Essential Safety On Board as Required by the Offshore Special Regulations

Whether you are getting your boat ready for the racing season, or just want to ensure that your boat is well prepared for cruising, the World Sailing Offshore Special Regulations are a must read.

Published every two years, the Offshore Special Regulations (OSR) cover in great detail the required equipment and structural features for both mono and multihulls, as well as personal equipment and training that a yacht must comply with before it is allowed to race. Much of
the OSR content can also be applied to cruising vessels to make them as seaworthy and safe as possible for the skipper and crew.

World Sailing recognises that not all racing is at the same level. Consequently, they split offshore sailing in to 5 categories, with differing levels of equipment required for the safe participation in each:

 

Category 0 - Trans-oceanic races, where boats must be completely self-sufficient for extended periods of time and capable of withstanding heavy storms and serious emergencies.

Category 1 - Races of long distance and well offshore, where boats must be completely self-sufficient for extended periods of time and capable of withstanding heavy storms and serious emergencies.

Category 2 - Races of extended duration not far from shore where a high degree of self- sufficiency is required.

Category 3 - Races across open water, most of which is relatively protected or close to shore.

Category 4 - Short races, close to shore in protected waters normally held in daylight.

 

To help you easily comply with most of the Regulations that cover safety on board, we have taken the key elements of the two relevant sections and highlighted the essential products required for them, along with which Category of race they apply to.
