Vessels wishing to enter or leave the port should contact Port Control to obtain information and get updated information on works. Vessels should only pass the work site/piers once permission has been granted. Small vessels should be able to pass through the piers during the works, however, should afford as wide a berth as is safe and practical, and pass at slow speed to reduce vessel wash. For large vessel movements, port control will liaise with the contractor to arrange a suitable time for the work vessels to clear the worksite to allow safe vessel transit. Timings for the works will be subject to suitable weather and tidal conditions. For further information please contact Lowestoft Port Control, (VHF Ch.14, Tel. 01502 572286).
