I have just completed my Puffer and am quite pleased with the outcome. The components are quite good but do need a bit of fettling but this is what our hobby is about. This is my third Caldercraft build so I am used to their quality and sparse instructions.   As usual for Caldercraft you need to have your thinking cap on as the A0 plan and the 'instruction book' do not match up but of course they do expect you to have a little bit of experience in model building. it has taken me about 6 months to build working on and off over this time. it has a large hull which is easy to house the motor, ESC, RC and batteries, etc. (I installed 2 lead acid 6 volt batteries, one on each side amidships) which gives stability and ballast. Being a large deep hull it needs a lot of ballast, even in its short length.I have only tested her in the big white nautical test facility at home so do not know how it will perform on our lake but hope to try it out on Sunday if the weather is set fair. Tried her out Wednesday and she sailed really well - maybe a little more ballast in the bow but not too concerned.

Both these models are scratch built Durban tugs in 1:48 scale.

Built J.R. More between 2011 and 2012 and is 41 inches in length. The original oil fired tug was built 1961 on the Clyde and was one of the last steam tugs to be built on the Clyde. This tug still exists at the Durban Museum and is undergoing restoration.

Started Sir William Hoy in 2013 and is 45 inches in length and I am still working on the fittings and finishing. The original coal fired tug was built 1929 in the N.E. of England.
Both model tugs have twin motors geared down 6 to 1 and have differential steering.

The Strathclyde University sponsored a modellers competition to encourage school pupils to design an R/C model yacht. When Graham Bantock the noted designer - visited the event to give prizes, he decided to design a boat of his own and WEE NIP, this boat was born.

See forum and my harbour (CapnJim) for more details.
Just some footage of my weathered Model Slipways Puffer - now some years old but still cruisin'. Still appreciating the model and is one of my favourites. One day I'll build a puffer at 1/32nd. but for now this does very well.
Easy build but lots of opportunities to add detail. This has all the bells and whistles (well 'steam' whistle, smoke generator and puffer engine sound at least). Would fit in a briefcase but still able to stay afloat against the wash of bigger boats or blustery winds. Surprisingly, steers well when going astern. Speed with supplied motor about 2mph ' but this is faster than scale by a margin.
Clip prepared for YouTube resolution so best not viewed full screen.

Super little kit making a great model. Essentially styrene with added mixed fittings then super detailed and weathered.

Video rather shaky as operating camera with one hand and RC with the other - will Improve and add soon.

This Model of the J. R. More tug which was one of the very last large Steam Tugs built on the Clyde in 1961.

Scratchbuilt from the 1:48 scale plans of a sistership the F.C. Sturrock with various modifications for J. R. More. Powered by twin 12v geared motors.

The J. R. More Tug is a large tug and still exists as a Museum exhibit at the Durban Maritime Museum and well worth a visit in South Africa.

My thanks to Keith Marks who was a Master of J. R. More and the F. C. Sturrock among others for his photographs, help and interest during the construction of this model and is now a good friend.

This video was taken at the Sumner Ponds which is used on alternate Thursday by the Southwater Dabblers MBC.

Video is not very good quality but will remake with a better video.

Model Slipway kit - super detailed. 2CH RC with mixer to provide engine, whistle and smoke. 1/48th scale.

Excellent kit fitted with ACTION electronics.

J. R. MORE - LAST OF THE LARGEST STEAM TUGS BUILT ON THE CLYDE. The best looking tugs ever built!

This model is scratch build at 1:48 scale of the SAR&H Durban tug J. R. More, which was the last large steam tug built on the Clyde in 1962.
It took over 2 years to complete this model, which was my first scratch build from the modified plans of a sister tug called the F.C Sturrock, which was also stationed at Durban as the shift tug for that harbour. Other tugs of the class were also stationed at Port Elizabeth and Cape Town.

The J. R. More was the newer day tug in Durban, most often used to service the Union Castle ships and others in, out of Durban and remembered by so many visitors to South Africa of that time.

This model tug on the water has differential motor control, software linked with the rudder, can go about on the spot and a delight to sail as a model, capable of 6 or more hours on the water. Working Rotating Radar, lights and woop-woop sounder as per the original tug. I would also like to install the Telegraph bells, however these would drive fellow modellers to distraction, as they were a very distinctive sound and very regular, Implanted and well remembered by the crews and those in and around the harbour, even today. The engines on the other hand were almost quiet and by all accounts very reliable.

This model is ballasted mainly by two 7 Ah 12 Volt SLA Batteries for the main drive motors and a 2 Ah 12 Volt SLA (Aft ballast) for the Lights, Radar and Sound unit. All up weight is 14Kgs and capable of above scale speed from the two MFA 6:1 ratio Geared Motors driving two 4 bladed 70mm screws.

This model has onboard charge regulator circuit, built-in minature dual volt meter to allow quick on-board voltage inspection and single plug-in charge and regulator socket for charging all 3 Batteries together.

The actual full size J. R. More tug still survives and can be visited at the Durban Maritime Museum in Durban, South Africa. Local supporters are undergoing essential repairs, restoration and preservation with private and company financial support.

J R More is the only surviving large steam tug left of this class and as Important to the skills of the Scottish shipbuilders of the Clyde.
