20.During swimmer changeover, swimmers will tag at least 10 metres from the support boat in a visible manner (above water surface).

21.In the case of a shark sighting, the support boat skipper MUST report the sighting immediately to race radio on Channel 74.

Vessels are to remain in their location until the Race Director advises it is safe for swimmers and paddlers in that zone to re-enter the water and continue with the event without disqualification. Solo swimmers, you can remain in the water but do so at your own risk. If you leave the water, your swim will be regarded as abandoned / aborted in line with FINA rules and will not be recorded as an official solo crossing.

It is the skipper’s responsibility to make themselves aware of the regulations and requirements related to travelling to Rottnest Island. (See www.dot.wa.gov.au)

28.Support boats MUST NOT make way astern. This means they must not move backwards. To avoid danger (to a vessel, a swimmer, a paddler, etc.) a skipper is permitted to use astern (reverse) thrust – BUT ONLY TO STOP OR SLOW THE VESSEL’S FORWARD WAY. The vessel MUST NOT make way astern (i.e. move backwards) under any circumstances. If you need to stop or slow the vessel’s forward way, they must ensure it is safe to do so (i.e. no swimmer or paddler immediately behind the vessel).

38.Support boats must assemble in clearly designated holding areas to the north and south of the swim channel. Support boat skippers will be notified just prior to their swimmer wave by VHF Channel 74 and will proceed to join up with swimmer at the 1000 metre mark. Swimmers and paddlers cannot be dropped off at the start line by their support boat. Please note the 1000m from the start line is a support boat exclusion zone.

39.If a swimmer is unaccompanied by their support boat at the 1500 metre mark (TAMS tug boat), they are instructed to swim to the moored TAMS tug boat and tread water. Port to Pub staff will contact swim base to notify them of your location and that you are awaiting support vessel. Swimmers may re-enter the event on the arrival of their support boat. Swimmers may tread water for 20 minutes and, if no support boat arrives the swimmer must withdraw from the event and return to the beach.

40.If a support boat has not located its swimmer by the 1500 metre mark (TAMS Tug), the boat skipper must advise Swim Base by marine radio (VHF CH74) and await further instructions.
