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

COVID-19 UPDATE (1st August 2020)

The club is now open and running limited sailing for members only. All sailors must book in on our TMSC Members Facebook Group so we have details for contact tracing requirements and to make sure that we stay within numbers allowed.

Unfortunately due to ongoing social distancing requirements we have made a decision as a club that we are not running any beginners’ training or taster sessions this summer. Hopefully these will resume next spring. Experienced sailors are welcome to contact us about joining.

Please see the RYA Cymru guidance for return to boating in Wales.

More detailed club guidance has been posted on our Facebook group by our designated Club Covid Officer – Fraser McMillan.

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

Tresaith Mariners Bank Holiday Open Event and Beach Party

The date for the bank holiday event is the 29th & 30th of August 2020 (fingers crossed – we are working on how to run this within the current and ever changing regulations!)  Beach bar in the marquee on the beach, along with live music Saturday from Soulskunks till late and great food. All dinghies and catamarans welcome – there will also be races for our beginners and junior sailors.

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, in time for the busy summer ahead.

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. 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.
