lso, the deck height right after the cockpit is reduced, so that climbing in the kayak would be easier. The hull’s upper bilges now have much more flare, especially at the 2 ends, to help improving secondary stability, that also has Cp (prismatic coefficient) increased to about 0.52 ~ 0.53, a value usually seen on a faster cruising kayak, unlike the quite – low value of 0.5 on my previous Serene – 2. Transverse metacentric height – Kmt increased to 26 ~ 27 cm, which indicates satisfactory initial stability.
Thus, Serene – 3 is designed with a shift to (primary and secondary) stability concerns. Directional stability (reflected by the Cb – block coefficient value of 0.39) is ensured with an improved rudder system. The beam is slightly widen to 46 cm, and LOA stays at 17 feet. The 5.2m length is an important factor, cause it could entirely fit into a 4 meter truck, which could be easily hired to transport the boat if needed, otherwise at 18 feet, I would need a larger truck, which could be hard to find.
The hull features a deeper V – bottom, something similar to that of the Illorsuit. In all three Serene – 1, 2, 3 designs, I’ve always tried to combine deep V – hull with a narrow beam, something until now I’ve only partially succeeded. Various other improves would be incorporated into this boat. I would build different hatches with big silicone gaskets, to completely solve the water leaking problem (hopefully). Also, there would be 3 hatches along the kayak, to better utilized the storage volume inside.
