I installed NKE
instruments and autopilot on my Open 50. I chose NKE over B&G for its demonstrated
reliability over years and NKE's basic architecture has remained stable.
After 20,000 miles including the Southern Ocean and Cape Horn the autopilot with the L&S drive never failed me. Not once.
I assume that B&G with their newer H5000 system they are catching up with
reliability, but I don't know as I don't have experience with their new system. I do know the older B&G H2000 system couldn't steer the boat properly.
On my next boat I would choose NKE again. Reliability is everything for me.
