Nice work Erez! Makes one wonder if a nesting 3 piece Kayak could be built. Great job on the squarish hatch covers and seals. Hope you have solved the water entry problems. I purchased the hatch kit from Pygmy for my Coho and both hatches suck down so tightly that I have problems opening them. No possibility of water entry. You mentioned a pump - did you install a footpump? If so how did you install it and the associated plumbing? Installing a skeg was wise! My Coho weathervanes even in the lightest breezes and it is almost uncontrollable when in beam seas and breeze. I am going to retrofit a skeg ASAP. How did you build the control end of the skeg cable? Kajak Sport has the best control for the skeg I have seen I will attempt to build one that is similar. Anyway, nice boat and nice website! Now, I hope you take a break from building and paddle, paddle, paddle!
