Unfortunately I don't think the rest of us can see it. I can't anyway. 

No I can't see your diagram either.........

Yes thanks and that's an interesting tactic I haven't previously come across.

When a  boat enters the zone clear ahead on starboard at a mark to be left to starboard then she is entitled to mark room from any boat that is clear astern on the same tack, or overlapped on the outside.

However, if the boat is clear ahead mark room does not include room to tack. As soon as she passes beyond head to wind rule 13 applies and she must keep clear. She is effectively pinned on starboard and cannot tack to round the mark.

On the other hand if a boat is overlapped to windward and on the inside  of the boat required to give mark room, mark room does include room to tack.

So the standard team/match racing tactic is to slow as soon as first boat enters zone if she has a boat following clear astern, in the hope that the following boat ha s to dip to avoid contact. In which case leading boat has room to tack. In team racing following boat may well slow as well, to allow team mates to catch up.

right, should be easier with the diagram and info now-

first, a boat which is clear ahead (most likely here) on the same tack or has inside overlap to a boat on the same tack has right to mark room

"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."

so if the Solo was on a higher lane (when they were both on stb) then he can pin the guy in the Snipe out, even after the zone is entered, .......

.....whereas if he is either behind or to leeward at the time of the 3 boat zone entered by Mr Snipe then he had no rights to do this

another bit of an interesting case actually

It's not really changed from the old rules (1980's), The tactics are as described - or:-

IF the Snipe was on port and close to the river bank, then it hails "Water" if it can't tack without hiting the Solo (may need to slow a bit...).

The Solo must either tack - or hail "you tack". The Snipe tacks, fetches the mark, and the Solo now only has the inside overlap for rights.

 

Really it's down to the Race Committee to be careful in organising the course to reduce these problems.

Colin, you mean "room to tack".   "Water" was the old rules.

This has nothing to do with rule 19- it is a narrow river but the case described it is just about rule 18 and the new definition for Mark Room

In the diagram, given "red" is the solo then he had no right to call starboard as the Snipe is clear ahead, to windward and overlapped inside before the three legnth zone. Is the diagram what happened?

If the solo was pointing at the mark and the Snipe was to leeward then he can call.

Sorry to be pedantic but Room to Tack at an Obstruction is now rule 20, because the old rule 18 at marks and obstructions is now split into rule 18 "Mark Room" and rule 19 "Room to Pass an Obstruction"

I agree that this case is a rule 18 case
