Auto pilot can’t stand in for a human skipper
Ahoy.
Last week in the Daily Pilot, there was a picture of a 57-foot
yacht sitting on the rocks off Crystal Cove State Park. The story
reported that the owner fell asleep while the boat was on autopilot
from Avalon to Newport Harbor.
The vessel caught my eye because, approximately a year earlier, I
had delivered that boat from Ensenada, Mexico, to Newport Beach.
I remember the boat because it was a new Carver that could get up
on top of the water and cruise at a decent speed for that size of
yacht.
I do remember that I did not give this new boat owner any boating
instructions, and he was not on the delivery with me. Therefore, I do
not feel so bad that he programmed the autopilot incorrectly by
missing the channel entrance by such a huge error at Crystal Cove.
Theoretically, he should have crashed into one of the jetties if
he had the unit in navigation mode with the correct waypoint selected
on his global positioning system. However, he probably was operating
with the autopilot in the auto mode, which is where one simply dials
in a compass heading.
In auto mode, the autopilot will not adjust for set and drift, but
just keep the boat heading in that specified direction -- which makes
sense if the swells pushed him south of the jetty entrance.
I just have a hard time thinking that one could fall asleep in
that short of a time period, as the crossing should have taken
between an hour and an hour and a half with the speed that boat can
do.
He was very lucky he did not hit a ship in the shipping lanes,
considering that Los Angeles and Long Beach harbors combined are the
third-busiest ports in the world.
However, I am very concerned that a yacht was underway on a set
course with no one standing watch on the bridge. If he was too tired
to make the crossing, then he should have never pulled anchor to get
underway and endangered anyone on the water that night.
I consider autopilots one of the best pieces of electronics on the
boat and if used properly, the autopilot will increase the safety
level. The unit can steer straighter than any human operator at the
wheel and, especially in rough seas, frees up the skipper from
tackling the wheel to watching the radar and looking around the
vessel.
I have found that the autopilot decreases skipper fatigue. One
day, I will have to calculate the return on investment for purchasing
an autopilot in the fuel saving costs, as the unit steers very well
and in navigation mode adjusts for set and drift.
Then there are those who misuse the autopilot, thinking that it
can see and think for itself. I have heard of stories of the skippers
turning on the autopilot and going below to make a sandwich, take a
nap or entertain with the guests aboard.
Yes, I have to admit that I have gone below to grab something to
eat or drink, but I slow the boat down to 3 knots -- not full
throttle. The reason for 3 or so knots is to keep the boat moving
very slowly ahead but not getting turned abeam into the swell’s
trough, which could dangerously rock the boat.
My tip of the week is to use your head when underway, and remember
you must always have a watch or two while underway.
Many times in the fog, I will also post an extra bow watch who has
the advantage of the extra distance from the helm to the bow and who
can listen for any whistle signals or engine noises.
It reminds me of the urban legend of the new motor-home owner who,
while cruising down the interstate, left the steering wheel to get a
cup of coffee -- you can image the outcome.
