Tamar river deep channel Neal Point to Weir Point  20.03.2011


The way points below were made along a transit line defined by  aligning the Warren Point starboard hand buoy  with  the conspicuous yellow derricks at Ernesettle ammunition pontoon which is just upstream of the Tamar bridges on the Devon side.  


The Warren Point Buoy is the second green can going downstream - just off this chartlet. The transit line is a good fit with the charted channel.


Close after  low water on this spring tide the channel was sounded at all these way points and found to be more than 2.3 metres deep. (My stick was only 2.5m) This was at between 1 hour and  1 hour 15 mins  after LW Devonport at 1221 GMT  height 0.1 m , the lowest tide of the year.

WP 7  N  50  26’ 01 W  04  11’ 88  WP 8 N  50  26’ 08 W  04  11’ 87

WP 9 N  50  26’ 15 W  04  11’ 86  WP10 N  50  26’ 23 W  04  11’ 86


This transit is the one I have followed  for many years to negotiate the channel over the mussel beds without difficulty .  The way points may prove useful in poor visibility, especially if a strong cross tide is running which could set you onto the mud.

 Simon Martin has kindly forwarded the photograph on the left and that below.


Ted Coryton, the pilot of the aircraft, took them at Simon’s request during the equinoctial spring tides of 2011.


They show the shallow patches below Cargreen, and they shouldn’t have changed that much in four years since then.


Simon has pointed out that you can just make out why you need to keep a straight line from the mark on the west bank right down to the green buoys, and then take a right turn, all without straying too far east.


(With thanks to Ted Coryton and Simon Martin)

The above photographs nicely complement Mick Johnson’s pilotage information below.
