good day you all

new on the forum; trying to get opinions on the other part of the world.

what puzzles me is the "proper course" inside the "mark room"

at a windward mark, boat W inside boat, L outside, approaching a mark to be left on port (left) by tacking at the mark; rule 18,2 applies.

For that, L give mark room to W. OK, fine.

at the mark, W does NOT tack to round the mark, but keeps going straight

with old rules, W was entitled to do so.i.e. was not obliged to tack and round the mark

my question: with new rules, and with the new concept of proper course inside the "mark room", W MUST keep its proper course (meaning MUST tack and round the mark, as per proper course), or  may keep going straight as per old rules?

thank

As long as she keeps clear under rule 11, W can keep L pinned past the mark.  L may pinch and push W up, subject to rules 16 and 17 (if applicable).  Meanwhile the rest of the fleet go charging past.

There is no rule corresponding to rule 18.4 Gybing, that requires and inside boat to tack promptly.

W only needs to observe her proper course at the mark if she wants exoneration for breaking rules 10, 11, 12, 13, 15 or 16.

For what happens next see ISAF Q&A 2009-17.

Thank you for your clear reply.

You state:

There is no rule corresponding to rule 18.4 Gybing, that requires and inside boat to tack promptly

that was exactly my doubt about "proper course",

in 18.4 the proper course is explicit, in the rule

18.2, the proper course is hidden in the definition.of "mark room" (proper course at the mark)

anyway, you confirm that W is not asked to follow the proper course of the "mark room" i.e. W can pin L, under  limitations of rule 11

thank you again.
