In the same way that all rules are enforced in our self-policing sport. If someone thinks a boat has broken it, they should protest. The PC will then make a judgement on the evidence presented. 

As long as they comply with the definition of start, they're fine. And given the layout of the ISC startline, on a flooding tide like that you can't actually comply with the definition on starboard - you have to cross the line on port.

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.

Fairly common however for coastal clubs to use fixed navigation marks as the ODM of club lines, which shift in the tide.

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.

Easier for SI writers to include an SI similar to the Island's

Yes.

And for the white group, we found Alpha (the ODM) was generally within 1bl of the line, and as the only time you want to be out at that end was starting to the west on the ebb, it's not really a problem as the tide takes you west pretty quickly. Trying to muck about being clever isn't really worth it - far better to concentrate on Cowes week rule 1 - on the line in clear air.

Easier said than done sometimes: and consider a handicap race with Oppies and Flying Dutchmen...

Every now and then one comes across an appeal that really doesn't seem enormously helpful to promoting fairer racing... Think that's one of them!
