RULE 20

Room to Tack at an Obstruction

A boat needing to tack to avoid an obstruction may hail for room; the hailed boat must respond by tacking or by replying 'You tack'.

When safety or an obstruction (such as a shore) requires a boat to make a substantial course change and she needs to tack to avoid it, she may hail another boat for room to tack. After hailing, she gives the other boat time to respond, and that boat must either tack as soon as possible or immediately reply 'You tack'. Here the windward boat tacks first to give room, then the leeward boat tacks.
