I’ve compared the new C2 with The Darkness C1 because that was the starting point for the design however, to get a proper C2 perspective, I should compare it with The darkness Duet C2.
So I laid them side by side and took some pictures and measurements.
The Duet conforms to a continuous arc from bow to stern, whereas the C2 has a long section of parallel width. The Duet was designed by a Naval Architect using CAD tools and fluid dynamic algorithms, The C2 was pretty much guessed at.
Key dimensions are:
Max width at the gunwales: Duet – 68 cms, C2 – 56 cms
Boat depth from hull to central thwart: Duet – 27 cms, C2 – 28 cms
Boat depth at rear of cockpit: Duet – 26 cms, C2 – 29 cms
Boat depth at front of cockpit: Duet – 34 cms, C2 – 29 cms
Seat height: Duet – 20 cms, C2 – 15 cms.
Weight: Duet – 21 kgs, C2 – 18 kgs.
The weight comparison is a bit of a red herring as the C2 has the additional seat adjustment rails but would benefit from some additional stiffness within the laminate, but 18 kgs would seem about right.
This particular Duet is not really representative either as it’s based on two layers of carbon, hence the additional stiffening across the hull. Without the now standard internal layer of Kevlar it is more vulnerable to damage. A more realistic weight with the Kevlar would be about 23 kgs. This boat also has some seat rails because as the demo boat, it needs to be more adjustable. Adjustments for the rear paddler is serviced by moving the footrest.
As both boats are ICF compliant, the only difference in the hulls is the cross section profile. The C2 is much slimmer but water resistance is usually measured by the wetted area. The Duet will support a heavier payload and is massively stable, but it would be interesting to measure the wetted area when paddled by two racing snakes.
The C2 cockpit has less open space but at 310 cms, it is still greater than the ICF 280 cm minimum spec. I’ve positioned the seats closer together to take advantage of the central buoyancy. As the boat tracks so well, it isn’t necessary to have the rear paddler way back towards the stern. Also, we don’t need to leave the central area available for camping kit and the like.
I’ve set the seat height for the C2 at 15 cms. This is 5 cms lower than the Duet because I’m expecting it to be less stable.
The front deck has lost the steep gradient and the ridge. This should make it more comfortable for portaging, but there may be more water coming across the deck in rough water.
Notice also the lack of a name, what on earth I am going to call it? Dual, Duo, Double, Dunno!
The C2 is closest to the camera and it shows that the Duet has less height in both the bow and stern areas. It will be interesting to observe the freeboard, and how much will be sticking out of the water (and likely to catch the wind). I’ll also test the curved bow.
Tomorrow I get to test it, and the day after a Duet crew has agreed to give it a go.
