What the charter companies want is your money. If you can anchor,
and motor a bit, then you can take out one of their boats.

ever see anyone on a charter that wasn't motoring 95% to 100% of the time?

Except for the flogging charter boat sails take when someone tries for half an
hour "to sail", charter boat sails are still brand new when the boat comes out
of service.

Charter boat sailing is to sailing as sitting on a park bench is to motorcycle
riding.
