Yaw'll want to try Radio Yachting.
Various classes of yachts & most are "reasonably" priced.
Fr'instance...
An IOM (One Metre) club boat will only set you back about $1,000 to $2,000 but a really competitive boat will be around $3,000 to $4,000.
Then, we get into the Marblehead class. (Next one up.)
These can cost you up to $8,000.
Of course, they can cost a lot less if you build them yourself.
They may not be quite as noisy or quick as those cars, trucks & planes but the
excitement factor has to be experienced to be appreciated.
+ You get a lovely sun tan at the same time.

ps. This does not include the cost of the Tx, Rx set or the sail winch & servos etc.
