Well the story so far , I was too late last season because it was part built so I had a carbon effect wrap which looked OK, but tended to bubble in the heat, then in the course of learning to sail it I put a few holes pretty much everywhere, hull, deck foredeck so it had to go back for a bit of tlc last October, it's been a long wait but check it out, should be ready to fit out next week, I'm going for a red keyline on those rails and this time it'll get proper kitesurf straps and will look the absolute DON!

What you trying to do? Pop my bubble?  The bolts at the back I think have been sorted, doubt they'll do anything about the boom, the foils have all been sorted, not that they were rusty or anything, I've asked for the gantry to be increased in length.------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

Looks good - will be interested to see how it looks in 12 months as I had planned to do something similar with my next H2 but people told me the clear coat will get scratched and look scaffy. Looks good in the shop though!! ------------- H2 #115 (sold) H2 145 OK 2082 |

So, here's an idea I'm thinking about. I'm trying to convince folk I come in contact with on the option of a 'kit' in carbon, to bring the self builders into the now. There is already a ply self build thing going on with the Farr and several folk have built their own, but, they end up like my first iteration, wood and whatever you think about it, wood needs looking after and is more susceptible to idiots like me puncturing it with our harness hooks. OK carbon might get scratched but it should be more resistant to puncture and the price of carbon is so much more reasonable now especially in sheet form.
Does anyone think there would be an appetite for a self build class for kids, if there were say significant prize money at say a national event once a year? Obviously Dad would have to help, but this boat is ideal for youngster moving into the realms of trapeze sailing, I wonder if such a carrot might help a)Getting kids into actually building things and b)growing this class a bit. Just a thought. It's an absolute joy to sail once you get the knack and being on the wire is a great relief from knee and back pain from hiking hence it's appeal to us oldies, I dunno, it just need some sort of shove to get wider appeal. ------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

Some thoughts for you ... Some of the builders in Merlins and Solos have used a ply foam sandwich, and spray paint the finished product. This gives the ease of building a chined boat with the weight and stiffness of FRP sandwich boats. You could go to someone like Jordan Boats to supply a CNC cut set of parts, which could include part numbers cut into the parts, which would make the project less daunting. A class owned female mould would make the construction process much easier. ... hire the class mould, get the precut kit of parts ... drop them into the female mould ... apply epoxy fillets ... take to car spray shop ... job done Plenty of opportunity to customize with carbon twill or Fablon ------------- Happily living in the past |

The OK class in NZ has a lot of home built boats. There is a CnC cut file that you can buy and then get the parts cut and stick together yourself. I think some people have molded from this to make GRP boats, which appear quick - I think there were 5 or so of this design in the top 10 at the worlds. A carbon home build would be amazing though. No idea how hard it is in reality to do. I think you have to be very skilled and have vacuum pumps, etc. I tried making a carbon tiller once for my finn. It looked like a mars bar that had been left in the sun too long when it was finished! |

Respect to your commitment and very nice it looks. Some seriously high kick bars on the cockpit floor, are they any hindrance when changing sides? I only ask because Contender only allow in their rules one pair of quite small measured wedges.

Practically there is much less room in the Contender when tacking, anything more than a gnats cock on the floor will remove your knee caps, I suspect the rule is to prevent sailors from turning the boat into a torture device. Also I thought that rule referred to the gunwales to stop wedges becoming extenders? Expecting to be wrong though. ------------- |

I wouldn't say you're wrong, quite possibly reading another measurement rule. I looked at kick bars for mine because being very short in the leg it is a big step back from CB case to gunwale. There is in addition to a size rule, a rule governing the positioning of any kick wedges.

Sorry but 'faux' does not do it for me .... If it ain't a pig why put lipstick on it ? Racing boats are primarily about 'function' surely .... I guess each to their own - just make sure it does not get too hot and 'fry' the deck ...

ISTR a Contender with kick rails between the mainsheet tower and the back of the foredeck? That's where you need such things, as when it's marginal trap weather, you want your weight more forwards? Isn't all this naked carbon a bit old hat now? Reminds me of my 1992 motorbike.

The kick bars are a tad higher and thicker because I asked for it, the last ones were useless and broke anyway.
The carbon is real now rather than fake and will make the boat more stiff as well as better to look at. The red, is just a personal thing, I like a thin red keyline with an overall black device, it could be blue, it could be whatever colour you want, you just have to ask. That's the joy of this class, you can personalise things without becoming 'out of class'. ------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

Last year I built a Cherub a bit like this to a Clive Everest design. The deck and bulkheads were all made from CNC cut foam carbon panels and were bonded together with tape to make the shape. The hull was made on a male mould from loads of CNC cut foam panels which were sanded smooth on the outside before being laminated. If you were going for a more chined shape you could probably do it all with precut foam carbon panels and a reasonably simple jig. ------------- If it doesn't break it's too heavy; if it does it wasn't built right |

In some ways, in general, we are looking in the wrong area to make boats easier to build. The area that we need to make easier is the Mould. A CNC file for a click together male mold would actually take a whole heap of the worry out of what is an already sorted set of CNC hull build files. No worries about - 'is my boat going to be square' 'is my boat going to measure'. Because you are building over a certified CNC flat pack jig with certified CNC panels. Clive's Cherub design is a great one but is a design within a box set rule class. You can design a shape to fit a clever construction technique. Whereas the Farr 3.7 is a one design hull with pretty tight margins. So there isn't so much room for construction innovation. Nigel Waller and Rob Pebbles, Jo Richards reputedly built a basic Punkarella N12 hull in one night after the pub, by folding ply. Having designed it in the pub by folding beer mats. But again this is a box rule class. You can build boats simply in lots of ways. It gets challenging when the boat has to be a certain shape and simply built. *spellings
