Essential Accessory for Mega Yacht Owners

The Personal Submarine

Commercial Submersibles, aka Personal Submarines, have come a long way from their scientific and military counterpart submarines. The latest essential accessory for the mega yacht owners, has initiated an up-and-coming new division for the already existing military and scientific submarine manufacturers but has also opened doors for the new manufacturers of subs specially built for super yachts.

Personal Submarines emerged for the never-ending quest of excitement sought after by the elite mega yacht owners. These new ‘water toys’ offer an astonishing unique way to enjoy the water and chase rare encounters with the underwater ocean life.

If you are on the hunt for finding the best personal submarine for your yacht, have a look at the following companies and a short summary of each. Although the obvious features to look out for are safety, operating depth, hours of autonomy, low maintenance and operating costs; these new toys for your yacht must also have a small footprint (be compact) and be light weight, an uncomplicated launching and recovery system, must be easy to navigate, and of course, comfort and luxury with undisturbed views.

Florida firm, Triton is purely a civil submersible manufacturer for leisure, scientific, film and archaeological exploration.
