Been using a terova for 3 years on my 18ft Alumacraft. I fish alone and the terrova does all my steering. I've netted fish while going in to 3ft waves. Bigger than that I'll call it a day. This is something I discovered and to be aware of is the 2 modes for autopilot, legacy and advanced. I use legacy as it just uses compass heading and keeps the speed steady when trolling. If use use the advanced mode it will compensate for currents and wind which you really don't need and can cause the boat to slow to a crawl.
