    The future is not as far away as you might think it seems. I'll be looking into this myself.

    Hmmm, though, as that article points out, few of us would save money by going down that route :

    "For the owners of these converted yachts, it’s not really about saving money. As the EU-funded Hymar project revealed, there aren’t many cost savings involved with fitting a hybrid system, mainly because the kit remains relatively specialised, and still quite expensive. Instead, it’s about the joys of gentle, silent cruising with zero emissions, minimal ongoing maintenance and a large reserve of electrical energy for domestic loads."

    The cost of hybrid systems is very high and most sailing boats don't use that much fuel, so you are going to take a long time to recoup the costs, let alone save money. Mobos do burn a lot of fuel, but they also require very high levels of thrust - beyond the technologies being discussed there.

    Mobos yes but then, you don't go into motorboating for environmental reasons. Sailing however is pretty environmentally friendly can be completely sustainable (even with GRP) by replacing the diesel engines with electric engines and you wouldn't have as much cost with re-charging either (although fuel cells may very well be slightly more expensive).

    These guys in Australia did it because it was cheaper than replacing the engine:

    Lets turn this thread from "Goodbye red diesel" (Regretful) to , "Good riddance diesel!" (Positive)!

    You won't very rid of the fundamental idea because as i have already comprehensively covered elsewhere the costs of a fully compliant bunded fuel tank is relatively low (albeit not as low as the numbers you've pulled out of thin air) and certainly economically viable

    Any location already selling red diesel will already have all the necessary compliance systems and permissions in place (excepting possibly planning permission which may or may not be required depending on the location)

    Such "off the shelf" bunded tanks are common being widely used in construction, plant hire operations, commercial vehicle yards and, surprise surprise, marinas including the marina where we're based

    So i wish people would stop inventing fallacious excuses for the UK marine industry failing to even begin to implement solutions to this problem despite being given ample time to do so
