Welcome to Tresaith Mariners Sailing Club, a coastal catamaran and dinghy sailing club in West Wales.

We run weekly training nights as well as Sunday racing and several summer regattas and beach parties. The F18 catamaran fleet and 29er Youth fleet also regularly attend national and international events. See the links in the menu above for more details.

We are very grateful to In the Welsh Wind for sponsoring our club this year. They are a local craft distillery making premium gin and other spirits.

Defibrillator campaign
Members of the Tresaith Mariners Sailing Club have been successful in raising funds for a defibrillator to make the club, the beach and all its visitors heart safe. Having the defibrillator installed on the outside of our building means that, through its link to the Local Ambulance Service, it is available to everyone at the Club and the local community 24/7.

The defibrillator was installed in June 2018

Training Night Fees

Training & safety boat cover fees (Wednesday nights) are £10 per session for non-members and £3 per session for paid-up members (free for members in 2021). This includes use of club boats or your own boat, safety cover from our RIB and coaching if required/requested. The money goes towards safety boat fuel and maintenance, and maintenance of club boats. All coaches and instructors are volunteers, and so you are asked to help rig boats and pack all borrowed kit away.
