Britain has been trying without success for the better part of 168 years to win back the silver trophy it lost to the schooner America in 1851 in a race around the Isle of Wight, not far from INEOS Team UK's base. Ainslie represents Britain's best chance yet. The most-decorated sailor in Olympic history with four gold medals and one silver, Ainslie helped Oracle Team USA successfully defend the America's Cup in 2013.
Ratcliffe named his AC75 in homage to one of Britain's most famous racing yachts, Britannia, which was built in 1893. Its name was in turn taken from James Thomson's poem Rule Britannia! written in 1740. That poem, of course, contains the line, "Rule, Britannia, rule the waves".
It just hasn't ruled the waves in the America's Cup, the oldest trophy in international sports.
INEOS Team UK, which is backed by the Royal Yacht Squadron, will test Britannia on the Solent before heading to Sardinia for testing. The first competition in the AC75s will be in the America's Cup World Series regatta in Cagliari in late April. INEOS Team UK plans to launch a second boat in late 2020.
The AC75 is "unlike anything ever seen on the water before," INEOS Team UK chief designer Nick Holroyd said. "It's hugely ambitious and it sets out an entirely new type of boat, and with only 18 months to design and build, there comes challenges, but that's what makes the Cup so exciting."
The broad, low-slung AC75 boats replace the foiling catamarans used in the last two editions of the America's Cup. They will be capable of speeds of up to 50 knots.
The AC75 blends the tradition of a monohull with the modern advancement of foiling, which is all the rage in sailing.
The AC75 will use twin canting T-foils to help lift the hull out of the water to increase speed. In the normal sailing mode, the AC75 will skim above the waves on the leeward foil and rudder, with the windward foil raised out of the water to reduce drag. Both foils can be lowered in pre-starts and through other manoeuvres to provide extra lift and roll control, which also will be useful in rougher sea conditions.
