Dateline Saturday 19 May 2012: Today, Bogglehole Bill uploaded a BogCast showing the kind of obstacle that can be encountered when bottle diving - a sailing boat moored to a sinker by means of an anchor chain.

"This is the sort of thing that you can quite literally bump into", explained Bill. "Even if moored boats are obvious at the surface, it can be difficult to correlate their locations once underwater. The best way to avoid this type of obstacle is to mark its location by survey".
