The Fleet is divided into three areas with different restrictions on boat activity.
- All forms of boating are banned in the West Fleet beyond the Langton parish boundary.
- In the mid Fleet from the Portland boundary stone at The Narrows up to the Langton parish boundary rowing boats and canoes can be used. The use of motor boats and sailing craft is actively discouraged.
- From the Narrows down to Ferrybridge the use of rowing boats, canoes and motorboats is permitted. The use of sailing craft is discouraged because of the restricted water making it difficult to safely control such craft. Please note there is a speed limit of 4 knots in the lower Fleet.
- Boats beached on Chesil Beach are usually associated with permitted fishing activities. Similarly, boats on the Fleet landshore have traditionally been involved in fishing activities. Permission should be sought from the appropriate landowner before leaving a craft on either shoreline. All users of pole moorings should register with the Fleet Warden.
The fishing for salt-water fish from Chesil Beach does not currently require a licence. Fishing is only permitted in the Fleet from the Narrows down to Ferrybridge and even then it is only permitted from the shore and by rod and line only. Fishing from boats is not allowed in any part of the Fleet.
The only permitted freshwater fishing activity is for eels using special fixed nets in the mid-Fleet. This activity is carried out under a licence from the Environment Agency and a permit issued by the Fleet Warden.
Off-road vehicles and mountain bikes
There is no bridleway access along any part of Chesil Beach or any part of the Chesil Beach and Fleet Nature Reserve. The use of any type of off-road vehicle and the riding of bikes is not permitted on any part of Chesil Beach or around the Visitors Centre at Ferrybridge or on Hamm Beach other than on the designated car parks.
