I think you really have to do your own math on this. Different areas of the country have different costs for the same thing. A new boat will require less in repairs than an older one, but an older one is less expensive. A new or newer boat will have a warranty. Single engine boats cost less to operate and maintain than twins. Dry storage can cost a lot less than a slip or rack storage. Purchasing a used boat that has been well maintained will cost you less when you get it than one that has been neglected. As someone mentioned, you can do your own maintenance. A smaller boat is less expensive than a big one. A faster and/or more expensive boat will cost your more in insurance.
