ST-1000
The Raytheon ST-1000 H23 is recommended by the manufacturer for boats to 26 feet, but it blows the 15A fuse when my H23 heels hard in the gusts (weather helm). If you know how to balance your boat and sailplan to kill the weather helm then this might be the unit for you.Most places have them on sale for less than $450 with the hand-held remote (list price is about $600). I installed mine in less than 2 hours, and you will probably need a couple of extensions for the actuator rod, depending on where the tillerpilot is mounted. Good luck!PeterS/V Raven
