If you pick up one of the buoys seaward end, it will be one of the Roach Sailing association members. There are Visitors buoys level with the jetty and further upriver. You can take a tender to the jetty, but after half tide it starts to dry out. No access at low water. You can use the concrete slipway next to the jetty to get your tender further up by the sea wall.
Walk through the boat yard, out the gate and keep going down the dirt road/track until the end, the pub is on the left.
There is only one pub,The Plough and Sail and it serves cracking beer and home cooked proper food, a branch of the Oliver family..... it is a 15th century building and low beams etc. Nice to sit outside but no sea views... it also gets packed.
