INTRODUCTION

M.T.B. "Gribb" Royal Norwegian Navy jpg (49081 bytes)

The "NASTY" class has been developed and introduced by Boat Services Ltd. A/S, Oslo, in close cooperation with experienced officers of the Royal Norwegian Navy, serving on Fast Patrol Boats during World War II. 

The boats are being built by Batservice Verft A/S, Mandal, belonging to the same company- group. The Chief Designer is Naval Architect Jan H. Linge. 

The prototype "NASTY", from which the class derives its name, was designed and built entirely as a private venture and was completed in the autumn 1957. In the spring 1958 the Royal Norwegian Navy ordered their first 12 boats and the type has since been in continuous production for deliveries to the following navies: 

  • The Royal Norwegian Navy, 
  • The U.S. Navy, 
  • The West German Navy. 

According to naval staff requirements the "NASTY" class boats may be constructed as motor gun boat, motor torpedo boat, mine layer, submarine chaser (ASW) or combined versions of these. 

The boat is powered by two 18 cylinders Napier Deltic diesel engines, each of 3100 Bhp, supplied by D. Napier & Son Ltd., England.

 The extremely beamy hull -- length/beam proportions being slightly above 3 : 1 -- incorporating a V-bottom hard chine after-part and a round-bottom fore-part gives a maximum of speed with the ability to carry heavy loads combined with good seaworthiness and maneuverability

. To attain the highest possible strength with a comparatively low weight of hull, the structure with longitudinal girders, bulkheads, web frames and frames has been designed according to the most modern methods of construction. 

It is generally considered in naval circles that the "NASTY"-class has fulfilled the expectations to a fast seaworthy fighting unit considering the reliability, range, speed, economical running, maintenance and relatively low purchase price. 

For further details concerning the boat, please refer to the specifications and illustrations in this manual.
