Quote:-

Mark-Room Room for a boat to sail to the mark, and then room to sail her proper course while at the mark. However, mark-room does not include room to tack unless the boat is overlapped to windward and on the inside of the boat required to give mark-room.

"To" has no special definition, so it's from the "mark room circle" to the mark. It's difficult to interpret as "sailing high then gybing" because it doesn't refer to "proper course". It's a bit like going from Land's End to John O'Groats - via Amsterdam.

In fact the standard interpretation of the first part of "mark room - to the mark - is that mark room entitles a boat to occupy a narrrow corridor, a little larger than the the width of the hull and equipment - which in the case of a boat flying a symetrical spinnaker is probably about a boat length in width, taking account of pole + hull + boom - from the point of entry to the required side of the mark.

If a boat sails outside of this corridor then they will have towork hard to  convince the jury that they are taking mark room.

If at point of entry a gybe is necessary to get to the mark it is best t do it immediately.

If a gybe is necessary to round the mark  it is best to do so at the mark.

Mark-room to sail to the mark may include room to gybe, that is room to handle and deploy your sails and spars in a seamanlike way, if gybing is the seamanlike thing to do, but only as long as you do not change course off your course to the mark.

C'mon Gordon, the rules don't say anything like that.

That's just how the rules drafters and nearly everyone in the known universe says they should be interpreted.

Nope:  just make them come up in a pop-up box 'on-hover'.

For a hard copy print version having them on the very last page as they are at present is the most accessible option.

If you were in really light winds in an RS400 then "sailing to the mark" would mean sailing a hot angle, and in our case a gybe

( just having a go at  winding up Jim C on the 400s optimised drag.. .)

What'dya think guys? Hot street legal ? or drop and run to the mark?

If sailing your proper course at the mark includes a gybe, then the boat entitled to mark room is to be given enough room to do so promptly in a seamanlike manner... which is not much for an Oppy sailing on a small pond and quite a lot for a 60 footer at an offshore mark in a strong breeze!

Personally I find it easier to try and stay out of trouble and minimise any loss from getting stuck on the outside.

The other way is of course to try and sail tactically and cut back inside or not let them get the overlap in the first place. Difficuly I grant you when you might be dead running with a assymetric sailing the angles.

Thinking triangles and sausages here.

Most cats do not go deep to drop; when sailing with a crew; as soon as the halyard is tripped, I'm heading up and getting some heat on.
