Offshore Challenge navigational rallies, including the Bass Strait Rally and the East Coaster, are competitive events (navigation, not racing) and so boats are grouped into classes and sub-categories. Details of classes and categories are issued for each event as it is announced.
Offshore Challenge expeditions, including The Kimberley Challenge, are non-competitive and so do not require performance classifications.
Minimum requirements for The Kimberley Challenge are that boats must:

|

The Offshore Challenge is designed for power boats, not yachts and sailing craft.
An important part of the Offshore Challenge Series is that each event is open to skilled amateurs and boating enthusiasts. The events are not designed for purpose-built offshore racing powerboats. If you are interested in offshore powerboat racing, check out the ASPAC-GT Series run by our associate company, Premier Ocean Events. www.premieroceanevents.com
Commercial entries are welcome. Boat manufacturers, boat dealers and any organisation in the marine industries wishing to enter should contact the organisers for details of special incentives, sponsorship arrangements and other joint promotional opportunities.
All craft must be registered with the relevant authority in their home state. Documentary proof of current registration will be required at pre-event scrutineering.
Each crew must consist of a minimum of two persons. The maximum number of crew, including the skipper, is six. All skippers must hold a current power boat license. All crew members who may take the helm at any stage during the event must also hold a power boat licence. Crew members under the age of 18 will require written consent of a parent or guardian in order to participate.
