Hi Sweetrevenge, Thanks for your interest - unfortunately I had a problem the following day - I tried the sub in the test tank and found that I still had an air leak - after a couple of tries with various combinations of rubber bands I eventually managed to strip the thread at the front of the tray. I went to our local hardware shop and bought some larger size bolts and wingnuts. I've replaced the thin threaded bolt now and started glueing things back together. I remember reading on one of the forums some time ago that someone with a Seawolf had done the same - it just means that I'll have to take the top nose cone off after a days sailing to get the battery out - but that's not too long a job. I've since been told by some folk on one of the other forums that they seal the rear gasket with Vaseline or similar to keep the thing watertight, so probably tomorrow I'll be trying the test tank again. In the meantime here's a piccy from yesterday.
