  1. Sometime ago there was a thread about the amount of water used by boats of different sizes/weights when travelling through locks. As usual there were several different ideas.

     

    The answer is in this article copied from "Bradshaw's Canals and Navigable Rivers."

     

    Mr G R Jebb in a paper on the "Maintenance of Canals" read before the Society of Arts Conference on Canals, 1888, gives the following information on a point connected with the consumption of lockage water.

    "A boat locking down from the higher to lower level requires a lock full of water minus the amount it displaces; a boat locking up from a lower level to a higher level requires a lock full of water plus the amount it displaces; thus it will be seen that a loaded boat requires more than an empty one when locking uphill, and that an empty one requires more water than a loaded one when locking down hill."

     

     

    A boat locking down from the higher to lower level requires a lock full of water minus the amount it displaces.

    A boat locking up from a lower level to a higher level requires a lock full of water plus the amount it displaces.

    An empty boat requires more water than a loaded one when locking down hill.

    A loaded boat requires less water than an empty one when locking up hill.

  2. VDO Hours Counter Repair

     

    If you have a VDO hours counter not displaying the hours there is a repair procedure to change the display.

     

    It is not for the faint hearted!

     

    I bought this from RS Components. Cost about £20.

    Hours Run Meter Curtis 701PR001O-1248D2060A, LCD, 6 digits , 12 → 48 V dc, 20 → 60 V ac

    • RS Stock No. 185-6107

    • Brand Curtis

    • Mfr. Part No. 701PR001O-1248D2060A

     

    The following links will help with fitting

    A superb pictorial guide by Richard Davis on how to do this

    The meter calibration for the alternator speed will not work after modification

     

    I have done this but do not ask me questions about technique.

    It seems very reliable, 3 years.

     

     

  3. The red band and light at Stourport is 9 to 12 inches lower than the red band at Lincomb Lock which is 1 mile down stream.

     

    This discrepancy can cause a situation where a boat coming up the river leaves Lincomb in the amber and arrives at Stourport in the red. But a boat wanting to leave Stourport will not if the water is in the lower part of the red, if they did leave when they get to Lincomb they would be just above green in the amber!

     

    The best advice is to speak to the lock keeper at Lincomb.

     

    This website shows the river levels along with approximations of the red/amber/green boards.

  4. CaRT's website. Can any one help? Where can I find?

     

    After the winter stoppages what are the passage times for Bingley Five Rise Locks.

    Do I have to book a passage out of Leeds on the L and L

     

    Where on CaRT's website is this information?

  5. The Inland waterways Cruising School’s web page below shows 14 Environment Agency web sites for the River Severn levels

     

    The "Level in metres" are the EA datums and do not correspond to the Canal and River Trusts' Red Amber Green boards or levels; but they do give a good representation of the trend.

     

    Check that the time (GMT)and dates are correct. The water levels are updated every 3 hours and are for guidance only.

     

    If you are interested in Stourport the 1.4m level at Bewdly is just about the bottom of the Red sector at Stourport.
