Sigma 51
New racing mono for Zenoah 25.4cc gas engines. Gas Tuned Pipes

Sigma 51 1300mm long (51") 355mm wide (14") Very fast and stable circuit racing and FSRO mono V boat for Zenoah gas engines. Very low for stability but easy to build with a large engine compartment. This boat is designed for RACING and will run in 8 boat heats without difficulty when most other boats are a handful with stability problems in race chop. The prototype Sigma using a ZEN7 Zenoah tuned engine on its first tests was able to run 60 mph and go full speed through the corners. Link to video of first test.
The Sigma is much bigger than the Panther with a very large engine bay. This allows the fuel tank to be fitted between radio box and engine for better weight distribution for racing. The boat was designed for Naviga FSRO racing (offshore) and Mono heat racing but is an excellent sport boat being faster and far more stable than the usual Lazers and Deltaforce/ Seaducer type boats etc. The hull uses a 24 degree deadrise with long rails and full length small chine rails and no hooking or rocker which give the boat amazing speed and cornering stability. Aerodynamically it is very efficient with a very low CG for stability. The prototype did not need trim tabs but we have included them in the kits.

FIRST INTERNATIONAL race. In Duisburg Germany we raced the Sigma with ZEN7 against the FSRO International experts in 8 minute heats. The Sigma made 34 laps in 8 minutes compared to the nearest which was 29 laps in 8 minutes and this was racing against cats and other monos. (This was in spite of running out of fuel and being unable to complete the last lap!)

Do not confuse these boats with normal fibreglass boats. These are top quality lightweight epoxy mouldings made with up to 5 layers of glass or 4 layers of glass one of carbon and kevlar and slow setting epoxy resin which means no distortion, no gel coat cracks and they are VERY strong. These boats are hand laid up in the ceramic mould. The mould and moulding are vacuum bagged and left in an oven for 16 hours at 50C and then postcured at 25C for 24 hours after removal from the mould. They are then joined with kevlar or Glass and again cured overnight in the oven. This makes for an incredibly strong, stiff and lightweight racing boat. Carbon kevlar is incredibly difficult to damage.	.
