I have now used my ST1000 for about 6 months and found it has a limited performance in winds above f4 or moderate seas although recommended for a 25 foot yacht. I sail single handed and depend upon the pilot holding the course when I need to attend to the genoa halyards. The yacht is then prone to broaching. Should I then increase the size of autopilot or am I expecting too much. A.E.

Hi Alfred, have you tried experimenting with the rudder control on the autopilot? That can make a big difference. All autopilots are happiest in flat water, but they can be encouraged to co-operate when the going gets a bit tougher! It may be that you could get better results by shortening sail sooner as the wind increases, which would reduce the amount of weather helm, and therefore the tendency to broach. It is worth experimenting with different techniques, which you can do at no expense, before spending money on new kit. Often putting a reef in to make life easier for the autopilot also makes the boat sail flatter and faster, and makes life easier for the crew, too! Happy sailing.

Hi Alfred,
I would agree with Cathy on this. Not sure which ST model I have but it's likely to be a bigger version (on a 44' Cat). The previous owner of our boat, complained of the problem you are having. We have never had a problem (even in 8+) - but we always make sure that we are not too over canvassed AND that main jib are balanced. Coming from a small boat/dinghy racing background - we are very aware of good sail control and rig setup - which seems to really help such problems. The extra 1/2 knot is handy also :)
Cheers
