Hello; Submarines and underwater vessels aren’t generally found in the listing of personal collectible items. However there are certain noteworthy exceptions to this trait. Exceptions that have not only re-defined the boundaries of submersible vessels, but have also reshaped the potential experiences of a sub-aquatic tour that people can enjoy. Personal submarines as they are famously known have enabled people to explore the depths of the marine world. Quite a few of these submersible vessels are privately owned by well-known socialites and marine sports enthusiasts. However some engineering companies have come up with awe-inspiring submarine models that can be acquired by interested people, even other than such high profile individuals. There is a big difference between the rest of these vessels and this proposed "Phoenix 1000". The others (many of which already exist and are in service) and the Phoenix 1000 (which does not) is that they are basically water toys. The concept of a true "yacht" style submarine has been around for decades but has not been produced. It would most likely be restricted by maritime laws pretty much everywhere. True submarines are potentially hazardous even with highly trained crews. Something like this over 200 feet long? What would it use for power? Yeah, submerged it can use batteries but how long could they last without recharging? They have to provide propulsion and life support as well as all electrical equipment required for safe operation. Will it have a diesel engine like military submarines? They require a lot of resupply and maintenance and if something goes wrong, as often does even on surface vessels, God help you. Try to get insurance for something like that.
