On another occasion, a jet ski attempted to swamp a dinghy carrying a child by doing “doughnuts” around the boat, filling the vessel with water in an estuary with fast, powerful currents. The incidents were described by Conwy’s Harbour Master Matthew Forbes at a Harbour Committee meeting at the council’s Coed Pella headquarters yesterday (Wednesday) evening. “We’ve had a really fraught summer with jet skis this year in the (Conwy) harbour. We’ve had a number of complaints from people in Deganwy and people out on the river,” Mr Forbes told the committee. “But at the weekend we had a jet ski going 35 knots through the middle of the harbour,” he said.
