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

The club is now open and running sailing again as normal. All sailors are encouraged to book in on our TMSC Facebook Group so we know how many  people to expect and can keep you up to date with any last minute changed due to weather conditions or volunteer availability.

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 and 29er Youth fleet also regularly attend national and international events. See the links in the menu above for more details.

Tresaith Mariners Regatta & Beach Party – sponsored by In the Welsh Wind

The date for the regatta is Saturday 14th and Sunday 15th August 2021. Beach bar in the marquee on the beach, along with live music till late and great food. All dinghies and catamarans welcome – there will also be races for our beginners and junior sailors.

Live Band Soul Skunks

We are very grateful to In the Welsh Wind for sponsoring our event this year. They are a local craft distillery making premium gin and other spirits.In the Welsh Wind Distillery logoAn image of a bottle of In The Welsh Wind gin in front of a fishing boat on the beach.

Beach parties

We also have additional beach parties on the weekends of the 21st August and the 28th August – making up for lost time after being unable to do our events last year!

Hoochie Coochie Blues Band is playing on Saturday the 21st August, and Adrenaline on Saturday 28th August (Bank Holiday weekend).

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

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.
