1.2.3 All craft must be capable of maneuvering ahead and astern, while also being able to demonstrate neutral position on a least one (1) of the main propulsion engine drive lines, operated by controls at the helmsmen’s position. Boats with more than one (1) shaft shall be capable of maintaining a straight course in a set direction on any one (1) propeller.

1.2.4 Fuels are limited to petroleum based fuels. Non-petroleum based fuels or additives such as nitrous oxide or oxygen, designed to increase horsepower are prohibited.

1.2.5 Any propulsion utilizing the thrust of water is allowed if it meets all the safety requirements.

1.2.6 Diesel engines shall be allowed (8) pounds of non-petroleum based fuel on board, per engine, which can only be used in the start-up procedure.

1.3 Canopies

Unlimited registered race boats are required to have canopies.

1.3.1 All canopied boats are recommended to comply with the latest canopy design and technology. Contact the boat manufacturer for their canopy standards. Any damage to canopies must have a notarized certified letter from a manufacturer of canopies authorizing the continued use in a race.

1.3.2 Non-compliance – RWO has the authority to deny entry to any race boat subject to these rules that has non-compliant cockpit safety systems.

1.4 Hull and Deck

1.4.1 All race boats shall have a minimum overall length of forth (40’) feet and a maximum length of fifty-five (55’) feet measured on the centerline of the hull between perpendiculars at the extreme bow and stern. All measurements are taken while the boat is ashore. The keel line shall be level amidships. The stern shall be defined as the transom, joining the extremities of the hull on which the outboard motor or driveline is attached. Any extending parts, rub rails, fenders, stabilizing and trim tabs, rudders or attached molded platforms are not to be included. Overall hull lengths shall be rounded off within a six (6) inch tolerance.

1.4.2 Any underwater hull design shall be eligible if safe and manageable in open sea conditions. Three (3) point “Hydro-Design” is not an offshore design which is to be considered safe and manageable in an open sea condition.

1.4.3 Through deck fuel fills are mandatory as specified by United States Coast Guard regulations.

1.4.4 Hulls utilizing adjustable planes, such as hydrofoils, are not legal for competition. All designs are subject to final approval by the technical committee. Tunnel Tabs are allowed.

1.4.5 Engine compartments must have rigid covers.

1.4.6 Engine and fuel compartments must be adequately ventilated and must meet United States Coast Guard regulations.

1.4.7 Fuel must be carried in tanks which are suitably secured and vented. Boats many not transfer fuel during the race, except by means of properly installed fuel lines. Manual transfer of fuel from one tank to another, while the engines are shut down, will be permitted in boat installations where multiple tanks are utilized.

1.4.8 Rails (6” maximum height) or hand holds must be installed fore and aft and should enable the crew to proceed from the cockpit to the entire deck length, for the purpose of working on the craft in adverse sea connections.

1.4.9 Navigational electronics, excluding auto-helm, are permitted.

1.4.10 A single point lifting harness is mandatory to race terms utilizing the on-site promoter’s crane. Non-conformers must make their owner launching arrangement.
