Can you ask for water to gybe? (like you can ask for water to tack).

Imagine sailing on port gybe, with another boat on your left hand
side. You are following the shore on your right hand side, keeping out
of the tide. Ahead of you the shore bends around to the left - i.e.
you will need to gybe to prevent yourself running aground.

Can you ask the boat alongside you for water so you can gybe?

THANKS,

Chris
