LONDON (Reuters) - Designing, building and eventually sailing the new breed of America's Cup boats will pose "one hell of a challenge", Land Rover BAR's new CEO Grant Simmer said on Tuesday.

Simmer was reacting to the radical concept design of a 75-foot foiling monohull to replace catamarans revealed by holders Emirates Team New Zealand for the 36th America's Cup in 2021.
