Racing boats, usually together with oars, riggers, and other equipment for rowing, are stored in specially designed storage areas — or boathouses. These usually consist of a long two-story building, in which the boats are stored on racks (horizontal, usually metal, bars) on the ground floor with a large door at one end which most probably leads out to a pontoon on the river or lakeside. Other equipment is stored around the boats. Upstairs, there is usually a gym, bar, an area for relaxation, or, rarely, more storage (due to difficulties transporting cumbersome rowing equipment upstairs). Boats are conveyed to competitions on special trailers accommodating up to 20 boats.
