of. Took us through the tack but then less than a minute later it was steering somewhere else.
After discussing with others at our sailing club, the conclusion is that Otto is just plumb worn out.
