SECTION 1 - FUNDAMENTAL AND DEFINITIONS

1.01

Purpose and Use

1.01.1

It is the purpose of these Special Regulations to establish uniform minimum equipment, accommodation and training standards for monohull and multihull yachts racing offshore. A Proa is excluded from these regulations.

1.01.2

These Special Regulations do not replace, but rather supplement, the requirements of governmental authority, the Racing Rules and the rules of Class Associations and Rating Systems. The attention of persons in charge is called to restrictions in the Rules on the location and movement of equipment.

1.01.3

These Special Regulations, adopted internationally, are strongly recommended for use by all organizers of offshore races. Race Committees may select the category deemed most suitable for the type of race to be sailed.

1.02

Responsibility of Person in Charge

1.02.1

The safety of a yacht and her crew is the sole and inescapable responsibility of the person in charge who must do his best to ensure that the yacht is fully found, thoroughly seaworthy and manned by an experienced crew who have undergone appropriate training and are physically fit to face bad weather. He must be satisfied as to the soundness of hull, spars, rigging, sails and all gear. He must ensure that all safety equipment is properly maintained and stowed and that the crew know where it is kept and how it is to be used. He shall also nominate a person to take over the responsibilities of the Person in Charge in the event of his incapacitation.

1.02.2

Neither the establishment of these Special Regulations, their use by race organizers, nor the inspection of a yacht under these Special Regulations in any way limits or reduces the complete and unlimited responsibility of the person in charge.

1.02.3

Decision to race -The responsibility for a yacht's decision to participate in a race or to continue racing is hers alone - RRS Fundamental Rule 4.

4.20.5

Liferaft Servicing and Inspection

MoMu0,1,2

IMPORTANT NOTICE Recent evidence has shown that packaged liferafts are vulnerable to serious damage when dropped (e.g. from a boat onto a marina pontoon) or when subjected to the weight of a crew member or heavy object (e.g. an anchor). Damage can be caused internally by the weight of the heavy steel CO2 bottle abrading or splitting neighbouring layers of buoyancy tube material. ISAF has instituted an investigation into this effect and as an interim measure requires that every valise-packed liferaft shall have an annual certificate of servicing. A liferaft should be taken for servicing if there is any sign of damage or deterioration (including on the underside of the pack). Persons in charge should insist on great care in handling liferafts and apply the rules NO STEP and DO NOT DROP UNLESS LAUNCHING INTO THE SEA.

MoMu0,1,2

Certificates or copies, of servicing and/or inspection shall be kept on board the yacht. Every SOLAS liferaft and every valise-packed liferaft shall have a valid annual certificate of new or serviced status from the manufacturer or his approved service station.

MoMu0,1,2

A liferaft built to OSR Appendix A part I ("ORC") packed in a rigid container or canister shall either be serviced annually or may, when the manufacturer so specifies, be inspected annually (not necessarily unpacked) provided the yacht has on board written confirmation from the manufacturer's approved service station stating that the inspection was satisfactory.

MoMu0,1,2

A liferaft built to OSR Appendix A part II ("ISAF") packed in a rigid container or canister shall either be serviced annually or may, when the manufacturer so specifies, have its first service no longer than 3 years after commissioning and its second service no longer than 2 years after the first. Subsequent services shall be at intervals of not more than 12 months.

MoMu1,2

A liferaft built to ISO 9650 Part 1 Type Group A, packed in a rigid container or canister shall be serviced in accordance with the manufacturer’s instructions but NOT less frequently than every three years

MoMu1,2

A liferaft built to ISO 9650 Part 1 Type Group A packed in a valise shall be inspected annually by an approved manufacturer’s agent and serviced in accordance with the manufacturer’s instructions but NOT less frequently than every three years.

4.26

Storm & Heavy Weather Sails

4.26.1

Design

it is strongly recommended that persons in charge consult their designer and sailmaker to decide the most effective size for storm and heavy weather sails. The purpose of these sails is to provide safe propulsion for the yacht in severe weather -they are not intended as part of the racing inventory. The areas below are maxima. Smaller areas are likely to suit some yachts according to their stability and other characteristics.

4.26.2

High Visibility

Every storm jib shall either be of highly-visible coloured material (e.g. dayglo pink, orange or yellow) or have a highly-visible coloured patch at least 50% of the area of the sail (up to a maximum diameter of 3m) added on each side; and also that a rotating wing mast should have a highly-visible coloured patch on each side. A storm sail purchased after January 2014 shall have the material of the body of the sail a highly-visible colour.

4.26.3

Materials

aromatic polyamides, carbon and similar fibres shall not be used in a trysail or storm jib but spectra/dyneema and similar materials are permitted.

it is strongly recommended that a heavy-weather jib does not contain aromatic polyamides, carbon and similar fibres other than spectra/dyneema.

