Question 1

Initially both boats are stationary on starboard tack, but then start moving astern by backing their mainsails.

From position 2, Blue pushes harder on her mainsail and at the same time sculls forcefully on the windward side to make the boat move rapidly sideways (crabbing). Flag Y is displayed. What should the call be?

Question 2

Would the answer be different if Blue began crabbing from her stationary position 1?
