    Chepstow (NDAC) mapping/bearings - shallow end

    I'm sure these are on here somewhere already no doubt, but as I had to do em for my DM, I may as well post em for anyone that wants to use em.

    Kicks are approx. Numbers correspond to NDAC's own map

    Training Platform (2) -> Training Platform (4) - 50 degrees / 10 kicks
    Cruiser (3) -> Training Platform (4) - 170 degrees / 10 kicks
    Training Platform (4) -> Plane (5) - 30 degrees / 8 kicks
    Plane (5) -> Truck (8) - 100 degrees / 5 kicks
    Truck (8) -> Helicopter - 200 degrees / 14 kicks (This will take you via Training Platform (7))
    Back to road - 270 degrees (then follow road back to pontoon)

    The bearings have been dived so should be correct. I know most of these can easily be found by sight, but with vis like at the weekend, came in handy

    That could come in handy. I was at one point tempted to do something like that myself.

    Just for reference what was your distance per kick calculation to convert that to (approx) meters?

    Didn't measure it - was my kicks, hence approx

    That said, the distances are short are the objects relatively big, so just follow the bearings & keep ur eyes open & u shouldn't miss em (and will get a more accurate idea of your own kicks at the same time). In good vis, you could find em without, but at the weekend it was like 2-3m vis in shallows - sitting at one end of training platform I couldn't see someone if they were at the other end.

    On another thought, if anyone has the other bearings - chip em in, perhaps someone can use em.

    In the intermediate depth, the devon aircraft (14) is due north of the BAE plane (17) and the Wessex helicopter (12) is just slightly west of north from that - maybe 350/340 degrees. From there the other helicopter above (6) is roughly NW.

    Ive been tempted to swim to each buoy and take accurate surface bearings at once point before realising it was far too much swimming and effort.

    If i get bored there and the vis is rubbish next time i may take a reel or tape and measure some distances as well. I do need to find things to do there now !

    Problem is not everything's buoyed, and can sometimes be difficult to figure out what each buoy is if you don't already know, since the buoys don't seem to correspond to the layout on map

    I used my reel - looped round object, clipped to line and then took bearings from along the line (and then dived em next day). Draw 1m markings on your reel line & do the same thing & you'll have a fairly accurate measuring tool to do both

    Alternatively: jump in anywhere at random and fin off in any direction. You'll soon bump into something, it's packed with stuff at the shallow end.

    What we need is more stuff in the deep end.

    I've never seen any home-made tribute plaques bolted to the attractions at Alton Towers

    Yes please - the buses going in at 50m will at least help a little. A few other things a little deeper would be nice

    Last time i tried that i just kept bumping into open water classes.


    Will be nice when the buses go down though. Not that i've got any interest in buses on the surface but cover them with water and suddenly they're interesting.