4.26.4

The following shall be provided:-

sheeting positions on deck for each storm and heavy-weather sail;

for each storm or heavy-weather jib, a means to attach the luff to the stay, independent of any luff-groove device. A heavy weather jib shall have the means of attachment readily available. A storm jib shall have the means of attachment permanently attached;

Storm and heavy weather jib areas shall be calculated as: (0.255 x luff length x (luff perpendicular + 2 x half width))* To apply to sails made in January 2012 and after.

when a storm trysail is required by OSR 4.26.4 (g) it shall be capable of being sheeted independently of the boom with trysail area not greater than 17.5% mainsail hoist (P) luff length x mainsail foot length (E). The storm trysail area shall be measured as (0.5 x leech length x shortest distance between tack point and leech). The storm trysail shall have neither headboard nor battens, however a storm trysail is not required in a yacht with a rotating wing mast which can adequately substitute for a trysail. The method of calculating area applies to sails made in January 2012 and after.

Extract File Only MoMu 3

if a storm trysail is required by OSR 4.26.4 (g) the yacht's sail number and letter(s) shall be placed on both sides of the trysail (or on a rotating wing mast as substitute for a trysail) in as large a size as practicable;

Notes: ISO 12402 requires Level 150 lifejackets to be fitted with a mandatory whistle and retro-reflective material. Also, when fitted with a safety harness, ISO 12402 requires that this shall be the full safety harness in accordance with ISO 12401. Any equivalent lifejacket shall have equal requirements.

Persons of larger than average build are generally more buoyant than those of average build and so do not require a lifejacket with greater levels of flotation. Wearing a Level 275 lifejacket may hamper entry into liferafts.

fitted with either a crotch strap(s) / thigh straps or a full safety harness in accordance with ISO 12401,

Note: The function of lifejacket crotch/thigh straps is to hold the buoyancy element down. A crew member before a race should adjust a lifejacket to fit then retain that lifejacket for the duration of the race. Correct adjustment is fundamental to the lifejacket functioning correctly.

fitted with a lifejacket light in accordance with SOLAS LSA code 2.2.3 (white, >0.75 candelas, >8 hours),

if inflatable have a compressed gas inflation system,

if inflatable, regularly checked for gas retention,

compatible with the wearer's safety harness,

clearly marked with the yacht's or wearer's name,

It is strongly recommended that a lifejacket has:

a splashguard / sprayhood See ISO 12402 – 8,

MoMu1,2,3,4

a PLB unit (as with other types of EPIRB, should be properly registered with the appropriate authority)

MoMu1,2,3,4

if of a gas inflatable type, a spare cylinder and if appropriate a spare activation head

MoMu1,2,3,4

Safety Harness and Safety Lines (Tethers)

MoMu0,1,2,3

5.02.1

Each crew member shall have a harness and safety line that complies with ISO 12401 or equivalent with a safety line not more than 2m in length.

MoMu0,1,2,3

Harnesses and safety lines manufactured prior to Jan 2010 shall comply with either ISO 12401 or EN 1095.

Harnesses and safety lines manufactured prior to Jan 2001 are not permitted.

Warning it is possible for a plain snaphook to disengage from a U bolt if the hook is rotated under load at right-angles to the axis of the U-bolt. For this reason the use of snaphooks with positive locking devices is strongly recommended.

MoMu0,1,2,3

5.02.2

At least 30% of the crew shall each, in addition to the above be provided with either:-

MoMu0,1,2,3

a safety line not more than 1m long, or

MoMu0,1,2,3

a mid-point snaphook on a 2m safety line

MoMu0,1,2,3

5.02.3

A safety line purchased in January 2001 or later shall have a coloured flag embedded in the stitching, to indicate an overload. A line which has been overloaded shall be replaced as a matter of urgency.

MoMu0,1,2,3

5.02.4

A crew member's lifejacket and harness shall be compatible

MoMu0,1,2,3

5.02.5

It is strongly recommended that:-

MoMu0,1,2,3

static safety lines should be securely fastened at work stations;

MoMu0,1,2,3

ISAF OSR 5.02.5 b) is amended to read: A harness shall be fitted with a crotch strap or thigh straps.

MoMu0,1,2,3

to draw attention to wear and damage, stitching on harness and safety lines should be of a colour contrasting strongly with the surrounding material;

MoMu0,1,2,3

snaphooks should be of a type which will not self-release from a U-bolt (see OSR 5.02.1(a)) and which can be easily released under load (crew members are reminded that a personal knife may free them from a safety line in emergency);

MoMu0,1,2,3

a crew member before a race should adjust a harness to fit then retain that harness for the duration of the race.

MoMu0,1,2,3

5.02.6

Warning - a safety line and safety harness are not designed to tow a person in the water and it is important that the shortest safety line length possible be used with a harness to minimise or eliminate the risk of a person's torso becoming immersed in water outside the boat, especially when working on the foredeck. 1m safety lines or the midpoint snaphook on a 2m line should be used for this purpose. The diligent use of a properly adjusted safety harness and the shortest safety line practicable is regarded as by far the most effective way of preventing man overboard incidents.

5.04

Foul Weather Suits

it is recommended that a foul weather suit should be fitted with marine-grade retro-reflective material, and should have high-visibility colours on its upper parts and sleeve cuffs. See OSR 4.18

A buoyant watertight flashlight, one shall be supplied to each crew member.

MoMu0

RORC recommends that each crewmember carries in a pocket a combination torch/strobe light, not only are these devices useful as a personal torch but they are also valuable in aiding location in a man overboard situation.
