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.

Sea Queen will have the wheel chair motor, with Mtronks control.
Joilie Brise is having a new ballast keel cast to lowere C of G and Improve sail power.
- frankburgessMaster SeamanThanks for the ideas fellas,....as the motor was given free I will try it out with just brief runs and check the motor temperature.....I'll let you know the outcome
- frankburgessMaster SeamanWell fellas, Sucess the boat performed pretty well, similar performance to the motor which burnt out, but without any drama. Checked the temperature of the motor occasionally, and it seemed warm but not excessive. The battery is a 7amp lead acid (Motorbike type) and gave well over an hour running time.
Unusual feature of the boat, is that being big (46") the wash is considerable.
Thanks for your ideas
Best Regards
frank
Model is 65" long with a beam of 10". Power is by electric running via a gearbox at 300 rpm. Ihave taken almost 2years to complete the model working most days on it. Attention to detail was the order of the day.
I am using a Planet T5 Tx and Rx, 5 channels. I have a smoke generator pushing steam out of the twin funnels,synchronised to forward speed, faster the revs, faster the steam. Conventional rudder operation.
Have an operating Radar, ships horn, simulated steam noise varies as speed is altered, full navigation lights,all cabin lights can be switched on and to keep the 106 passengers happy I have a Banjo Band playing to complete the scene. Have sailed it recently at Peterborough and performs really really well. Have to say it tends to attract a lot of interest.
I am now constructing the Ayton Cross tug in 1:32 scale, with all the detail I want.Plan is to tow the Jeanie Deans around when completed as well assailing her
The first, rebuilt by Kalamunda, is brushless with NiMh cells and the second, having it's first sail since being rebuilt by Ian Gardner, has a Graupner 700 with 3s Lipo's (in parallel) on a 37.5mm X type prop- Electronize 30amp esc.
I think these are lovely looking old boats designed by Les Rowell of Aerokits fame, and obviously based on traditional cruisers from the Norfolk Broads- see Martham Boats, where you can still hire a wooden craft like these, although you'd definitely have the river inspector after you if you sailed up the Thurne at these speeds!
- ianed57Sub-LieutenantHI Graham,
Glad you liked the video. They are smashing boats aren't they? I really fancy a new IP Engineering one but have too many other projects on the go to make it a sane decision!
I have to say my WM is the best running of my faster boats, which include a Lesro Sportsman and a Rapier. She seems to hug the water in turns rather than bounce around, so a great design I think. I'd be interested to hear how you arranged you gearing on your WM. Did you make it up or but a ready made unit?
Ian - jelley_babyChief Petty Officer 1st ClassHI I bought them on Ebay, from Hongkong, they were about £9 plus some small amount of postage they have a brass motor gear, and an aluminium gear for the propshaft I use the system on three boats the Wavemaster a Sea Commander and a Fire Boat. On the water with 7.2 volts but will also run on 9.6 volts and 11.1 volts 3 cell lipo's. I will try and get a photo of the motor and gearbox. Regards Graham
The model was scratchbuilt of balsa strips and aircraft plywood, using official USCG blueprints. Powered by a 6 volt motor and a 2 channel radio, the Chatham lifeboat is pleasure to run in my local pond.
- Ian_BurgessRecruitThanks Mike, I must try balsa. Just now I'm using 3mm pine planks which take some clamping while the glue dries. Like you, I resin wash the finished hulls inside and out.Regards, Ian.
First sail 16-12-2012 Cwmbran. First fitted a too powerful Outrunner with a small rudder no good would not steer or go straight. so changed outrunner to a lower rated one about 1200 kVA and fitted a larger rudder (medium size as opposed to a small one). The result was very good and she ran all morning on a 2 x 4.8 Volt 3800 MAh Nimh in series 9.6V total, for about 2 hours.
- jonbliss152Master SeamanHi, I'm currently in the process of building my first model. it's one of my fathers that has been sat in the loft, kit form for 30 odd years. I have the decals to turn it into a fire boat but I'm struggling to find a suitable monitor to place on the coach house roof. Can you remember where yours came from?
- jelley_babyChief Petty Officer 1st ClassHi, it's not a proper monitor on the cabin roof, but the spray nozzle from an air freshener the type that are battery powered and spray one burst every 15 minutes. I suppose that you could attach a small pipe to it and make it into a working monitor if you wanted too. Hope that this helps Graham.👍
- seafarerPetty Officer 1st ClassLove the sound track! pity about the bluring but I guess that the wind had a part to play.....nice videoLiked by Brightwork
