The Court of Arbitration for Sport has reduced sailor Dirk de Ridder's suspension from three years to 18 months after his rule violation prior to the 2013 America's Cup.

De Ridder was suspended by the International Sailing Federation for his alleged involvement in the manipulation of the weight distribution of boats sailed by Oracle Team USA in warmup regattas.

De Ridder appealed to CAS, seeking to overturn the suspension.

The CAS panel, though reducing the ban, found that de Ridder gave instructions, express or implied, to add weight to a boat.
