Yes, definitely a candidate.
Even more weird, the wind in that game is now becalmed: all ships have 0 movement points, but some are still in Full Sails and others have Battle sails

Maybe the rule should be formulated in a way that you can issue Full sails anytime, but if you are stationary, you don't get the benefits until you move forward a full turn.
Conversely, one should lose the benefits of full sails if it stays still...

I guess it would probably be easier to House rule that the rule doesn't exist at all
