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.

4.10.1

A passive Radar Reflector (that is, a Radar Reflector without any power) shall be provided

If a radar reflector is :

octahedral with triangular plates making up each pocket it must have a minimum diagonal measurement of 456 mm (18in).

octahedral with circular sector plates making up each pocket it must have a minimum diameter of 304mm (12in).

iii

not octahedral it must have a documented RCS (radar cross-section) of not less than 10 m2 at 0° elevation and be capable of performance around 360° in azimuth.

The minimum effective height above water is 4.0 m (13 ft).

The passive and active devices referred to in these notes and in 4.10.1 and 4.10.2 above are primarily intended for use in the X (9GHz) band

4.10.2

The most effective radar response from a yacht may be provided by an RTE (Radar Target Enhancer) which may be on board in addition to the required passive reflector. An RTE should conform to ISO 8729-2:2009. An RTE is strongly recommended.

MoMu1,2,3,4

The display of a passive reflector or the operation of an RTE is for the person in charge to decide according to prevailing conditions.

4.10.3

When available, a passive radar reflector in compliance with ISO8729-1:2010 will offer improved performance over earlier models and has a size typified by a cylinder of not more than weight 5kg, height 750mm and diameter 300mm.

4.10.4

S (3GHz) band radar is often used by ships in bad weather to complement X (9GHz) band radar. On S (3GHz) band a passive reflector offers about 1/10 the response obtained on the X (9GHz) band. Unless specifically designed to operate in the S(3GHz) band, an RTE will provide no response at all.

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.

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;

SECTION 5 - PERSONAL EQUIPMENT

5.01

Lifejacket

5.01.1

Each crew member shall have a lifejacket as follows:-

In accordance with ISO 12402 – 3 (Level 150) or equivalent, including EN 396 or UL 1180

Lifejackets manufactured after 1 January 2012 shall be in accordance with ISO 12402–3 (Level 150) and shall be fitted with:-

• an emergency light in accordance with either ISO 12402-8 or SOLAS LSA code 2.2.3.

• a sprayhood in accordance with ISO 12402-8.

• a full deck safety harness in accordance with ISO 12401 (ISO 1095) including a crotch or thigh strap (holding down device) as specified in ISO 12401 (ISO 1095).

• If of an inflatable type either

(a) automatic, manual and oral inflation or

(b) manual and oral inflation

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

5.01.4

The person in charge shall personally check each lifejacket at least once annually.

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

5.07
