Portsmouth Sailing Club are the hosting the Worlds, the club  was founded in 1920 and local artist W. L. Wyllie, famed for his maritime paintings and etchings was amongst the founding members. The clubhouse, a Grade 2 listed building, was probably constructed in the early 1800s and many of the timber beams visible inside are from ships broken up at that time. Previously serving as a Consulate to thirteen different nations and somewhat less illustriously as a French onion store this wonderful building now lies at the heart of a vibrant and active club membership. The club is managed by its members for the members; this creates a friendly atmosphere and strong community spirit that supports a varied social programme and extremely accessible range of activities on the water.

Hornet Services Sailing Club is the home club to most of the Tempest on the south coast and will where the tempest will be moored for Worlds. The club was formed in 1964 as Naval Yacht Club be formed for serving and retired naval personnel. In April 2013, in recognition of the increasing part the Club was now playing in support of service off-shore sailing, a decisive vote was made by members at the AGM, to amend the name of the club to Hornet Services Sailing Club (HSSC). This reflected amendments to the Club’s Constitution that opened up membership to personnel from all three of the Armed Forces, their veterans and families.
