As a practical matter a boat
can be too big. Assuming you have deepwater dockage in your back yard (which is typical in parts of Florida) you want a boat that you can use with family and friends
without needing a crew. This usually means a boat under 90’.
If you don’t have a deepwater dockage in your back yard then you are paying through the nose for dock fees and taxes. You might be thinking, “if you can afford a nice boat then you can easily afford the dock fees.” Wrong! Talk to anyone who owns a sizeable boat and they will tell you that those fees sting, and they will do anything to avoid them; many boaters in FL will buy a house specifically because it has deep water dockage or it has space in the back yard (or adjacent to the garage) to store a boat. If you own a house with dockage but don’t (yet) own a boat you can easily rent out your dockage space to a desperate boat owner who is trying to avoid sky-high commercial dock fees for a nice monthly income.
In my dreams the biggest boat I could imagine owning is the Predator 92 Sport.
