According to Boats of the United States Navy, a Navy boat is defined as an uncommissioned waterborne unit of the Fleet, not designated as a service craft, and capable of limited independent operation. It may be assigned to and carried on a ship as a ship's boat or assigned to a shore station or a fleet operating unit. The 26' Motor Whaleboat's purpose was to transport personnel and for use as a lifeboat.  The boats had a crew of 2 and a capacity for 22, including the crew.   They were, as the name suggests, 26' feet long, with a beam of 7' 4".  They had a top speed of 7 knots, and with a full complement of fuel (28 gallons), had a range of 110 nautical miles, at full power with a full load. 

As mentioned, there are three boats included.  The detail and fineness of these boats is really terrific.  There is a well defined helmsman rail, a rudder, and a prop.  There is also planking detail inside the boat, along with a well defined combing around the edges of the hull, and a strake along each side of the hull.

 This is Black Cat Models set AC700021b, US Navy 26ft Motor Whaleboat Mk1 (x3).  It retails for about $5.25 USD, and is available directly from Black Cat Models - who I'd like to thank for this review sample - or from some of our other fine sponsors.
