PART 4
OTHER REQUIREMENTS WHEN RACING
Part 4 rules apply only to boats racing. However, rule 55 applies at all times when boats are on the water. 40 PERSONAL FLOTATION DEVICES When flag Y is displayed with one sound before or with the warning signal, competitors shall wear personal flotation devices, except briefly while changing or adjusting clothing or personal equipment. Wet suits and dry suits are not personal flotation devices. 41 OUTSIDE HELP A boat shall not receive help from any outside source, except (a) (b) (c) (d) help for a crew member who is ill, injured or in danger; after a collision, help from the crew of the other vessel to get clear; help in the form of information freely available to all boats; 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. 42 42.1 PROPULSION Basic Rule Except when permitted in rule 42.3 or 45, a boat shall compete by using only the wind and water to increase, maintain or decrease her speed. Her crew may adjust the trim of sails and hull, and perform other acts of seamanship, but shall not otherwise move their bodies to propel the boat.
