The Louis Vuitton 35th
America's Cup was
held off of Southsea beach, Portsmouth, UK.
The vessels used are AC45 foiling catamarans.
They have configurable foils below the waterline so that they can raise their hulls out of the water for less drag. This enables them to reach speeds of 50mph+ in very little wind.
The final is in Bermuda in May/June 2017.
