Guide to the Tide Tracker

Guide to tide tracker.

The following is a GUIDE only to assist with understanding the tide tracker that can be found at https://www.bristolport.co.uk/shipping/tide-tracker

Notes on below.

For OOD’s the main columns of interest are arrivals, sailings and channel movements.

If an inbound ship has a PO of 14:00 in general terms that ship will be at Portishead point 15:30-15:45, or one and a half, to one and three quarters of an hour after PO time.

For departures with tugs in general terms it will take one hour from sailing time to leaving the lock, for non tugged departures it takes around 45 minutes to leaving the lock.

Sometimes quicker, particularly near high water.

The request from VTS is that OOD’s look at the tide tracker before phoning in so as you at least have the names of the ships to hand and VTS staff aren’t wasting time spelling ships names.
