Boat skippers control all matters related to their boats and are responsible for the safety and well-being of their swimmer/s, paddler/s, and support crew. Skippers must, at all times, follow event rules and be aware of other event participants in the water and on race vessels.

Skipper responsibilities include:

Course
The skipper sets the course with weather and ocean conditions in mind. It is recommended to plan for and chart the course prior to event day understanding that changes might need to be made on the day.

Swimmer safety
Skippers must always maintain an unobstructed view of their swimmer/s and paddler (if applicable).

Registration
Skippers must have completed Port to Pub registration. Skippers must supply a mobile phone number that is kept on throughout the event to allow event officials to contact them if required.

Regulations
Skippers must be aware of the regulations and requirements related to travelling to Rottnest Island.

Licences
Skippers must have a valid Recreational Skipper Qualification.

Insurance
It is recommended that support vessels have adequate cover for the risk present on event day.

Sea Rescue
It is recommended that skippers become members of Fremantle Sea Rescue.

Transport protocols
Follow transport protocols on your way to the event. It will be dark, so have correct lighting. Allow plenty of time due to boat traffic.

Positioning
The support boat should be positioned in one of the holding zones approximately 30 minutes before the swimmer’s allocated start wave.

Speed & Distance
All boats need to keep within a 6-knot speed limit and stay ~10 metres from their swimmer (or slower swimmer if supporting tandem swimmers).

Withdrawals
Boats withdrawing from the event must be at least 200 metres from the race channel and main fleet before increasing boat speed past 8 knots.

Swimmer changeovers
Boats with single engines must be in neutral during swimmer changeovers. Boats with twin engines must switch both engines off completely during swimmer changeovers. Boats must not circle towards other swimmer paths during pickups.

Manoeuvring safely
Boats should not go astern at all; however, skippers can use reverse thrust to stop the forward way of their boat to avoid swimmer, paddler, or vessel collision. This must be done in a controlled manner with the skipper checking that it is all clear behind the boat before acting.

On boat communication
Swimmers and boat crew must be aware of the vessel’s engine status and ensure the propeller is not in use during swimmer changeovers.

Commercial vessel traffic
Support craft will be advised of commercial vessels expected to pass through the field by Fremantle Sea Rescue via radio communications and Fremantle Sea Rescue vessels on the water.

Incident reports
Skippers must submit a marine incident report form to the DoT Marine Safety Section within 48 hours of an incident occurring. It is the skipper’s responsibility to submit the relevant reports to the DoT.

It is extremely important important to prepare the support boat for race day — this includes checking that everything on board is current, up-to-date, and in working order.

Licence & Registration
All support boats and tenders must have a valid licence and registration. It is recommended that support boats be 5-10m in length and must not be smaller than 3.75m in length. Vessels that are 10m or longer are required to stay on the extremities of the fleet (north or south) but remain south of the northern boundary at all times. Tenders should be 3.1m or less in length with a motor not exceeding 5hp.

Boat occupancy
Refer to DoT requirements on boat size and occupants or your Boat Builder’s Plate to determine how many people are legally permitted on board. Your boat must be licensed to carry your whole team (e.g., skipper, swimmer/s, paddler/s, spotter, and/or other support crew).

Safety equipment
Support boats must be equipped with mandatory marine safety and emergency equipment as per the WA Navigable Water Regulations 1958.

Propeller guard
Port to Pub recommends that all vessels have propeller guards installed.

It is essential that support boats carry mandatory safety equipment. If the boat fails to meet DoT standards, the swimmer/team may face disqualification.

Holding areas
Support boats are required to wait in a holding area prior to their swimmer’s wave start. Boats can choose to wait in the ‘North’ or ‘South’ holding areas:

• ‘North’ is 600m north of the start channel and adjacent the railway pedestrian bridge
• ‘South’ is 600m south of the start channel and adjacent the Coast Port Beach restaurant

Paddlers are to assemble at the buoys 500 metres offshore five minutes prior to wave start at the agreed north or south holding area (for 25km paddlers the north holding area is recommended).

Misplaced (unaccompanied) swimmers
The Official ICON VESSEL will be anchored at the 1500 metre mark. Unaccompanied swimmers must swim to this vessel to tread water and must not proceed any further without their support boat.

If the swimmer has not been joined by their support boat after 20 minutes, the swimmer will be returned to Leighton Beach. The same treatment applies to swimmers that have located their paddler (when applicable) but not their support boat.

Once the support boat has been located, the swimmer may proceed beyond the 1500m marker.

