The day before the GYC regatta we were out playing and Joanna ended up on my boat (she rescued me but that is a different story) and we popped the chute and she went trapping out while i drove it hard. Oley was singlehanding with the chute and was able to drive much deeper then we could and by the time we got to the other side of the bay he was couple hundred yard to leward of us but not any further behind cause his speed was on par with us.
I noticed that during the regatta downwind the uni over all seemed to drive deeper and with at least the same speed of even the 2up groups that would trap out downwind. Seth was faster and deeper then anyone around and i do not believe he ever trapped out downwind (damn he was fast).
IMHO i would say unless u really practice this a lot and have it down pat Tim is right, the risk of flipping while trying to get out or jib from the wire is to high for the little gain.

Oh and a chicken line can be done, will let Joanna talk about that if she wants. But that is just another thing for me to worry about solo and i think i am gonna pass.
