USS Lamson

Diving the USS Lamson

This wreck is great as its not too big so you can really take your time and see all of the wreck.The viz was crystal clear and we spent most of the dive on the outside of the wreck - which is normally unheard of! But there was just so much to look at.

Sitting bolt upright, again, sand at about 55m (180 foot) with deck averaging at about 48-49m (157- 160 foot)


USS Lamson, a 1500 ton 104m long Mahan Class destroyer, was first launched on the 17th June 1936.
