Oppostie Gybes, leeward Mark

as another example of where the rules could be clearer, the rules do not define what a 'gybe' is, and so given:

'Tack, Starboard or Port A boat is on the tack, starboard or port, corresponding to her windward side.' and

Mark-Room Room for a boat to sail to the mark, and then room to sail her proper course while at the mark. However, mark-room does not include room to tack unless the boat is overlapped to windward and on the inside of the boat required to give mark-room.'

it is not actually clear if '...room to tack' includes room to change tack by gybing.  The problem is that Tack is defined as an adjective but seems also to be used in the rules as a verb.

Surely in the ISAF case book, case 75 gives you enough
explanation gordon.

Although not with kites the principle is the same.

Hi Gordon

Thanks for this - I was unaware of C2.4 13.2 and that is really interesting.  It seems a shame to me that 13.1 and C2.4 13.2 arn't included as definitions in the glossary and generally applicable.

Unfortunately for damp freddie judges apply the rules as written not as damp freddie wishes they were written!

Rules 16 and 18.4 give no rights to a keep clear boat - they impose limitations on a right of way boat.

There is an order of precedence in Part 2 of the rules:

Rules of Section A ALWAYS apply and they define which boat is keep clear boat
Rules of Section B impose limitations on the action of the right of way boat
Rules of Section C imposes limitations on the action of a right of way boat at marks and obstructions, and may give limited entitlemnents and exonerations to a keep clear boat

The key thing to remember is that having mark room on its own only entitles you to a very limited corridor to sail to the mark. You can only do a tactical rounding at a mark (wide in tight out) in the presence of other boats IF you are right of away boat. However ROW way boat must still (until they are at the mark) comply with rules 15, 16 17 and 18.4.

A tactical rounding is not necessarily "good sailing" - it is "good racing" - which is far from being the same thing.

18.4 only applies in limited circumstances - limiting the rights of an inside overlapped right of way boat. 18.4 ceases to apply when boat ceases to have right of way and 18.2a or b applies.

[sigh] No, they didn't. You still seem to be missing the difference between mark room and ROW. In case 75 the inside boat is the ROW boat and can sail where it likes.

The crucial bit about that case for this discussion is that it confirms, in the language Gordon used, the narrow corridor straight to the mark.
