Thanks ffor your interest.  We used the mainsail boom to pole it out and controlled the height with the topping lift and vang,  preventer and sheet yo control fore an aft.  This way the boom doesn't flop around and spill what little wind there is.   It is a very useful sail if there is any wind at all

I thought drifters were asymetrical spinnakers. Yours is hank-on?
