Inner Distance Mark

Originally posted by blueboy  But there's no similar wording in (say) the Cowes Week Black Group SIs, despite it being common on the RYS line for the ODM to be several boat lengths off the line. Not necessary for this year as the black group line had nothing to do with the RYS line - it (black group line) was defined as between the committee boat and the ODM at the southern end.

Oh dear I see I was living in the past on that one but in my defence, gentlemen prefer to sail in White Group. What I was trying to get at were starts off the full-length RYS line where the ODM is a fixed navigation mark that moves several boat lengths in the current. Although, I guess as it is mostly used for west-going starts on the ebb, when the mark will shift to the west, the issue doesn't arise that often.

How exactly can this be enforced?

It doesn't solve the problem either, as a STBD boat might touch the line well offshore then 'ferry glide' along the line right into the shore.
