U-Boat Worx

U-Boat Worx is a Dutch private submersible manufacturer based in Breda, the Netherlands.

U-Boat Worx delivers crewed submersibles for private use, and has focused primarily on the superyacht, cruise ship, and leisure/tourism markets.

The company maintains that "U-Boat Worx" is derived from "underwater boat”, referring to the "boat-like handling" that was distinctive in the original designs and is not a reference to the German U-boats employed by Germany in the First and Second World Wars.

U-Boat Worx produces a range of versatile subs for all underwater activities, including the flagship model that can dive to 3,000 meters (9,845 feet).

History
Following a successful career in the software industry that culminated in the Stock Exchange listing of Houtman's company, Exact Software, Houtman sought to buy a personal submarine for his own use.

To his surprise, he discovered that submersibles were the exclusive domain of military or institutional scientific users. Houtman, sensing a market opportunity, teamed up with a Canadian inventor, Peter Mitton, who had pioneered a small one person Sub (C – Quester), which provided the template for what was to follow. The partnership with Mitton ended in 2005.

U-Boat Worx was founded by Houtman in 2005.

Custom technology
MANTA Controller – to allow for supervised passenger steering U-Boat Worx developed the MANTA Controller. The pilot can hand over the controller to an untrained guest to let them navigate, under supervision.

MARLIN Controller – To make launch and recovery of the submersible easy and safe, U-Boat Worx developed the MARLIN Controller. This controller allows for wireless control and navigation on the surface without having a person inside the submarine.

U-Boat Worx was the first submarine manufacturer who applied lithium-ion batteries in her submarines with classification by DNV GL.

Pressure-tolerant battery technology – U-Boat Worx developed a pressure-tolerant battery system with an increased capacity of 350% when compared to lead-acid batteries used in non-U-Boat Worx submersibles. The technology has been tested to 13,000 feet and stores a total of 62 kWh on compact battery modules.
