Notice: 03 – 21 General Information – Prada Cup Friday 15 January to Monday 22 February 2021

For details on how to watch the Prada Cup races, please go to the America's Cup watch on the water website. Sign up on this website to receive the latest information.

The Waitematā Harbour and approaches to the courses will be significantly busier than normal. Please navigate with caution at all times.

Due to the anticipated large number of spectator vessels, 5 knot speed limits will be in force on race days. Details are on the America's Cup watch on the water website.

All mariners should be mindful of the wake that their vessel generates and should keep their wake to a minimum by not exceeding the speed limits.

Mariners should also familiarise themselves with the dangers associated with the wake of large concentrations of vessels. They should ensure that their vessel is suitable to navigate in confused seas caused by wake. For their own safety skippers of small vessels are dissuaded from attending the event, however if they determine it is safe to do so they should ensure that lifejackets are worn by those onboard whilst navigating in congested waters.

Unpowered vessels are discouraged from attending the event due to the possibility of being affected by wake and due to them potentially being less manoeuvrable amongst concentrations of other vessels.

Buoyed transit lanes have been established adjacent to some of the courses to allow vessels to navigate around the course perimeter. These transit lanes have been surveyed to provide a depth of 2.5m at Chart Datum. As with all buoys, they should be used as an aid to navigation and Skippers should verify their position by alternate means.

Within the transit lanes, which are activated dependent on the race course being used, vessels must be capable of navigating at 5 knots, must be power driven, must have no sails hoisted and may not turn around or stop within the lane.

Spectator vessels will be managed by a fleet of Course Marshal boats. These boats will be branded as such and the crews will be warranted Enforcement Officers. Please follow instructions
given by the Course Marshalls, they are volunteering their time to keep you safe.

Spectator vessels should maintain a listening watch on VHF ch.16 and ch.04 for instructions from the Chief Marshall.

The racing yachts, team chase boats and some vital event support boats have exemptions to exceed the speed limit provided that certain conditions are met. Please do not attempt to follow or keep up with these vessels.

At the conclusion of the races, it is likely all spectators will disperse at the same time. This has the potential to generate a confused sea. Smaller vessels and vessels prone to be affected by wake are advised to wait until boat traffic subsides before navigating home.

Course A is within the Cable Protection Zone. Anchoring within the zone is prohibited. If you do anchor, course Marshalls may require you to sacrifice your anchor for later retrieval so as to
prevent damage to the cable.

Movement of vessels 40m LOA or more is restricted on race days. Masters of these vessels should contact the Harbourmaster for further information.

The whole success of the event is reliant on mariners being responsible and following the rules. Please do the right thing and help make this regatta a hugely successful, safe event.

More information is available on the America's Cup watch on the water website, and the AT HarbourMaster America's Cup information for skippers website.

Thank you.

Normal Collision Prevention rules apply to all vessels and the race vessels have no special privileges.

These race vessels may be navigating at far higher speeds than those normally encountered and situations between vessels can develop very quickly. All mariners should maintain a particularly vigilant lookout when in these areas.

Whilst navigating in the Waitemata Harbour Restricted Area en-route directly to and from the training areas, the race vessels may either be escorted under sail, or be towed, by up to two syndicate branded power driven support vessels. The support vessels will exhibit orange flashing lights and will have working AIS. They should also broadcast an “all stations” call on VHF Ch.12 prior to transit. The race vessels may be navigating at up to 25kts in this area.
