The last commissioned boat the Gougeon Brothers built was Adrenalin. Started in 1984 and launched in 1987, she is a trimaran with articulating amas built to Formula 40 rules for Bill Piper of Ossineke, Michigan, and intended to race on the European circuit. She shocked the sailboat racing community by placing a very close second in her first regatta on the Grand Prix circuit in 1988. She raced for two seasons in Europe against the traditional big cats until, as Jan Gougeon put it, “They couldn’t stand being consistently beaten and changed the rule so the boat became illegal and only cats could race.” Adrenalin was purchased by New Zealander Grant Beck in 2007.
Built from wood and epoxy, Adrenalin has articulated amas (floats) which pivot from the front beam). Photo © John Bertenshaw, used with permission.
Adrenaline is now jointly owned by Rodney Keenan and Colin Palmer/Adhesive Technologies Limited, and they have recently re-assembled her in Auckland. Apart from the articulated wave-piercing floats, she also features a rotating wing mast and boomless main.
The aft end of the floats (amas) are supported by a wood/epoxy leaf spring. Downward travel is limited by a control line (the blue one). Photo © John Bertenshaw, used with permission.

The following short video shows Adrenalin out sailing on Auckland harbour. You can plainly see the windward float (ama) pivoting freely out of the water, as well as the leeward float pivoting relative to the centre hull. You can also see how fast she is in this light breeze.
