serene – 3, part 1a

t’s time to move on to a new kayak design 🙂 . Lessons learnt from my last failed trip signifies the necessity for a boat design that is geared toward a wide range of self – rescue actions such as: balanced brace, roll and wet – entry. Thanks to the very dynamic world – wide sea – kayak community, which constantly invents and improves various techniques, I’ve updated myself to some newer self – rescue techniques which I consider to be critically important for long cruising trips.

My previous boat, Serene – 2 has some obvious shortcomings though: initial stability is still slightly problematic, the electricity system, though working very well, is hard to repair or upgrade, this is due to my inexperience with electrical wiring. I’ve incorporated into this design various small improves here and there: the storage compartments and hatches would be rearranged to better utilize the boat’s volume, a new rudder system with better responsiveness, etc…

For the last 2 months, most of my free times is directed toward working with FreeShip, the very helpful boat – designing software. Some design parameters: LOA: 5.2m (17′), Beam: 46 cm, Displacement: 120 kg, Cp (prismatic coefficient): 5.3, S (wetted surface): 1.95, Cb (block coefficient): 0.39, Cw (waterplane coefficient): 0.7… The most important change compared to Serene – 2 is a significant increase in rocker, the boat is now much curvy, having the mid section deeper seated in water.
