[Misdirection]

What autopilot do you have on your boat? I ask because I have an older Simard unit with a Work mode. When in this mode, my boat will track in any condition that I'll fish in. Mine is the old AP35. Its direct replacement is the Simrad AP26. A friend in a similar boat had that model, it would barely go straight trolling with the waves. Likewise, my dockmate has a 33 Egg with a Raymarine AP. Can't troll with it as it kicked off under 2 knots.

I'd suggest investigating your AP to see if there are known issues trolling with that AP and any known solutions.

If that doesn't pan out, I'd contact Tiara and see what they say. Maybe replacing the rudders vs an extension or changing of the props might solve your problem.

Good luck and let us know how you make out.
