This video was recorded in Mandurah, Western Australia on a famous run, 'the fremantle doctor'.
The Zephyr in action.
The increased vertical bow volume as well as the flattened deck towards the stern handle the
conditions very nicely - no pearling and no green water.

During summer months it consistently blows from the South-West along the southern half of the west coast, starting between noon and 3 pm. It can penetrate as far inland as 100km, reaching York in the early evening.
In Perth, the capital city of Western Australia, the wind is named the Fremantle Doctor because it appears to come from the nearby coastal city of Fremantle, and it brings welcome relief from the summertime high temperatures. However, it is almost certain that the term Fremantle Doctor has its origins in Fremantle's dark past. At Catherine Point, a short distance south of Fremantle, crematoriums were established during the colony's early days to dispose of the corpses of those who had fallen to the illnesses which preyed upon the population in the city's early days. It is reported that the Doctor was named in honour of the wind which blew the stench of burning human flesh inland, as this was otherwise noticeable in both Fremantle and her environs.[citation needed]
The Fremantle Doctor often cools the Perth suburbs by several degrees, whilst nearer the coast the wind can be quite strong, often blowing between 15 and 20 knots and making afternoon beach visits unpleasant.
On days when the wind fails, the afternoon temperatures of Perth suburbs are considerably higher, often reaching 40°C, although this is also attributable to the influence of a strong easterly wind blowing in hot desert air from the arid interior of the state.( source Wikipedia )
