R29.1 Individual Recall says nothing about a boat having crossed the Start Line from pre start to course side , merely that "part of the hull is on the course side...." at the Starting Signal.
So what about the scenario where a boat is arriving late at the start area from the COURSE side for a (very) late start, and is well up the course side heading to the line, obviously intending to race, but has never been in the "race area" . Should there be an individual recall if the boat has never been on the prestart side of the line or its extension and is some way up the course?
Secondly, what about a situation where a boat has crossed the line incorrectly with the previous class, so at its correct start it is well up (5 mins) the course side? Should there be an individual recall?
2. possibly but probably better to just put DNS
The problem with doing the correct thing, signalling the recall is that the boats look to see who was over and boats may return thinking it was them.
Possibly better to do nothing, and as the boats were obviously over, vigorously challenge any redress call (if any), saying they must have been aware they were over.
