We have a 16 cruiser w/50 Honda and we fish reservoirs w/little to no current. Our GPS indicates a speed of 2.2 to 2.5 mph. We did not want to add a trolling motor, and have a Permatrim, so no trolling plate. Thus we have added a Cabela's drift sock. That got us to 1.5 down to 1.2 depending on wind. Only problem is that at times directional control can be difficult, especially in a quartering or crosswind. Sometimes I have to pull it correct direction and then deploy it again when we are back on course. As usual things are a compromise, but for us I think it has been the best alternative.
