I don't have autopilot but I would like to upgrade one of these days. Is it recommended to use autopilot if you find yourself in really tough conditions?
Avoidance is the best strategy, but conditions can be unpredictable despite forecasts. When it gets real rough, I'm steering and counter-steering, adjusting the throttle up and down constantly so I don't stuff the bow after riding down the back of a wave, and generally "white knuckling" it through. Its exhausting.
How does the autopilot do in these less than ideal conditions compared to a person? I'm leery of trusting technology when things are critical.
Hello Paul,
An AP will be a great asset in many "less than ideal conditions" situations as it can steer the boat well (or, at least, better than ME). You may need to control the throttle. In BAD conditions, YOU may be able to steer the boat better than the AP. For the APs that use a hydraulic pump, the capacity of the pump is usually dictated by the capacity of your hydraulic steering pump ramp (volume of the ram in CCs or cu inches). In situations where the AP pump capacity is "marginal" in relation to the steering system volume, the AP will sooner crap out or loose it's ability to quickly make steering adjustments in BAD conditions. (Therefore, when you buy your AP components, size the hydraulic pump so it has adequate 'extra' capacity.) Then, YOU must steer, operate throttle, view chartplotter for maintenance of proper course, etc.
BAD conditions refer not only to wave height, but other factors like wind, tide, rain, wave interval, and whether the sea state is 'confused' as when crossing a river bar or channel entrance.
So, the short answer is NO the AP will not handle ALL conditions but it will be a GREAT ASSET in many conditions.
I currently have a Raymarine Evolution 200 Sportpilot on my Ranger tug 21EC...it has 'patterns' in the computer that let you go in circles, for instance. I had the opportunity to use it out in the Gulf last week. I set it to 1/2 mile RADIUS...and to my surprise it took the tug in a PERFECT circle. Conditions where 10-15 mph SW wind and a 2-3' chop. We where trolling and, granted my speeds where approx 4-5 mph over ground (2-6.5 mph through water). Ride was uncomfortable with beam seas and fine with following seas. Anyway, given the seastate and wind, I thought the AP would give me an 'oval' end product...but NO it was a PERFECT circle even when I zoomed in on the gps later to view the track. I was impressed.
Fair winds and autopilots,
