Keeping a boat in a marina can cost from $1,500.00 to $2,500.00 per year depending on the size of the boat and the marina you keep the boat at.
That averages out to around $125.00 to $206.00 per month for keeping your boat at a marina.
Owning a boat with all startup costs including the boat itself can easily cost you around $75,000.00 up front depending on the size of the boat.
