Go for It
We have used an Autohelm ST1000+ for two seasons now on our H23.5. Like most things on a sailboat, you can't justify the cost, but they're sure nice to have. It makes single-hand sailing less of a hassle and is especially useful for raising/lowering sails while motoring. Gusty winds and a weather helm give it a fit but under normal conditions it does quite well. Sometimes you have to de-power a bit. The ST1000 will couple to an GPS and track to a waypoint. If GPS tracking isn't desired, there are cheaper units. The current drain depends on wind conditions but it's pretty small and 2 or 3 days of sailing won't kill your battery. You need to be a little creative for the installation. I used standard hardware items, which need to be painted now.It's sure nice in rain or cold to set the autopilot and go below. It's sure hard to see out of those front windows though.KenS/V Wouff Hong
