I think most people would strongly disagree with this. And helmsman worth his salt can hold a better course than just about any autopilot when he is trying... They however must sleep at some point, and give his full attention to the boat when at the helm, two things that don't apply when using the autopilot.
It will hold a better course than a distracted or lazy helmsman, but not a skilled focused and attentive one.
how long of a period of time are we talking about here?... 2 or 3 minutes,... 20 minutes... half hour?
im not one to strongly disagree here because how the AP performs compared to a helmsman depends on a few different factors...
such as,...
the characteristics of the boat and how it is set up(weather/lee helm?),... the weather and sea conditions,... under sail or motor,...
and even a the very best helmsman will be distracted for a few minutes from time to time if he is single handing.
And it is my opinion that if there is a full crew on the boat doing all the other chores and the helmsman is dedicated to his only job of manually steering, and he is taking his job so seriously that he doesnt accidentally let the craft deviate from its intended heading once in awhile, then he probably wont be the most pleasant person to be around, and he will be completely wore out at the end of his watch.(I know this is the way it is on
some big racing boats, but there are other factors involved there that preclude the use of autopilots)
if the boat is setup well and the weather is relatively decent, I think the autopilot will be more reliable than a helmsman for a longer period of time. and the boat/crew will be happier and more content because of it.
but when the weather or seas turn bad, or while racing and maneuvering for position the helmsman can predict and react according to what he sees and feels. the autopilots we are talking about here cant do that.
the first trip with my autopilot was to a large lake.... we woke up in the early morning and decided to move to another spot on the lake. there was no wind or other boats out yet... glass smooth water.
we fired up the motor and set a course down the lake to the east, with the AP holding the tiller, at 4.7 kts.... after about 2.5miles, we could look back at the bubbles left by the prop wash.... as far back as we could physically see, it was as straight of a course as could ever be made.
I took pictures of it as the bubbles were a light contrast against the dark water in the rising sun, which was behind me....
this length of straight line navigation would have been impossible with someone holding the tiller, (especially me) as a persons senses arent as sensitive as a fluxgate compass and we tend to over compensate at times to make a correction after we see the error, whereas the AP just went to where i told it to and did its job without any deviations, unlike I would have done, all while i drank my tea, ate a couple of pastries, moved about the boat and took photos of the beautiful scenery...
The autopilot will never take the place of the helmsman, but it is by far the single most useful and enjoyable "crew member" you can employ for the cost of it....
