Migaloo LST Dayboat Submarine
Austrian design studio Migaloo's LST is a 56-foot submarine tender concept that functions as both a dayboat and a submersible. Built from steel with a double hull design, it dives to 820 feet with hybrid diesel-electric propulsion reaching 23 mph on the surface and 14 mph submerged. The main lounge seats 12 guests under a retractable sun roof with a mini bar. Submerged, a large acrylic bow window opens onto a bow lounge, while side hatches allow underwater docking with the mothership. The LST is designed as a tender for Migaloo's 544-foot M5 submersible superyacht concept, for owners who refuse to surface between destinations.
