Build a Cadet Dinghy

Build a cadet dinghy Continue Over the years, more than 10,000 cadets have been built. Notable builders and brands include the ass Jack Holt, Ron Beasley, Capel Sailing, Van Wettum, Rowsell and Morrison (RSM). Many of these boats were very well built and maintained and still sailing and even competing! An international cadet boat can only be built by a licensed builder. The International Association of Cadet Classes issues official licenses to selected quality boat builders around the world. Our goal, in promoting the cadet boat internationally, is to have licensed builders on all continents where the cadet sails.

With its widespread distribution in more than 35 countries and 5 continents, Cadet is truly an international racing boat. The boat provides a three sail experience where the steering wheel and crew must work together as a team to get the best results. The first cadet was designed by British boat builder Jack Holt in 1947 (as seen in this period photo in his Cadet 1.0). Originally designed for self-assembly, the boat soon became very popular and spread around the world. Over the years, the cadet has evolved from wooden MK I to modern MK IV, i.e. from glass fiber (GRP). Today it has all the trappings of a racing boat and even includes a spinnaker. In its more than 60-year history, the cadet has introduced more than 200,000 children with the joy of sailing, as well as several Olympic sailing medalists. In B The last European Championship more than 90 percent of the fleet was built by GRP. Cadet is a single boat design and therefore all cadets have the same, strictly controlled, measurements. While the material and appearance changed over time, the shape of the case remained the same. Today, wooden MK II and GRP MK IV compete in the same races, although most boats these days are built by GRP. The boat itself is 3.22 m long, weighs about 61 kg completely rigged and has a sail area of more than 5 square meters.

Published in 1964, this small book had photographs and details of various sailing boats and yachts. One photo showed two OK dinghies screaming along at Broad Reach in 1962 National on Hayling Island. This picture began a love affair with OK, which lasts to this day. Around 1974 I bought a set of plans from Bromley Boats with the aim of creating one for myself. Plans have remained in their envelope for years, surviving eight house moves, only ever seeing the light when sometimes taken out to study, but always put off again as other projects took precedence. I finally bought the 'Bluebottle' GRP 'OK' around 1980 and raced with some success (he speaks modestly) to TSC and other local clubs before selling it to help fund my 'Twister's' construction costs. Fast forward to 2015 and retirement and too much free time. I recently refurbished the Duffin GP14 but soon sold it as I don't like crews. An article in Yachts and Yachting about Dan Leach designed, and amateur built, wooden OK winning at world championships bought me back to thinking about OK building. Although a strict design, experts have squeezed tolerances over the years to produce faster enclosures. Dan Leach's design was tweaked to provide the best performance in any conditions and the boats were built inside a wooden jig that was precisely carved so that any boats built inside it must be OK. I've had some discussion with Dan Leach in New York. He wanted about 350 pounds for his computer program for cutting panels by the CNC router. There was also going to be a cutting charge in the UK for each of the 10 or so sheets of plywood needed to create a jig and a boat, which at the time I couldn't find anyone to do anywhere near the 12.50 pound sheet that Dan suggested. Being a poor retiree with no money and loads of time I thought: I can do it all myself. My estimate was about 700 sterling to build a case using plywood and epoxy resin. It would be closer to 1500 pounds if I I Dan Leach's itinerary. It was only for the hull and does not include fittings, masts, sails, etc. or labor. With growing confidence, I set about developing my jig. Paper cut outs showed how easy it can be and with growing confidence I put my money where my mouth was and splashed out on three sheets of 18mm plywood for jig and 4 sheets of 6mm marine plywood for the hull. With the CNC router cutting, you place a sheet of plywood on the frame and the router works around cutting panels according to the cutting program. I think they leave sheets like one with little tabs holding it together. It's a bit like a model kit. Depending on the complexity of the design it probably takes about 20 minutes per sheet and gives the perfect cut. So in an hour you would jig the cut. By doing this himself, the jig took about three weeks to cut. Accurate marking is important. The trance, three stations and the bow are clearly defined in the rules of the class. Although most sizes were tolerance plus or minus 10mm, I dare not try to be too smart with the shape, squeezing any of the sizes, so I planned on the mid-road boat. Accurate cutting was achieved using a pattern following the router bits and clamping or screwing the manual on the boards. With patience, it was nice how hard jig eventually as I was able to get a jig to lock nicely together. Sloting Jig together took a few minutes, and suddenly, out of a pile of plywood panels, I had what looked a bit like a boat. It was easy, I thought. The rest won't take long..... With my trips to the Baltics and other commitments, Jig was about as far away as I got in 2015, but I also bought an 'OK'1840 to play with, an old composite boat with tired decks but a nice sound hull. As a bonus, she came up with three above deck covers, one of which was virtually new and flawless. This lid was quickly stored in the attic while waiting for the new boat.

This is one design class originally designed by Jack Holt in 1947. Cadets swim around the world in more than 40 countries. History In 1947, Yachting World organized a design competition for a sailing boat for beginners, which was won by the current cadet The design of the boat is a crew of two people and sails with Bermuda rigged mainsail, jib and spinnaker. Cadet is the only one The two-person youth boat World Sailing (formerly ISAF) as an international competitive youth sailing class since 1958. More than 10,000 cadets have been built worldwide by registered licensed builders on four continents. Cadet sailed internationally throughout Europe, Asia, Australia and South America. Originally made of wood, much of the international fleet is now built of fiberglass. The strongest fleets are currently located in Ukraine, Poland, Belgium, Australia and Argentina. The Argentine sailors won 14 world championships in a 20-year period from 1991 to 2010. The cadet is 3.2 metres long, 1.38 metres wide and weighs 54 kilograms. With the central side up, the hull project is 16 cm; The mast is decky and 5.22 m high, the mainsail area is 3.9 m2, the jib is 1.26 m2 and the spinnaker is 4.25 m2. Side decks are designed so that rollover does not normally fill the hull with water.
