I have a ST 2000, I think its rated for something like 5 tons I use on a 7+ ton boat. I don't ask too much of it ,like DeepFrz says. I basically use it just so I can set the sails
by myself . However the other day I put 5 hours on it. Conditions were no wind
5ft. swells . Skipper
green and asleep. First mate on look out and having a blast. It worked perfect. I had a Raymarine
Auto helm on my first boat, I forget the mod.# It worked perfect right out of the box ,as does my 2000. I started out with a Simrad
Navico(on my W28) It never worked right, by the time I called the factory they had changed owners and would not even look at the unit. Just buy a new one they said. So I did a Raymarine !
