Trawlers are most often offered in lengths ranging from 35 to 60 feet (or more) long. Most are built for long term cruising of regional and worldwide destinations. Combined with large fuel tanks they can cruise far before needing to be refuelled. They can be home for between 2 to 8 persons for many days and can be a permanent home.
Usually trawlers have a single engine, though twin engine installations are also available from some builders. They have a large fuel capacity. Fuel range is normally 1,500-3,000 miles on smaller vessels, even greater for those over 45ft in length. When combined with the slower speeds of a displacement hull, these features give such vessels far greater range and economy than similarly sized planing boats. A large engine room under the main cabin is another feature of true cruising trawlers. Many also include a diesel generator of 5-20kW to power domestic appliances, bow thrusters, dinghy cranes, and similar equipment.
