The U.S. One Meter Class is a developmental class, which means there are very few design restrictions. The basic design restrictions include, overall hull length, keel depth and sail area (see class specification for the few remaining restrictions). The unrestrictive nature of the specifications, encourages one of a kind Home Built yachts. The hull can be self designed or built from plans, and easily planked from wood. Or you can purchase a kit, or complete boat from one of several suppliers. The structure of the class specifications allows the designer/builder to experiment with a design, and then try it out on the water.

The One Meter yacht is light weight, very fast and responsive to the controls. It is a fun boat to sail. And inexpensive two channel radio is required for control of sails and rudder. The boat is easily disassembled and fits in a small size automobile, for transporting to the pond or lake. The U.S. One Meter class is one of the least expensive classes for the new skipper, just starting in the hobby of R.C. sailing.
