Evidence of the growing grip of business is everywhere. Names like Sea Spray and Waterwitch have given way to Innovex, Nicorette and Chernikeeff 2. Like many of the new names, Chernikeeff 2 comes from the computer business. The boat's owner, Peter Harrison, a vice president of Chelsea football club, built Chernikeeff into the largest privately-held networking and internet company in Britain, then sold it in two deals which brought him £300 million. He is putting together a British challenge for the Americas Cup, a project likely to swallow a large chunk of that fortune.
