Ideal explorer yacht submarine
We’ve been looking for a yacht sub for some time and recently ran into the VAS submarine models from GSE Subs srl in Italy, a mostly military contractor with a 30-year pedigree of building submarines. In the US they are represented by Nautilus Underwater Systems. The people at Uboatworx in the Netherlands also upgraded their design recently. Add the line of personal subs from SeaMagine in California and you now have some real choices when looking for a certified personal submarine from companies that have gone well beyond nice 3D models or unstable models with very minimum freeboard.
So I decided to dedicate a post to comparing these 3 models. Of course, there are also the SeaMagine submarines which I have covered in an earlier post.
The most affordable entry in this field is C-Quester 3. At about Euro 550 K you get a 3-seat sub that is certified by Germanischer Lloyd. The Quester 3 can also be configured to take the pilot and 3 passengers but while making this attractive in commercial use, I doubt it will be very comfortable.
There’s also a 340 kg payload limitation so ideally this 3rd passenger is a kid and the airconditioning needs to work. With its new lithium batteries it now has a very practical 6 hours of autonomy and 96 hours of life support.
With a maximum operational depth of 100 m. (300 ft.) you can cover any area where you typically would like to make recreational dives.
Weighing only 4.500 kg and relatively small, this is the only personal sub you can put on a big yacht as an afterthought. You may need a bigger crane but not much more.
The main drawback of the Quester models is its limited downward view forward due to the seat location. It won’t be a major issue for general sightseeing when you’re between a shoal of sharks or passing by a coral reef wall as you can see on the picture in an earlier post. But for but more serious work, including picking up things you’ll have a problem. But then again, you save almost $ 1.5 -2 million depending on the configuration compared to the next in line, the SeaMagine Triumph.
