WE have an ST6001 with S2g corepack and linear drive
. We are on a Privilege
. The ST6001 gives you 9 levels of responsiveness. The lower level responds slower and actuates the drive a lot less. The upper levels respond almost instantly to course deviaions caused by wind
. If you set your "response" level at 1, the autopilot
seems like it only responds every 15 or 10 seconds or so. At level 9 it seems like it is constantly correcting.
I tried looking at the energy consumption
while I was sailing. I had the "response" set at 3. It seemed like on average it was about 2 amps per hour. It is difficult to say for certain because I have solar panels
generators that were giving me variable input and refrigeration
, fans and heads going during the 3 hours I was at pure sail. Sailing on a catamaran
requires a lot less rudder
and corrections than a monohull
. I have had the autopilot
fall into standby and not notice for 15 minutes because the boat was holding course. Heavy winds and seas change that equation, but any really heavy seas I am at the helm
You'll probably find the autopilot is less of an energy consumer than other things on the boat. You may find you motor
sail a lot more than you expected! That has been one of my biggest surprises!
