The Smart Trawler 50 is a full displacement motor cruiser based on successful traditional North Atlantic working craft hulls. It is designed for unrestricted ocean use and extended offshore cruising. The vessel is built to ABS and Lloyds scantlings with a steel hull construction and aluminum superstructure. It meets applicable ABYC standards. The Smart Trawler 50 provides sea kindliness, handling ease, easy maintenance and operational economy.
Hard chines and a substantial keel minimize roll and a bulbous bow reduces pitching and improves fuel efficiency. Two longitudinal fuel tanks keep the weight low while minimizing free surface effect providing a more comfortable and stable ride. Optional stabilizers can be added.
The vessel is subdivided in four compartments by three water tight transverse bulkheads; a collision bulkhead isolates the forepeak, a bulkhead with a water tight door separates the lower accommodation area from the engine room, and a bulkhead with a water tight door isolates the lazarette.
The vessel is powered by a 360 bhp, Series 60 Detroit Diesel with a ZF 350-A reduction gear. The engine is electronically controlled and meets even the strictest California emissions standards while extending a high level of fuel economy. The vessel’s hydraulic system is driven off the main engine gearbox and powers the bow thruster and windlass and provides two additional hydraulic ports for equipment such as davits and stabilizers. All equipment and hardware were selected to be tough, reliable and readily available.
The engine room is large and well laid out with easy access to all equipment and systems. The pilot house is spacious and provides all round visibility. Weather tight Dutch doors in the pilot house further improved visibility during docking maneuvers as well as providing excellent ventilation. The wide walk-around decks are uncluttered and well protected. Safety is a foremost design consideration.
The boat is heavily insulated throughout for thermal as well as acoustic benefits. There is an aluminum deck head in the engine room and a second deck under the salon/galley. This provides a dead air space and heavy insulation between the machinery and accommodation areas which mitigates noise and provides fire protection equivalent to that found on commercial passenger vessels.
Bulwarks are plated inboard as well as outboard which gives a clean profile and eliminates high maintenance stanchions and framing. All windows and exterior doors are coast guard approved for offshore applications.
Interior partitions are constructed of 1" x 2" steel supports and sheathed with marine grade plywood and high quality laminates. Cabinets and interior joinery are constructed from indigenous hardwoods and have a natural finish.

The Smart Trawler 50 features an upper level salon, galley and pilot house and lower accommodations with a master stateroom, double cabin, and a workshop/office area. The interior features the Mediterranean layout with a curved stairway from the pilot house to the accommodation. The workshop/office area can easily be converted to a third cabin with several layout options. One head with shower is located between the master stateroom and the double cabin with access to it from the central hall. A second head with a shower can also be installed. The head features a Vacuflush toilet, sliding shower door, Surell vanity top and ample storage cabinets under and behind the vanity. The salon has a U shaped settee and a spacious U shaped galley area. There are ample cabinets in the galley, Surell counter tops, a S/S double sink, an LPG stove with an oven, a fridge/freezer, and microwave. Lined curtains cover the windows in the salon and the port lights in the lower accommodations. The pilot house is on a higher level than the salon to allow for 360 deg. visibility. The interior has air conditioning and electric heating. The cabinets and interior joinery are all solid wood (maple) or premium grade plywood. Walls and ceilings are covered with laminate veneer over @ plywood. The ceiling of the pilot house has a textured metallic surface to reduce reflections and provide good light distribution. Hanging lockers are located in the staterooms and the salon area.

The vessel has a 24V DC system with separate battery banks for ship services and engine starting. DC power is supplied by a 100A alternator on the main engine and a 65A battery charger. A 24V to 12V power converter provides power to the VHF radios, the depth sounder, a power outlet in the pilot house and some instrument lighting. AC power is provided by a 20 KW diesel generator. A 240V, 50A shore power service feeds a 15 KVA isolation transformer and 120V/240V power is available on the vessel. The air conditioner, water heater, bilge pump and other heavy loads are 240V. A 2500W inverter provides 120V power to separate AC outlets and the engine room lights so that if high load AC equipment is inadvertently left on it will not drain the batteries. When AC is available to the inverter it bypasses up to 30A to the output rather than drawing power from the batteries.
