Lots of good stuff here.

Other issues with a mid-course s/f line include having the line open vs. closed, interference with starts, etc. And as Matt mentioned, lots more to move if the wind shifts significantly.

As Harry eludes to here, the general trend I am seeing (at cat and mono events) is much, much more communication between the RC and the competitors. The competitors at all levels of the game are expecting this now.

VHF communication is one of the most effective means of getting this done (and don't kid yourself, even on 42 foot boats, they're not in the cabin listening to the boat radio, it's all done on handhelds). Competitors are expecting us to broadcast course info, our plans on how long until the next start, OCS boats, and even mid-race course change info. Of course, this is all backup to the visual signals which are still primary, but it really makes for much cleaner comunication.

We are still expected (at most events) not to answer questions directly, as this can be construed as outside help (by those who would choose to win by redress). The way we handle this is, if we hear a question that warrants an answer (most do), we make a general announcement to the fleet.

There are still many classes (including Hobie Cats) that do not allow VHF except for emergencies, but use of VHF for RC communication is a trend that seems to make sense, and would be nice if it starts to proliferate even more. The argument against VHF has always been about cost; this is a red herring, you can get a VHF for $100, new Hobie 16s are close to $10,000.
