That is the whole purpose of owning a luxury super yacht. It is a way to not only say I am important, but to show that you know how to enjoy yourself as well. These are ships that are designed to show a level of status and importance that no one will be able to take away from you and will allow you to go and see where it is you stand in the community of wealth and power before going to become a great player in the seas of money.
Use your cash to show what you can own in levels of material things by owning a super luxury yacht and being able to go to the ocean and just relax for extended periods of time on your own personal floating city.
Make sure to take the time to look at multiple types and styles of yachts before simply purchasing the first one you will see.
