I am still testing Jeremy’s JKK Supernova, a racing sea kayak from New Zealand. I did a couple of 5-7 mile runs on the Horsetooth Reservoir in a winter scenery including pretty windy conditions. Paddling was much drier than it would in my Thunderbolt kayak. The Supernova feels much more comfortable with my bumfortable foam seat. However, for a better comfort, I would have to trim the seat hangers as I did in my Thunderbolt.
I shot a few pictures of the Supernova together with Thundebolt-X kayak designed by Doug Bushnell from West Side Boat Shop. Supernova appears to be a few inches shorter than Thunderbolt, but much wider, and has much higher volume. Thunderbolt cockpit is placed more forward than in Supernova. I am going to measure these kayaks by myself. Data listed by manufactures are not very accurate.
Next, I added Sisson Nucleus 100, a multisport kayak from New Zealand, to the picture for a reference. I like that Grahame Sisson is specifying the sizes of cockpit opening for his kayaks.
These three kayaks have very different cockpits:
– Sisson Nucleus: a very roomy cockpit with a small opening (shorter than Supernova), but quite wide, tiller bar steering
– Thunderbolt: a long open cockpit, tiller bar steering,
– JKK Supernova: a roomy cockpit, but a very narrow opening, sea kayak fit, pedal steering
