Waterwise marine RNLI
Originally based on the Menai Straits the decision was made in 2018 to relocate the training centre to Madog Boat Yard, in Porthmadog.

In 2021 we added a fleet of new Sea Doo Sparks, GTI & GTX to our fleet along with a drive on Aqua Dock for running PWC Jet Ski Courses. We now replace this fleet annually.


The facility at Madog Boat Yard is second to none. The classroom is central heated, with views across the estuary, and there are showers for PWC courses and a kitchen for breaktime. Outside in the yard is an 8-tonne static crane, slipway, private pontoons and workshop. The estuary acts as a lake and we can run courses in almost all conditions.
