Robert,
"I have used a drag, that is to say a bucket on a dock
line, to steer a single engine powerboat that lost steering".
The drogue I mention is not a bucket, its a "macramé" (right word??) of tied rope, tied with two cables in a "V" shape, where the drogue stays in the corner of the "V".
The two ends of the "V" go, one to starbord and one to port. I wish I could draw it, because its hard to explain. Pass each thru a
winch on each side of the boat, but its a single cable, and just use the ropes to steer. Please go out and try it, Leave at least 20 meters on each "V" leg. Remeber not all boats sail balanced like yours, and not all can balance it like you do. I would never use a bucket.
