41 OUTSIDE HELP
A boat shall not receive help from any outside source, except
(a) help for a crew member who is ill, injured or in danger ;
(b) after a collision, help from the crew of the other vessel to get clear;
(c) help in the form of information freely available to all boats;
(d) unsolicited information from a disinterested source, which may be another boat in the same race.
However, a boat that gains a significant advantage in the race from help received under rule 41(a) may be protested and penalized; any penalty may be less than disqualification .
