Rules mainly define the set-up of the boats in each class. The Technical Rules are written with input from their classes. The classes vote on their own rules and send them to the board for approval. Safety To assure the highest level of safety, OSS only allows fully canopied (closed cockpit) boats which should meet or exceed the internationally accepted Lavin Guidelines. Each of the OSS races is covered by a large safety and rescue team. At each race, OSS has two of its own rescue helicopters (“Angel Ships”) with specially trained rescue jumper/divers. Their target is to come to the assistance of a boat, when needed, within 50 seconds of an accident. External links Offshore Super Series (OSS) website Motorboat racing
