It's all relative.

The cost to take a Melges 24 to Key West Race Week is on the order of $10K. That's ONE regatta. Food / lodging for your crew, dockage, crane fees, etc., etc.

Of course, the boat set you back $65K to begin with.

Over the last ten years, I've spent an average of $6K per year on my "habit". That doesn't include parts - like sails.
