EX BRISTOL BERTH POCKET SHOAL

1. There are shoal depths in the ex “HMS Bristol” berth box located on the northern side of Fountain Lake within Portsmouth Harbour. The berth pocket indicates on the chart a minimum maintained depth (MMD) of 6.5m but along the northern edge of the pocket some depths are reduced to a least depth of 4.6m below chart datum.

2. If any mariner has a requirement to operate in this vicinity, they should use extreme caution due to reduction in MMD.
