Question 1
Yellow and Blue are sailing parallel courses. Rule 17.1 does not apply. Blue has adequate room to move away but nevertheless maintains a parallel course. After about 10 seconds Yellow luffs slowly and from the moment the luff starts, there is no longer any means of Blue avoiding Yellow. Blue luffs and there is contact. There is a Y flag. What should the call be?

Answer 1
When Blue has had an opportunity to keep clear but then sails so close to Yellow that any luff by Yellow will result in contact, Blue fails to keep clear and breaks rule 11. Penalize Blue.
