Passage north through Portchester Lake

At night make for pile 57 and look for pile 95 until the channel opens. Both these piles are visible at 3.2 miles. Two unlit spherical yellow buoys mark foul ground to the north of pile 94, leave these to starboard. The best water is defined by large unlit buoys, which should be left to port - the channel here is defined by lit starboard piles 93, 92, 90, 88 and 86. 

Pass pile 63 to port and 88 to starboard, the channel narrows and bends left. North of pile 86, the best water is close to port piles 66, 67, 68. Take care not to confuse piles 82 and 85 marking the entrance to Tipner Lake with the main Portchester channel. Lit piles 68 and 80 mark the sharp turn left into the final section of the channel with Portchester Castle to port.

This section is marked by moored yachts. From pile 80 turn slowly almost due north to pile 79, avoiding shallow water north of pile 80. At pile 78 call Port Solent on VHF channel 80 to request a lock in. At low tide keep to the port side of the channel to pile 72A, then take the starboard side. Pile 75 opens the channel between rows of piled yacht moorings.
