VX40s raise and lower their screacher in between downwinds to reduce windage. It is a lot slower to raise/lower and unfurl/furl than it is to set and drop in a chute.

At the top and bottom mark, you olny want to come in once to deal with the kite. Not furl and drop it later.... You should be on the wire and concentrating on your upwind.

Also, dropping a furled screacher is normally the job of more than one person. One drops the halyard whilst the other gathers the kite. Boats that do this tend to have netting in front of the front beam to give the crew access. You also need somewhere to lash the screacher down. So, a screacher that needs to be dropped is a no go for a small OTB craft. Keeping it up = far to much windage and weight aloft.
