ABSTRACTS BY RULE NUMBER 40-54  

PART 4 – OTHER REQUIREMENTS WHEN' RACING
Rule 41, Outside Help

CASE 100
When a boat asks for and receives tactical racing advice she receives outside help, even if she asks for and receives it on a public radio channel.

Rule 42, Propulsion

CASE 8
While reaching at good speed, a boat does not break rule 42 when her helmsman, anticipating and taking advantage of waves generated by a passing vessel, makes helm movements timed to the passage of each wave. This is not sculling but using the natural action of the water on the hull.
CASE 69
Momentum of a boat after her preparatory signal that is the result of being propelled by her engine before the signal does not break rule 42.1.

Rule 43.1(a), Competitor Clothing and Equipment

CASE 89
A competitor may not wear or otherwise attach to his person a beverage container.

Rule 44.1, Penalties at the Time of an Incident: Taking a Penalty
Rule 44.2, Penalties at the Time of an Incident: One-Turn and Two- Turns Penalties

CASE 19
An interpretation of the term ‘damage’.
CASE 99
The fact that a boat required to keep clear is out of control does not entitle her to exoneration for breaking a rule of Part 2. When a right-of-way boat becomes obliged by rule 14 to ‘avoid contact . . . if reasonably possible’ and the only way to do so is to crash-gybe, she does not break the rule if she does not crash-gybe. When a boat’s penalty under rule 44.1(b) is to retire, and she does so (whether because of choice or necessity), she cannot then be disqualified.
CASE 107
A boat that is not keeping a lookout may thereby fail to do everything reasonably possible to avoid contact. Hailing is one way that a boat may ‘act to avoid contact’. When a boat’s breach of a rule of Part 2 causes serious damage and she then retires, she has taken the applicable penalty and is not to be disqualified for that breach.
CASE 108
When taking a penalty after touching a mark, a boat need not complete a full 360°turn, and she may take her penalty while simultaneously rounding the mark. Her turn to round the mark will serve as her penalty if it includes a tack and a gybe, if it is carried out promptly after clearing and remaining clear of the mark and other boats, and when no question of advantage arises.

Rule 46, Person in Charge

CASE 40
Unless otherwise specifically stated in the class rules, notice of race or sailing instructions, the owner or other person in charge of a boat is free to decide who steers her in a race, provided that rule 46 is not broken.

Rule 48, Fog Signals and Lights

CASE 109
The IRPCAS or government right-of-way rules apply between boats that are racing only if the sailing instructions say so, and in that case all of the Part 2 rules are replaced. An IRPCAS or government rule may be made to apply by including it in the sailing instructions or in another document governing the event.

Rule 49, Crew Position

CASE 4
A competitor may hold a sheet outboard.
CASE 36
Positioning of crew members relative to lifelines.
CASE 83
Repeated sail trimming with a competitor’s torso outside the lifelines is not permitted.

Rule 50.3, Setting and Sheeting Sails: Use of Outriggers

CASE 4
A competitor may hold a sheet outboard.
CASE 97
A jockey pole attached to a spinnaker guy is not an outrigger.
