Welcome. Like anything, it can be an expensive hobby. But buying and operating a modest sized boat need not be terribly expensive. If you're willing to do your own work, you can economize quite a bit. A side benefit to owning a more reasonably sized boat is that you can ignore all the threads on sailnet related to TV's and microwaves.
