I do sometimes...
It does make tracking easier downwind. It will take a pretty long pole to work with a 150, But I have been very pleased with downwind "wind on wing" sailing when using a pole. It keeps the genoa from collapsing when the winds shifts slightling or when the main might partly block the jib or genoa. I have set mine using the autopilot to steer while I go forward, however, it would be easier with another crew member at the helm or better still, up on the deck doing the work. Is your 33 a newer one or one of the Cherubini designs?
