this........ there are a few states that all you need is the state's
"Guides & Packers" license. No uscg master or oupv needed on inland
waters for sailing lessons. Just think YMCA summer sailing lessons...
as an example

I'm guessing these "inland waters" are actually State regulated bodies
of water that are not covers by the US Inland rules. This would
include most of the lakes in New England, for example, where the camps
are.

These state rules are often quite different, and will include things
like "human powered vessels have right of way over sailboats," which
are totally ignored by the ColRegs or Inland Rules.
