Pet peeve (doesn't quite rank with 'crash tack'):  there is no such thing as a 'passing mark'. 

Appendix B has the concept of passing a mark [grin]. Agreed the term is not used outside the appendix, but it is useful in this context. I must admit I'm not entirely clear what it brings to Appendix B, but that's maybe because I've never been involved in board competition.
 
I notice that it's used in the defined term 'rounding or passing' which the boards use instead of a zone in rule 18.

Why would you want to set a default of  rounding all marks (although sometimes SI do this through carelessness)?


Consider a course like this, which is quite useful for round the cans handicap racing.



If a careless or hurried amateur race team sets the starboard rounding mark a bit to the right of the rhumb line between windward and leeward marks, and the leeward mark is not defined as a rounding mark...
I see what you are driving at.

My preference would be to write in the SI Course:  Red Mark is a rounding mark, or to be rounded to port, rather than making a default.

If you're writing SIs for an event completely agree, but consider club racing at a typical UK club like mine. We have a standard set of SIs to cover the whole season, and courses are set on the day. Its a bit impractical to edit a set of SIs and publish them between 10am when you set the course and 10:24 when the sequence starts!

As for the situation where you get out there and the wind goes round 90 degrees and you have to hastily change the course... Mind you if a course has to be completely reset in 5 minutes flat out on the water the sensible RO makes sure the new one is very simple - 3 or 4 marks and all port rounding, otherwise some folks are bound to get lost.

They use the Alzheimers Prevention Rule at Redoubt.. Make us poor old b**tards use as many of the 9 buoys as often as possible as a memory test, it shouldn't be allowed. there should only be three marks to remember in any course.

It's a very long time since I was involved in club racing but I remember this issue coming up from time to time. If travelling from mark A to mark C via mark B when B is off to starboard from the course between A and C, the norm would be to leave B to port.  If the RO specifies a loop round B, that means leaving B to stbd. 

Back in the day, savvy helms would sail direct from A to C, thereby leaving B to stbd and satisfying the requirements of the course. Is that not the case today?

Why would you want a mark to be looped, unless you happen to be a boat repairer short of work?

No-one would want a mark to be looped, but sometimes circumstances force it.

See the situation JimC described in his post on 11 Dec 17, with a laid mark that could be accidentally laid on the 'wrong' side of the line joining the previous and the next mark.

Likewise, in Sydney, we have a number of permanently laid racing marks for use by all clubs which the port authority requires to be rounded only to starboard:  if you've got one of those on a wing where it would naturally be rounded to port, then it has to be looped to starboard.

Sorry that's complete rubbish. looping marks is daft and pointless. If the course says pass a mark to Starboard and you have to loop it to pass that side then ignore it completely and you'll still be passing it to Starboard.......

RYA appeal 1985/4 applies.

http://www.rya.org.uk/SiteCollectionDocuments/Racing/RacingInformation/RacingRules/RYA%20Case%20Book%2003.17.pdf#page68

When a race committee intends a mark to be looped, the mark must be identified as a rounding mark. When the sailing instructions do not do so, or when they are ambiguous, a boat may elect not to round a mark when she can still leave it on the required side and in the correct order.
