Lots of fans here of the WP32...
I have one on my H37.5, and it works great. Mine is actually a Navco model, which was a predecessor to the Simrad, but it's the exact same. Like most autopilots, they are not so great in a stong following sea.They do have an internal belt that wears and must be replaced. I seem to get about 18 months out of one, but my boat is at the very high end of weight for the WP32, and I single hand a lot. So it really gets a workout with me.Simrad has been great to me, although that was with their Fl office. They've now consolidated all repairs to Wash state, so i'm not so sure.Search the archives, it's been discussed a great deal here.
