  • This video shoes the construction of a single composite racing canoe by resin infusion. It is unusual because it uses eight different reinforcement fabrics including flax and jute, in four combinations using two different types of epoxy infusion resin.
    It is a demonstration of how different laminate combinations perform within the same product.

    Interesting use of Soric for the overlapping tape

    • @darksidecanoes7053
      @darksidecanoes7053  3 роки тому

      I don't usually use Soric in this way along the keel line, I usually use it for ribs. However the whole point of this concept boat was to enable the comparison of the different laminate combinations in terms of stiffness and strength.
      If I'd used Soric for the ribs, it would have undermined the purpose.
      Great stuff though!

    Nice to see the detail of how you put this together - especially things like the jointing of components and bonding in parts.
    The only thing I am confused about is that you seem to use different materials on the left and right side (e.g. spread tow twill Vs. Carbon kevlar), or am I confused between top and bottom?

      Hi Karl, the point of this boat was to show a number of different combinations of fabric and resin. I can't afford to make four boats so I did four in one.
      My frustration is that there are no perfect combinations because it is a compromise, so which one is the best?
      It is to stimulate debate.

Ric h ard Fox K1 Slalom & Martin (Bushy) Hedges C1 Slalom who sadly passed away in a car accident. There was another terrific guy , pretty sure he name was Keene who also paddled C1 Slalom.
      I represented Australia C1 Down River & C1 Slalom. The best in the world 4 C1 Slalom 1979 for 10yr + were the Americans by along way . They had an awesome coach, Bill Endicott. And the best Australian K1 Sprint Paddler was John Sumegi . He came 2nd '79 Worlds & '80 Olympics. Gaybo Canoes built my C1 slalom boats & C1 D.R. boats .
      Think they r out of business these days . Pretty sure the best boats from all those disciplines come out of Europe these days .

    Interesting parting line and only a half-lap joint on the inside to bond the two together. Intuitively I would have gone for a top/bottom split instead.

    • @darksidecanoes7053
      @darksidecanoes7053  3 роки тому +7

      Joining the boat down the centre line reduces the length of the join and also provides an opportunity to stiffen the lower hull join.

    • @darksidecanoes7053
      @darksidecanoes7053  2 роки тому

      Now that's the $34,000 question! Each combination is right and there are dozens more that are equally good, but how does one know which is the best other than to try them all.
      I wasn't keen on the "green" fabrics as they don't look great and don't "wet out" consistently.
      The material cost are probably the smallest part of the overall cost as it is labour which is the biggest component which is why I never understand why customer opt for the cheapest fabrics.

      You need a mold, but it seems to be pretty interesting if you are not doing a unique piece and are doing more than one. In the video I saw they use it on a small hull.

    I would like to see someone dimple the bottom of one of these for drag reduction. I had ride on a dimpled kneeboard years ago and you could turns sideways and skid yourself back towards the boat whilst underway, just a guesstimate there was about a 50 percent reduction in drag.

      The question is, how do you create a consistent pattern across the whole boat surface? The concept is similar to a shark's skin.
      Some paddler have tried to roughen the surface with sandpaper but it just produces a series of random scratches.

      @@vspetkov I'm not great fan of Kevlar. It was invented back in 1965 and there have been other more modern products developed since, including Innegra and Twaron.
      Kevlar starts nice and golden colour, but as it ages and absorbs water it turns an ugly dark brown.
      I know it's used by many canoe manufacturers by I sometimes wonder if that is because they've always used it, or because they really do think it's the best.
