[C320-list] Mast Cranes and Asymmetrics.

[Kirk McCullough]

We outside jibe our asym every time. Just be sure to turn down wind and let 
the sail fly out well ahead of the forestay. Ease the old sheet and manage 
the slack in the new sheet. No problems.

I've even done it single handed with the Autohelm handling the steering.
