They're a type of wakeboard binding system, similar to snowboard bindings where boots that stay on your feet straps into a 'chassis'.
Would everyone do Cardiff and it's wakeboarding and kiteboarding residents a huge favour and sign a petition to get the planning decision approved for a wakeboard cable park in Cardiff Bay. At the moment they aren't going to approve on the grounds that there is not enough demand for a cable park in comparison to the disruption the building work might cause but with enough support we might be able to change this! Petition takes literally 30 seconds to sign!
Petition Cardiff Warf Wakeboarding Park Support
Thanks!
