Reichel/Pugh had generally adopted the Serendipity 43 parameters for their new design but gave Sidewinder slightly more sail area, as well as a considerably greater righting moment (RM), by 11%. The increase in RM was due to a number of factors - she initially had 800lbs less internal ballast than Scarlett O'Hara, much of which was in her keel instead; her up-to-date hull and deck construction, including two full-length longitudinals, which saved weight up high; and had 3.5 inches less freeboard than Scarlett, which lowered the weight of the deck and hardware. Sidewinder initially rated 33.6ft, slightly more than Scarlett's 33.2ft, but this was brought down for the 1985 US Admiral's Cup trials to 33.0ft.

A second boat to the Reichel-Pugh design was launched for owner Roger Livingston, being the silver hulled Lobo. This later boat is thought to have been constructed in a more advanced layup, and carried a slightly lower rating than Sidewinder, at 32.8ft. Livingston attracted a star line up for his boat, with Dennis Connor on the helm and Tom Whidden as tactician.

Denmark, France, New Zealand and Papua New Guinea joined the British in selecting an all One Tonner line up for the 1985 Admiral's Cup. Indeed, 34 of the 57 boats in the fleet were rated at or near the 30.0ft minimum. Against that trend, the US team was comprised of three boats rating near the maximum limit set by the selectors. It did not prove to be a winning combination.

While High Roler had a fantastic second race, winning by two minutes on corrected time, Sleeper and Sidewinder came unstuck after leading early on the Island shore when the breeze faded as they tried to come back to the mainland. The Channel Race was a small boat benefit with plenty of fresh air reaching. On the leg to France, Sidewinder watched a One Tonner hitch a lift on her quarter wave for a free tow, but then break off to sail on her own - faster. Sidewinder, rating a full 2.5ft higher, promptly latched onto the quarter wave of the smaller, faster boat.
