BY ROAD
Thornham Marina is located near Emsworth, approximately five minutes by car from the A27 trunk road between Chichester and Portsmouth. Whether approaching from east or west, leave the A27 at the A259 Emsworth exit and follow the Emsworth signs. After approximately one mile (passing two petrol stations on your left), you will come to a roundabout. Go straight across this and follow the road over the mill pond causeway and up a small hill. Approximately 500 yards further on, immediately after the Emsworth Wine Warehouse, turn right into Thorney Road. Continue for about half a mile and then turn left into Thornham Lane (you will see a sign for Thornham Marina). The Marina is about half a mile along Thornham Lane on your left.

BY SEA
Enter into Thorney Channel and proceed north, past Thorney Island Sailing Club and Church on your left. Follow the moorings all the way up to the entrance to Prinsted Bay. After entering Prinsted Bay, you will see the boats on the pontoon moorings ahead to the left.
