both the Wye and the Lugg, but established the Environment Agency as the navigation authority for the rivers. It also banned the construction of locks and weirs, so neither river is likely to be navigable by motor boats under normal circumstances. Despite this, in 1989, Frank Barton and Pat Hucket successfully navigated a 230-ton barge up the river to Hereford. Travelling time on the river was 20 hours, but this was spread over six months, as they had to wait for just the right water levels. The vessel was renamed Wye Invader during the journey. In March 2019, Barton returned to the river, navigating a narrowboat called Wye Invader Two from Sharpness to Monmouth Rowing Club and back again. The trip was possible because there was about of flood water in the river, enabling the boat to pass over the weirs and obstructions. Navigation and sport The Environment Agency is the navigation authority for the river. The normal tidal limit (NTL) of the river is Bigsweir and navigation below this point is under the control of the Gloucester Harbour Trustees as Competent Harbour Authority. There is a public right of navigation up to Hay-on-Wye, and canoes are generally permitted on the next up to Glasbury, so long as they do not disturb anglers. The River Wye provides for canoeing and kayaking as it has sections suitable for all ranges of skills and free access all the way downstream from Hay to Hereford and Monmouth, and the tidal Wye to Chepstow and the Severn Estuary. There are a wide range of canoe hire and supervised trips, as well as campsites at key points on the river. Symonds Yat has a particularly popular series of rapids that was purchased by the British Canoe Union in 2003 to preserve the rapids for recreational use, canoe trips through the rapids stop next at Monmouth. There are three rowing clubs on the river at Hereford, Ross-on-Wye and Monmouth. Annual regattas are held at Ross-on-Wye and Monmouth for rowers and scullers of all abilities, next to the local rowing club. In 2017 more than 600 people took to the River Wye in inflatables ranging from dinghies to paddling pools during the event WYE FLOAT, opened by former Olympic ski jumper Eddie the Eagle. Walkers can take the Wye Valley Walk which follows the route of the River Wye from Coed Hafren, near Plynlimon, to Chepstow along
