Is your linear drive electric
or hydraulic? Why did you choose that type? What type of boat
do you have? Size, displacement
Why do you use the linear drive
as primary over the rotary chain drive? Have you noticed any issues with leaving one of them inactive for extended periods? for instance the spare linear drive you keep? or do you periodically switch to the other unit to exercise it?
The linear drive is electric
. The Raymarine
is a very nice piece of kit. Very quiet and smooth.
Details about switching system here: https://fetchinketch.net/boat-projec...ded-autopilot/
The reason we use the linear drive as the primary is that it runs directly off the rudder
post, the chain drive runs the rudder
through the cables
is 53 feet, 38,000 lbs. We switch over to the alternate computer and drive every few days to exercise and test them. The linear drive that is a backup, just sits and waits. It is kept dry, it works when we need it.
