A 77-year-old solo British yachtsman is feared to have drowned off New Zealand after his boat was found submerged near rocks on an isolated area off Cape Reinga, in the far north of the North Island, police said Friday, according to dpa. Divers searched the 7.6-metre Boadicea but did not find the body of Malcolm Widdilove, a resident of Britain who reportedly sailed regularly in New Zealand waters. His sunken boat was found on Wednesday.
