 In his quest to personalise submarines for everyday use, Bert teamed up with a Canadian inventor, Peter Mitton, who had pioneered a small one person Sub (C - Quester) that provided the template for what was to follow.That partnership ended in 2005; Bert Houtman founded U-Boat Worx determined to expand the audience for private submersibles.A production line approach has seen a wide range of models with ever increasing capabilities reaching greater depths, continuously adopting the latest technology, craftsmanship, and delivering more fully certified vessels for a variety of end users than any other manufacturer.
