Overview
NEMO compresses everything U-Boat Worx has learned about deep-sea engineering into a single-passenger craft small enough to launch from a tender, a dock, or the swim platform of almost any yacht.
A fully acrylic pressure hull wraps the cabin in glass, putting pilot and passenger inside an uninterrupted 360° view of the reef, wreck, or open blue beyond.
Designed for series production rather than one-off builds, NEMO brings the cost and lead time of private submarine ownership down to levels never seen before in the industry.
