If required by the policies of the Class Association or the organizers,
require that a boat intending to protest shall, immediately after finishing,
in addition to the requirements of rule 61.1(a), inform the Race
Committee boat at the finishing line of her intention to protest and give

note such reports on its results log.
Support Boats (RRS L23)

Some regattas will provide a set of regulations for support boats and
support persons. Otherwise, except when participating in rescue
operations, team leaders, coaches, parents and other support personnel
shall be required to stay outside areas where boats are racing from the
time of the preparatory signal for the first fleet to start until all boats have
finished or retired or the Race Committee signals a postponement or an
abandonment of all fleets. The areas where the boats are racing can be
defined as the area inside the course and within a distance specified by
the RC of any mark, lay line, starting line, finishing line or any area where
any boat that is racing is sailing or may sail.
