• Website:

• Handbook:
A handbook is produced each year, containing contact numbers for all officers of the Association and all members, the latest Class rules and any articles about the boats and the Class.

• Newsletter:
A newsletter is regularly sent to all members.

• Racing:
There are fleets of Sigma 33s which regularly meet to race in the Solent, the Clyde, Ireland (both Belfast and Dublin) and the West Country. Racing in most of these fleets is excitingly close. The boat is equally suited for inshore “round the cans” racing and for offshore races – a Sigma 33 won its class in the 1999 Fastnet Race. Contact the Class Secretary for programme details.

• Nationals
The Class Championships/Nationals are held annually at a different
location each year – Bangor 2016, Cowes 2015, Abersoch 2014, Helensburgh 2013, Dublin Bay (2012), Bangor (2011), Cowes (2010), Tarbert (2009), Dublin Bay (2008), Yarmouth, Isle of Wight (2007), Belfast (2006), Torquay (2005), Cork (2004), Dublin Bay (2003), Clyde (2002), Falmouth (2001), Cork (2000).


• Boat tuning
Class measurement rules are strictly enforced for racing, so all boats carry effectively the same equipment, which makes for close and exciting racing. Tuning the rig is more art than science, however the stalwarts of the class are always ready to provide guidance. Call the Class Secretary for an introduction.

• Crew Training
Training days for new owners or for new crew are held in the Solent each Spring, at which experienced skippers and crew help to show how to do it all. A list of people wanting to crew on Sigma 33s is kept on the website.

• Ratings
In order to race in Class events, all Sigma 33s must have a valid rating certificate stating that it is rated to Class Rule limits. Certificates are issued annually by the RORC Rating Office in Lymington (tel.01590-677030). Under IRC the 2011 TCF is 0.914.

• Radio Licences
International Radio Regulations require that every vessel with a transmitter should have (a) a Ship Radio licence and (b) be operated by a person holding a certificate of competency. Licences are issued by the OFCOM Licensing Centre, PO Box 56373, London SE1 9SZ (020 7981 3000).

• Brokerage
The Association is keen to put potential boat buyers in touch with owners who are thinking of selling their boats. Contact the Class Secretary for details, and/or view link below.
