The hydraulic pump and hydraulic cylinder are from a French company, I do not remember the name but you can find it in posts from Cotemar or myself.
There is a bypass valve. This uses about 1.5 ampere when the autopilot
is active. You can purchase
an Ecopilot electronic circuit which reduces the current
of the bypass solenoid from 1.5 to 0.25 ampere. I bought it, it works well. See my posts about this.
is performing very well. The current consumption
is with the Ecopilot about 1.5 ampere. This is the current of the Furuno electronics
plus the current of the hydraulic pump. Without the Ecopilot 2.75 ampere.
My boat uses now just under 2 ampere, that is with all Furuno electronics
on including the autopilot, during the day (no nav lights) and a Garmin
Excluding the refrigerator
(14 watts average power acc to spec).
At night the power consumption
is not much higher since I use led's everywhere. As a consequence we use average power incl fridge of 3.5 ampere. If we use the batteries 50 % (maximum recommended discharge) we can sail for 2 days (48 hours) without recharging. We did so, last week we sailed to Norway
non-stop in 78 hours. We charged once for 4 hours, when the wind
dropped below 4 knots.
