We have both built and restored dive boats a number of times over the last 27 years. First there was the 50 foot Nautilus VI which we converted from a yacht. Then the 85 foot Nautilus VII, an old wooden WW2 sub chaser that had seen much better days but was all that we could afford! Following that, the Nautilus Explorer was our first brand new build and she is beautiful. The 102 year-old Nautilus Swell followed and while she was originally launched the same year as the Titanic (1912), the ship was in immaculate condition and well-loved by all. Our big, beautiful Nautilus Belle Amie was our next new build, followed by a massive renovation and stretching of the Undersea Hunter of Cocos Island fame.
