pretty vague, even for a bill. Define "supervision" as it pertains to how many people can the adult supervise at one time? An Opti fleet? 2 vessels?

And what proximity constitutes "supervision"? A coach boat? From shore?

So since the Steeplechase is not put on by a "school", my 17 year old can't sail it without me following?

I honestly didn't think this (minors sailing without supervision) was such a problem. The jet-ski group, on the other hand, seems relatively rife with minors doing dumb things... but my evidence is only anecdotal and possibly jaded a bit.
