During WWII the U.S. 7th Fleet was based in Havannah Harbour.....(or Harbor for Americans!)

U.S. armed forces stretched submarine nets across both entrances then at the end of the war, dumped them. One has been dropped in situ between Lelepa and Moso island but offers little stimulation because it is shallow and over dead terrain. The other, however, was pulled to the side, the steel buoys punctured and the whole mass dropped in 30m, along with bits and pieces of planes and other war relics.

The result is that over the years it has formed into a wonderful natural reef with built in 'apartment rooms' for a surprising variety of coral fish, from thumb sized to adult, decorating the montage of coral covered cables like gaudy brooches.

Stripy perches flow in and around the nets in an uninterrupted wave while bright blue trigger fish with tails like kites swim from bommie to bommie like Darth Vader's tie fighters. Divers are led to the bommies and nets by black sands winding like a well manicured garden path. It is one of those surprising and totally unexpected dive sites, very easy for the novice, enthralling for the experienced..and known only to us.
