  1. except that spirit levels - the basic tool for all built in features - don't work in a floating boat. I would recommend the exact opposite.

  3. Luddite. you are past your sell-by date. on that basis you won't be allowed to row, paddle or pull your boat unless you can devise a Bizzard-type scheme to contain all your effluents and recycle them for ever after.

  6. have you ever checked on where council tax money is actually spent? https://www.local.gov.uk/sites/default/files/documents/A4 STATIC IMAGE_04_1.pdf nothing to do with the size of your house, it's just an assumption that those in big houses can afford to pay more. you are paying for the privilege of living in a community, with all that that entails. of course you could beach your boat in a mud berth on the Isle of Sheppey and pay nowt if you don't want to live within a community. you can't opt out of paying for social care, for example, just because you live on a boat, any more than I can because I don't need to avail myself of such care.
  7. there must be abandoned farms in the area where you could rent a space in the yard and possible the farmhouse or a caravan space.

  10. this is also worth reading if you are interested in light electric craft: ELECTRIC OUTBOARD DRIVE for SMALL BOATS A Do-It-Yourself Handbook July 15, 2010 by Todd Wells I downloaded it as a PDF for free. it deals with 'freight canoes' and other small boats on U.S. lakes and rivers. it is a mine of information. there is an Electric Boat Association that seems to be inactive but last time I checked they still had some advice notes that you may have to pay a subscription for. they largely deal with river and lake launches with inboard motors, but the advice on hull design is clear.

  12. how wide are traditional narrowboats in Manchester for god's sake? the man's either a liar or a midget. ONLY a couple of metres taller? does he comprehend when the word only is appropriate unless he is being sarcastic? "boats" like that should be offered a free lifetime mooring on the tidal mudflats of the Isle of Sheppey, so that the tossers cannot claim to have been left homeless.
  13. OMG I'm 30 years ahead of the game !! ................ actually not quite true 'cos next year I plan to reintroduce my 2hp Johnson 2 stroke as an auxiliary, both for a bit of fun (how fast can you drive a canoe hull?) and for use when battling against wind and current (in my case typically when negotiating Henley Reach going upstream).
  14. lbs thrust is the best measurement of any outboard because it measures the actual force that drives the boat (taking into account that the lbs thrust is measured in the static condition and when the boat is moving things will be slightly different because the propeller is operating under different conditions). hp measurements are the power of the powerhead and do not take account of any losses in the transmission and the propeller efficiency. for the record, my 40lb Minn Kota should consume 500 watts at full throttle, but actually draws 30amps or about 350 watts. that produces a speed in still air and water of 5.3kph. the boat was specifically designed for low drag and has a waterline length of 20ft, maximum beam on the waterline is 3ft (actual beam at the gunwale is 5ft), displacement is 600kg and the hull is very fine with a very shallow transom. next year I will experiment with a higher pitch prop but any increase in power consumption needs to be balanced against the speed improvements because in my case the range (distance and/or duration) is critical. I would never want to use an electric outboard on a hull that wasn't specifically designed for low resistance. a typical cruiser has a wide and relatively deep immersed transom that will create a lot of resistance (the turbulence that you see behinds a typical cruiser is a sign of wasted power). your hull should ideally be as close to a canoe shape as possible. there are several formulae available to find the resistance of a boat when moving through the water (a measure of skin friction plus wave making at any given speed) - google boat hull drag calculation and take account of the unfair shape of your hull. an electric outboard providing say 50% more thrust than the calculated resistance should do just fine. this article makes interesting reading regarding hull shapes: https://arxiv.org/pdf/1803.10695.pdf 100watt panel approx 100cm x 50cm. 10kw is unrealistic unless you have a dutch barge of huge widebeam.
