You prepare yourself for an epic sprawl across the giant island your mom has set up for you. This includes standing perfectly still while the butler and the yacht's autopilot docks into the main dock, which fun fact, is technically the largest dock in the world, based purely on the fact that it stretches about a half mile out into sea and that a lot of other things are going on with it.
Your mom has so many yachts, she needs the entire dock to be completely full in order to hold almost all of them. That's exactly why she is very generous with who she allows to use them, because it would take forever to that person to steal each and every yacht. So instead, she offers a borrowing service, where she allows the person, usually of higher societal status, to borrow the yacht for a time, and in return, she gets funding for her researching. There are, in fact, 42,649.8 yachts in her possession. You may be wondering why that ".8" is there, and it's because one of her yachts she splits 80/20 with the butler as a sort of collateral for him to obtain upon any wrongdoings of her part.
This number has been sneakily rising ever since she bought the rights to the word yacht. Now whenever anyone wants to mention the word "yacht" in any IV or on any piece of media, such as clothing or a novelty mug, she gets a small portion of that earnings. It took her a couple long weeks of legal consulting and strongly worded lettering, but eventually, she got the rights, and now she can own so much more yachts.
The dock, additionally, has a tram network installed in it just so you can more easily access the rest of the armada.
