ride in models

This is worth a look and there is others in the same type.Some kids have good dads!

Jumna ride in paddle tug Western Australia

Where is the little Western Australian  Jumna today?
http://www.paddleducks.co.uk/smf/index.php?topic=769.0

I have been researching "Jumna", a paddle wheel steam tug boat which operated at the turn of the 20th Century in the small port of Littlehampton, Sussex, UK.  The Curator of the Littlehampton Museum recently sent me a photocopy of an article from a modeling magazine article dated August 1980.  Here are the first three paragraphs of the article which will clarify things.

    "Today, the little tug "Jumna" sits almost forlorn on the verandah of the Busselton             Museum, where people come and go and take away a photo of a once proud steamship.

    "Jumna" first saw light in the imagination of a young boy in England when his eyes observed the real "Jumna" assisting vessels in and out of the Port of Littlehampton on the South Coast.

    Canon, or as he was known as Rev. Robert Davies, came to Western Australia and started his training in the ministry of the Church at Bussleton."

The article describes him as one of "Australia's most prominent model engineers".  He apparently built a 12' 6" fully operating replica of "Jumna" which was powered by a live steam engine and was large enough that Rev. Davies and a passenger could ride in the model itself.  The author of the article was Keith Watson and it appeared in the August 1980 issue of "Live Steam" magazine which appears to be an American publication out of Michigan.

The author describes the construction of the model which apparently took place in the Busselton Rectory and it's quite detailed along with drawings and technical information about the live steam plant.  It seems he knew Rev. Davies and describes in some length a trip he took in the model.

    " To ride the "Jumna" was an experience I shall never forget, and goes back to the late 1950's when I had the good fortune to meet Canon and his wife Dulcie, who shared his love of steam."

It seems this model was very well known in the town of Busselton as must have been it's builder, and apparently even once transported the Prince of Wales during a Royal visit.

It would be fun to locate the model and re-establish it's connection with the Museum at Littlehampton half a world away. It's even possible the Rev. Davies is still alive today as "Jumna" operated at the Port Littlehampton up to around 1914.

Any help in tracking this down would be appreciated, Derek, and as always, very best regards.

manned or unmanned

USVs are an interesting field these days. Both Singapore and the US Navy are testing the Spartan Scout, an unmanned rigid hull inflatable boat which may prove useful to in-shore ship protection and anti-piracy missions.

Real ride on tug

manned models a good look

To the casual onlooker, it may look like a group of overgrown children sailing in rather extravagant model boats.
Manned Model Class - Mass Maritime AcademyBut, in fact, they are some of the shipping industry’s most experienced sea captains on one of the world’s most unusual safety training courses.
The lake in Marchwood, near Southampton, Hampshire, boasts a fleet of seven scaled-down model cargo ships on which veteran captains, pilots and senior deck officers can hone their skills.
The ships, which are big enough for two people to sit in, behave exactly like the real thing as they negotiate the 13-acre lake’s artificial channels and tides.
They range from a scaled version of a 300,000 tonne vessel that itself weighs in at six tonnes to a radio-controlled model tug.
So is this simply an excuse for taking some time off work to muck about on the water?

Good tug site

Turns out it is a model tug

Not a model but I like it.

Tug masters may get trained by a little BRAtt


01 Oct 2009

The BRAtt training tug will be only 7.8m long. The BRAtt training tug will be only 7.8m long.
Training potential tug masters has become a major challenge for the ship handling sector of the towage industry worldwide. With large numbers of modern ‘ state of the art’ tugs with omni-directional propulsion systems coming into service, the ability to train up and coming tug masters effectively and in suitable numbers has become an increasingly difficult task for many tug owners.
The tugs are more powerful, extremely agile, and in many cases are operated by a smaller crew. A large majority of those vessels employ Azimuthing Stern Drive (ASD) propulsion systems, enabling the tug to be positioned quickly and precisely in response to the pilot’s orders. Sophisticated, high powered terminal tugs, carrying out ship handling and escort work, often in environmentally sensitive and/or exposed locations, require even greater skills and a higher level of qualification. Gaining the necessary skills to be able to operate these tugs safely and efficiently is a matter of training and experience. A mistake can rapidly result in disorientation and damage to the tug or its tow.
The subject of training tug crews is one that frequently crops up at conferences, towage association meetings and around boardroom tables. Operators with tugs operated by just two or three persons have very little opportunity to train crew members from scratch without creating supernumerary posts for training purposes. The traditional route of promotion through the ranks has become much more difficult. Using full size, expensive tugs for training new operators is inefficient, expensive, and exposes those vessels to significant risk of damage. Current options include the employment of highly skilled ‘training captains’ to carry out intensive training programe, and increasingly the use of realistic computer based simulators.
Vancouver based Robert Allan Ltd, in collaboration with Burchett Marine Inc, have joined forces to propose a unique solution in the form of a small scale, fully manned training tugboat which could ultimately be fitted with a variety of alternative propulsion systems, thus also qualifying as a legitimate test platform for proving unique new power supply technologies.
For a number of years the Principals of Robert Allan Ltd and Burchett Marine Inc have been discussing the potential for designing and building a lower cost, ‘drivable’ scale model tug to use as a training vessel. This boat would have to be large enough to be very realistic and fully safe in all training operations, large enough to have real time response actions, be powerful enough to perform some ‘real work’ where the situation warrants, be fully Class certifiable if required, and be small enough to be road transportable.
The result of those deliberations is the ‘BURCHETT-ROBERT ALLAN training tug’, hence the BRAtt. The standard vessel is currently at an advanced stage of design development and will measure 7.80m in length with a beam of 3.60m. A representative ASD hull form will be used, with twin fully azimuthing ‘z-drives’. Initially the tug will be offered with a diesel power plant generating a total of 236 kW (316bhp). Other principle features include all-welded aluminum construction, a fully operable forward winch and all round resilient fendering.
The vessel will provide a relatively low cost option that would avoid tying up full size vessels for training purposes and the associated risk of damage. With an intensive, effective, skills based program potential tug masters can be trained much faster, more effectively and at reduced cost. In many cases the little tug can be utilized for minor towage and harbour work, resulting in some cost recovery.
The introduction of the first little BRAtt is rapidly becoming a reality. The first vessels will be built in British Columbia. A nominated ‘licensee’ builder has been identified for the North American market and a ‘kit’ option is envisaged for the overseas market. In time it is likely that the BRAtt will also be used as a platform to demonstrate emerging power source technologies such as hybrid propulsion systems and fuel cell technology.
