Post Subject: Generator

Hi - we have a Ruston Hornsby 2VSH with a BKB generator attached to it on our 25yr old boat.We have been lead to believe that it was never used.We have no idea how to use it but in this climate of ever increasing bills we thought it would be a shame not to put it to good use - perhaps to run immersion heater and washing machine.Its run by two belts via the engine as far as we can tell. Do you think it would be useable and can anyone tell us how to operate it? If its unusable what would be the best generator to fit - preferably one that isn't attached to the engine? Many thanks in anticipation.

Dear Sharon. I have no idea if this is an AC or DC generator without seeing all the details that should be on a plate fixed to it somewhere. I also do not know if it needs any external control gear. If it is an AC generator it is likely that you will have to run your engine at a single, steady speed to produce the correct number of cycles (50Hz. Many things will work with quiet wide variations but they may get hot and not perform as expected. some things may not work at all or even possibly be damaged. Personally I would not try to run a mains machine that has been left idle on a damp boat for 30 years. At the least it needs a competent specialist to have a look inside it and pass it as safe. There is an address for BKB in Birmingham, but it might not be the same company. It sees they may have merged with a larger concern. I found both bits of info via Google. I think that most people today would go for Travelpower system. With a rigidly mounted engine, as I am sure yours is, it could be mounted to the boat's structure and driven by a removable belt or belts. However if suitable pulleys are available for your engine I have no idea. The existing ones may even be OK. The Travelpower produces the AC electronically so is not speed dependant for frequency.

Many thanks for your prompt reply Tony! I think it best if we obtain a new generator so will look into the Travelpower system. Are there any diesel powered generators which aren't dependant on running the engine?

Dear Sharon, Loads. From diesel powered open frame "site" generators through to number of open and acoustically enclosed (cocooned) generators designed for permanent installation in boats. The open frame ones will be heavy and noisy and the cocooned ones will be fairly expensive. A cheap marine one will be broadly similar in price to a Travelpower (say £2500) and unless you decide to use your well deck or hang it off the back of the boat I think you will have a problem accommodating a generator. Please also consider the likely life of the smaller generators and the cost of routine servicing. Further to my first reply - although the frequency of the Travelpower output is not speed dependant the output power is, so do not think you can run any electrical device with the engine at tick-over.
