SER and ISAF Special Regs


US Sailing Seeks Recommendations for Safety Equipment Requirements – July, 2015

US Sailing’s Safety at Sea Committee has conducted an overhaul of ISAF’s Offshore Special Regulations (OSR), which describes the gear required to be used on sailboats when racing in most local and offshore races. The Safety Equipment Requirements (SER) document is intended to be used by race organizers, owners and boat inspectors.

The SER sub-committee has completed an initial list of equipment and boat characteristics that will serve the needs of the majority of coastal and offshore racers in 2014.

The key differences between the Safety Equipment Requirements (SER) and the International Sailing Federation (ISAF) OSRs are as follows:

1. The requirements are easier for yacht owners and pre-race inspectors to understand.

2. The requirements are self-contained and do not refer to external documents.

3. The number of race categories has been reduced from seven to three: Nearshore, Coastal, and Ocean. Race organizers can then add or delete gear requirements based on the nature of their individual races.

4. The requirements are more specific about certain pieces of gear that lacked definition in the OSRs.

5. The OSRs contained both recommendations and requirements which proved confusing to users, and which increased the size of the document. The recommendations have been removed from the new version.

6. The requirements are far more compact, and can easily be included in their entirety in a Notice of Race or on a yacht club website.

Chuck Hawley, US Sailing’s Safety at Sea Committee Chairman:

“One of the functions of the Safety at Sea Committee is to promote equipment requirements that are appropriate for the conditions, easily verified, and not excessive. I believe that the new SERs meet those criteria, and will serve offshore sailors well. We encourage all Organizing Authorities to use them, edited if the local conditions warrant, so that races are sailed under consistent equipment rules.”

As with any standards document, the USSER will be modified over time. Download the new requirements.
