After the end of the war the Royal Navy decided to move from gasoline powered fast launches to diesel, to reduce fire risks.
The first major diesel powered boat class was the Dark, introduced in the mid1950s. These were powered by two Napier Deltic horizontally opposed, triangular layout two stroke diesels.
Shortly after this class was introduced it was determined the role of the Fast Patrol boat had been superseded by helicopters and aircraft. The Fast Patrol vessels were then gradually withdrawn.
To retain competence in the use of fast vessels, the RN commissioned three fast training boats (FTBs), the Scimitar class. This was the last high speed RN class of the era.
They were similar to the Brave in many ways. Both were built by Vosper and the lineage is evident. Rather than three Proteus gas turbines, they only had two, although with CODOG diesel units for slow speed operation. They were unarmed and designed to give R.N. crews experience in fast, coastal patrol boats.
The vessels could be armed and converted to three Proteus turbines if circumstances changed.
Our COVID lock-down hastened progress on my Dark class project, so have been trying to find another build for the coming winter. Have decided to model fast patrol type vessels for the time being. They are great fun on the water.
Would have liked to build a Scimitar Class FTB in around 1:32 scale, again using a GF hull from MTB Hulls, but that scale was not in their range. A GF hull is light and robust, well suited to these vessels. MTBHulls did offer a 1:72 scale hull, but that worked out around 16.5” long. Thought it would be too small for a working scale model.
Was in touch with a modeller in Australia who has made similar models. He also pointed out the number of successful “plastic magic” conversions of kits that are around this size. Obviously, it is achievable. Would give an unexpected change as the larger scale would have been similar to my recent Brave Borderer and R.A.F. RTTL projects.
The biggest challenge will be to keep the weight down to around 450g.
Looked an interesting and challenging project and at such a small scale one with plenty of potential for failure.
