If a closed start/finish line isn't an obstruction what is it?
Navigable waters. I understand by obstruction something you cannot physically navigate through.
Windward boat on the DW leg has placed them selves in a bad spot.
An obstruction is something that is defined as such.
A finish line can be defined as an onstruction on the down wind leg of of a W/L race; areas of water (say defence firing range) can be defined as onstructions. It does not HAVE to be something you cannot sail thru, but it is somethijng you are not
allowed to sail thru.
