One of the serious question marks hanging over the choice of a wingsailed multihull for the America's Cup has been the rigging process.

Those who were in Valencia 12 months ago would have been only too aware of the issues faced daily by the then BMW Oracle Racing team as they tried to keep USA-17 on a short leash between races, and without having to lower the wingsail each night.

A lot of thought and effort has gone into the prototype AC45, and the rigging and launching process.

Sail-World was on hand to document the exercise on Monday morning as a well drilled shore crew went through the process - which took just 30 minutes from the time the wingsail was pushed out of the shed to the AC45 splashing into the Viaduct Harbour.

Step 1: Wheel out the wingsail



Step 2: Fill the watertank on the base of the wingsail



Step 3: Attach the skyhook to the halyard at the top of the wingsail



Step 4: The remotely controlled skyhook starts the wingsail lift, as the shore team support the trailing edge



Step5: Wingsail nears vertical



Step 6: Wingsail now vertical AC45 is wheeled under the wingsail



Step 7: The wingsail is positioned above the mastball



Step 8: The first set of stays are positioned by winch and ruler



Step 9: The strain gauges are connected inside the Pelican case



Step 10: The waterbox is drained and removed from the wingsail



Step 11: A second set of stays is attached and positioned using a ruler and winch



Remote control is essential.



Step 12: The green lifting strops are attached around the mainbeam



Step 13: The skyhook halyard tail is tied off and the shore crew step off before the lift



Step 14: The AC45 is craned out over the water - just 30 minutes after rollout

Rio 2016 - Sailors talk of Life at the Extreme on the Atlantic Ocean
Certainly the Volvo Ocean Race catchcry of Life at the Extreme is not a phrase associated with the Sailing Olympics. The 470 crews were suffering the mixed emotions of survival of an extreme test by nature, the cold, and for some elation at their placings, after Thursday's battle for survival. In conditions that looked more out of the Volvo Ocean Race, than an Olympic sailing regatta, crews battled 20kt plus winds and Atlantic Ocean rollers that towered up to four metres.
