serene – 3, part 17

ext came the rudder box, an interesting idea that I’ve come up with lately. First, when not in use, the rudder would be retracted completely inside the rudder box (and so inside the hull), it would be safer, tidier when transporting, moving the boat around. Second, and more importantly, the rudder box allows mounting the rudder in a lower position, which enables a smaller rudder blade. From the design phase, when drawing a hull with lots of overall rocker (the keel line has quite some curvature)…

I saw that bottom of the stern would barely touch water when the kayak is at full load, hence, it’s good to mount the rudder lower down, about 10 cm lower compare to my previous boat. So I would just reuse my previous rudder with more steering effect. Lessons learnt from Serene – 2 showed me that I need a more responsive rudder, so everything, from the rudder post to the control pedals must be redesigned, shorter “rotating arms” for the rudder, and smaller “moving distances” for the pedals.

For this Serene – 3, I would make the seat position fixed, so the rudder pedals must be adjustable, back and forth about 12 ~ 15 cm. Of course there would be only one paddler for this boat, that’s me, but an adjustable rudder pedals is desirable anyhow, though it’s not very frequently needed. I choose a pedal layout that would let me stretch and relax my legs and feet. Not a surfing boat, rudder is for some slight course adjustment only, I don’t have to rest my feet on the pedals most of the time.
