Their useful information goes as follows: 1.The hull in your photo was a pre release spy pic of the development plug (for those that don't know a plug is the part you develop to produce your production moulds). 2. The JB1 was designed, developed, and built by one of the world\u0092s leading freestylers Nick Barton in the powerful Australian Southern Ocean - serious surf not wind slop! 3. Given who designed the JB1 and where he rides it why would we copy the Richter, so let\u0092s look at why the JB1 so different. i) the bottom curve or rocker was developed and tested over the last 2 years in conjunction with a leading Victorian shaper and is designed to enable the rider to crank the tightest turns possible in both flat water and surf up to 4 metres - measured at the back of the wave! An integral part of the hull's rocker is the addition of bow, side sponsons which add an inverted side wall angle which is the secret behind the JB1's incredible stability and manoeuvrability. ii) the introduction of water into the pump has been designed to increase the flow rate and pump volume. This means the hull hooks up quicker and significantly reduces cavitation in aerated or white water. iii) the length of the transom has been shortened by 50mm compared to the Superjet and Richter which are identical which means the standard nozzle becomes more effective and the hull is more responsive when flipping and rolling. The overall length of the JB 1 is 2.0M while the richter is around 2.1M iv) the tray is 50mm wider than the Superjet all the way to the firewall; the Richter is stepped before the firewall v) the hood has an inner skirt all the way around the engine bay which makes it virtually impossible for the hood to be dislodged when landings don't go as planned. vi) the pole position is set slightly back from the nose in order to maximise the relationship between manoeuvrability and tricking. vii) the layup schedule, that is the types and qualities of materials that are used to produce the finished product have been developed in conjunction with FGI - Fibre Glass Internationals leading composite engineer to produce a hull that is both strong and meets Nicks target weight for surf style freestyle of 45kgs. The Richter is some 10kgs heavier at around 55kgs. Unlike the Richter we use a combination of the latest woven materials including double bias and bi-axle all of which have been proven to greatly increase the strength of composites which are used in extreme conditions. And finally we do agree that in some aspects the JB1 might look a little like a Richter. However given that both the JB1 and Richter and for that matter most other aftermarket hulls are based on Yamaha's Superjet it is little wonder that you can find similarities of appearance, but with the JB1 and Richter that is where the likeness ends.
