A common occurrence is for a close hauled port boat to tack ahead of a starboard boat causing the latter to take avoiding action. Assuming that port finishes his tack before avoiding action needs to be taken.
1- Is there a rule of thumb to. Indicate when rule 15 has been broken. How close is too close.
If there was no contact then there was room to keep clear unless contact was only avoided by an unseamanlike act or a miracle.
If it was not possible for the give way boat to avoid, acting promptly but no sooner than the other boat actually gained right of way (in this case, reached her close hauled course), and in a seamanlike way, then the right of way has not given room to keep clear.
Relevant Cases areCase 21
When a right-of-way boat is obligated to give mark-room to a boat overlapped inside her, there is no maximum or minimum amount of space that she must give. The amount of space that she must give depends significantly on the existing conditions including wind and sea conditions, the speed of the inside boat, the sails she has set and her design characteristics.Case 103
The phrase “seamanlike way” in the definition Room refers to boat-handling that can reasonably be expected from a competent, but not expert, crew of the appropriate number for the boat.
2- Does 'room to keep clear' in this situation imply that immediate avoiding action need not be taken by the give way boat.
The rules do not expressly oblige a boat to act immediately on becoming a give way boat.
- She may delay taking action as long as she likes if she actually does keep clear.
- if there is contact, and the give way boat did not act promptly, then she will be unable to argue in a protest hearing that the fact of contact demonstrates that there was insufficient room to keep clear.
From case 88 (which is a different scenario)
"Keep clear means something more than avoid contact."
Is this point relevant to my question?
Case case 88
is not particularly relevant to your scenario. Case 88 is a scenario where the right of way boat is NOT required to give room to keep clear.
A better explanation of 'keep clear' is in Case 50Case 50

When a protest committee finds that in a port-starboard incident S did not change course and that there was not a genuine and reasonable apprehension of collision on the part of S, it should dismiss her protest. When the committee finds that S did change course and that there was reasonable doubt that P could have crossed ahead of S if S had not changed course, then P should be disqualified.
