Does someone make a J-Class yacht kit?
This answer depends on what you mean: There is currently only one manufacturer of a model J-Class yacht that floats and can be controlled with a remote, that information can be found here. There were three other hulls produced in fiberglass which were the Enterprise, Whirlwind, and Ranger. These are no longer in production. There are several manufacturers of non-sailing models of J-Class yachts which your local hobby retailer can help point you to.
