PORTSMOUTH, England (Reuters) - Ben Ainslie named his new multi-million-dollar America's Cup yacht "Britannia" on Friday as he launched the revolutionary foiling AC75 he hopes will bring international sport's oldest trophy back to Britain.

Ainslie's INEOS TEAM UK are aiming to challenge Emirates Team New Zealand for the America's Cup in Auckland in 2021 and the futuristic boat will soon be put through its paces on the waters of the Solent, near his base in Portsmouth, southern England.
