One of the biggest problems is the proliferation of lines. Let's put a shotline on every underwater feature because we can't be arsed navigating. It's been ten years since I did my first dive there and the layout looks nothing like it did then. I've lost count of the number of dives I've done at Dorry but I still got lost because of the sheer number of ascent lines.

When I first dived there the lines were simple. Main buoys to the plateau, the buoys to the deep section, one on the pinnacles and maybe a couple of others in the shallow bits. They were also decent marine-type buoys as well. Last year you could walk from one side to the other on stuff floating there, shitty plastic kegs with crap line. The last time I used the deco bars they weren't even at the right depth.

I've pulled a lot of navigation lines out of there too (not shot lines). Typically crap laid lines i.e. drag a reel through the water to where you are going, no belays, no tie offs, nothing, so it just forms nice, big floating loops after a while. I haven't been in the 57m tunnel for a while but the last time I was the line was floating mid water in it. Sorry if it offends anyone, but if you can't navigate your way round a quarry then maybe diving isn't the sport for you.

The state of the area around the main car park is terrible as well. Piles of used lime in the buildings, batteries, disposable barbeques and other rubbish chucked in the water.
