Materials & Production Process

- Carbon/Epoxy/Foam with different densities

- high precision CNC milled moulds

- vakuum infusion process, tempered in an oven
- high density foam in the areas of fittings (no wood or aluminium, no corrosion)

Hull design

The complete boat is designed in 3D and CAD software. The hull is carefully reproduced based on the 3D data provided by the International Flying Dutchman Class Organization (IFDCFO). We optimized the hull in between the rules.

- Maximum girth/volume in the bow
- Maximum width in the transom. 
- Minimum rocker in the transom section
- Minimum width/girth in the mid section

- extreme weight concentration in the center of movement (traveller)

To avoid mistakes we have added all measurement rules and illustrations in our plans and visualized the tolerances:

Flying Dutchman measurement informations

The red areas port side in the cockpit (top view) in the illustration above show the 50mm (!) thick high density foam. So you are free to mount fittings in this sections without any problems - just drill and screw.

Cockpit design

- Optimized cockpit ergonomics 
- Open transom, only 10cm deck/bridge at the transom 
  a) minimum wind resistance
  b) water is out faster
  c) you can see through the transom - so you can see if you're sitting too far back
  d) It's easy to get the rudder mounted
- Less buoyancy in the transom means much better behaviour when capsized:
  a) turns to 180 degerees much slower
  b) you get on your centreboard better
- Best maintenance, easy access on all the lines
- Long rubbercords up to the transom, so the cords last longer
- Easy mounting of individual fittings: big areas of high density foam in the center of gravity


- The structure of longitudinal stringers and frames absorbs all forces. The hull is only a shell.
- The second longitudinal stringers (yellow) are high to stiffen the boat
- Exact CNC cutting of all parts
- Carbon biaxial fabric with additional unidirectional layers
- 20mm foam without water absorption
- The structure is glued in:
  secondary bonding with a hollow joint and 45 degree biaxial carbon tapes
- The centreboard case is optimally stiffened in the area of the axle with extra bulkhead


- The foreship is extremely stiff - bulkhead made of unidirectionally reinforced carbon
- The longitudinal stringers run out in the front smoothly 
   (support where the ship hits the waves hardest)
- The forestay and genoa reel are attached to a carbon crossbar (10 years well proven)
- The spinnaker trumpet is max. large in the front, the spi goes in and out easily 

  (Carbon with Teflon-coated surface)
- No corners/edges where the spinnaker can get caught
- The spinnaker tube is made of kevlar - no fractures/leaking
- Forestay & jib furler line run through the spinnaker tube - further weight saving
- Small hole in the bow for a bow line / tow line


Double bottom

- The double bottom is extremely rigid/stiff due to the framework
- The double bottom is as deep as possible at the transom 
  a) offers the helmsman a better hanging position
  b) the water flows off faster due to the stronger inclination
- The double bottom is raised below the side decks
- The water under the side deck runs off more quickly, especially when heeling 



- The transom is maximally open and reduces wind resistance 

  (upwind wind resistance is more than 50% of total resistance)

- It's much better when capsizing, it doesn't capsize so quickly, water is out faster, you can get onto the centreboard better.
- it's easier to get to all the ropes. The rubbers can be longer, and therefore last longer.
- The rudder fittings are optimally accessible and it's easier to get to the rudder.
- You can see through the transom the water flow, so you recognize if you are sitting too far back when there is little wind.
- The center stringer supports the upper rudder fitting



 - The classic "one piece" rudder is extremely strong and reliable 

- Profile optimized by VPP/CFD technology 

- Produced in heated alloy moulds with 120t press 

- Carbon tiller and carbon tiller extension 

- New developed heavy duty rudder fittings 

- the rudder blade starts less than 1mm behind the hull -> less ventilation

Gybing Centreboard 

- Self-adjustring angle of attack, 1,6 degrees to each side
- Extremely high carbon ratio: 80% unidirectional carbon, 20% biaxial carbon
- Critical area head/outside hull massive unidirectional carbon layers 30 degrees angle
- Strong high density core (no wood)
- Profile optimized by VPP/CFD technology
- Produced in heated alloy moulds with 120t press


Centreboard case

- inside epoxy-graphite coating - the centreboard axis can be moved under pressure
- reinforced with extra strong biaxial carbon layers 
- The centreboard case is self draining due to it´s shape