Support boat starts
The support boat should act in accordance with its swimmer’s wave start time and the boat coordinator’s instructions:

• 30 min to start: Support boat to be waiting in one of the two holding areas
• 15 min to start: Boat to proceed to the front of the holding area
• Via VHF Channel 71: The boat coordinator will advise when to move the support boat from the holding area to the start channel; be sure to avoid mixing with previous start wave support boats leaving the start channel
• Meeting your swimmer: Support boats must meet their swimmer after the swimmer passes the 1000m green-coloured buoys; boats must not approach their swimmer within 1000 metres of shore

Race officials patrol the holding areas and start channel to ensure that support boats maintain proper positioning.

No changeovers at the start
No duo or team swimmer changeovers may take place in the first 1000m of the event for safety reasons. If a swimmer is in distress and requires assistance before the 1000m buoys Fremantle Surf Life Saving will assist and the swimmer’s support boat will be informed via radio.

During changeovers, skippers of boats with single engines must put their boat into neutral and only engage them when instructed by the spotter. Skippers of boats with double outboards must turn the engine completely off before taking the swimmer on board.

Boats should not circle towards other swimmers’ paths during pickups.

Boats should not go astern at all; however, skippers can use reverse thrust to stop the forward way of their boat to avoid swimmer, paddler, or vessel collision. This must be done in a controlled manner with the skipper checking that it is all clear directly behind the boat before acting.

Extreme caution should be used when picking up swimmers and paddlers. Solo swimmers have right of way and interference should be avoided at all costs.

Spotters provide assistance as needed to ensure safe changeovers, including the safety of other swimmers and support craft.

Support Boats at 18km & 19km markers

The swim course can become heavily congested between 18km and 19km. For this reason, support boats may be asked by event officials to leave their swimmer/s at the 18km buoy. Support boats that proceed past 18km are encouraged to navigate to the boundaries of the swim course until 19km at which time they must exit the course.

At the 19km marker, support boats still on the course must leave their swimmer/s and depart the swim channel by veering to the north or south. Boats must not cross back over the swim channel; if they do so, they risk disqualification of their swimmer/s.

Once their swimmer/s has completed the event, the support boat can choose to moor or return to the mainland.

General traffic
This includes general announcements and safety warnings (e.g., navigation guidance, alerts to shipping movements in the channel), responses to radio checks, and other non-urgent communications from Port to Pub Swim Base (PPSB) via VHF Channel 71.

Mayday call
The distress call Mayday may be used only if the boat is threatened by grave and imminent danger – for example, sinking or on fire – and immediate assistance is required. This distress call has absolute priority over all other transmissions and may be transmitted only on the authority of the skipper or the person responsible for the safety of the vessel. Stay calm, explain the problem, and give position and distress information clearly:

“Mayday, Mayday, Mayday. This is… [vessel competitor number]. Our position is… [Details of the vessel’s position]. Our vessel is… [Nature of distress and assistance required is identified]. I have… [other information including number of persons on board].”

Mayday calls are made via VHF Channel 16.

Pan Pan call
The urgency call should be used when the distress call cannot be justified but there is an urgent message to transmit concerning the safety of the vessel or the safety of a person (for example, mechanical breakdown, medical emergency, or a man overboard).

“Pan Pan, Pan Pan, Pan Pan. This is… [vessel competitor number] requiring urgent [medical or vessel] assistance. “Our position is… [Details of the vessel’s position]. I require… [Details of assistance required and other information].

Pan Pan calls are made via VHF Channel 16.

We recommend that skippers plan for and plot their course ahead of race day. Course information can be reviewed in full on the Course Information page.

Look at local weather sites to make informed decisions on the course you will take; recommended websites include seabreeze.com.au, windy.com, willyweather.com.au, and coastaloceanography.org (which also provides valuable information about currents).

Skipper tips ahead of race day:

• Enter the marked coordinates provided above into your GPS/plotter.
• Confirm which side of start boundary (North or South) you will meet your swimmer. Have a back-up plan for what to do if you don’t immediately find your swimmer.
• Skippers without plotters can download the Navionics/Aus/NZ and/or Pro Charts Marine Navigation apps to help with navigation.

Skipper tips for race day:

• Once called into position by the Race Director, the skipper should go to the approximate area to meet their swimmer. When in this position, set “go to” on plotter to build track to first km buoy marker.
• As you reach each marker, set another “go to” to the next buoy. If your swimmer or boat drifts off the set route, simply reset another “go to” and start another track. Zig zagging to get back onto rhumb line is not suggested.
• Take note of how your boat drifts when you stop for feeds or other reasons (zoom in on plotter to do this); this will provide information on current and wind influence and help make decisions about your route.
• Once at the 17km and 18km markers make sure you are on the rhumb line or within close proximity.
