Three-part Searacer – Rune Eurenius
A very interesting 3-part Sea Racer from Rune Eurenius!
"Posting pictures from the maiden voyage of my Sea Racer. Paddling the Sea Racer gives me associations of driving a sports car. The transition from my Hunter was easy, despite the relative low initial stability. I am not able to comment on the speed performance as I am in a relatively poor physical shape at the moment.
The integral rudder presented earlier ( http://www.utsidan.se/albums/view.htm?ID=7763 ) works really good, even at low speed. A well constructed carbon fiber cockpit rim from Petrus Kajak fitted almost perfectly with one centimeter to spare at the widest point.
The build was relatively complicated due to the 3-piece construction. There was no other option for me as I have no suitable space for a conventional build (or storage for that matter)
The kayak was constructed in my 67 sq.yd. apartment during 10 months. It actually worked out very well. Problems with noise and dust was eliminated with a fantastic Festool RO125 multi mode sander, connected to my vacuum cleaner.
There are virtually no play in the joints and the kayak feels solid despite the 3-piece construction. The joints are held together with countersunk M8 bolts, treaded in corresponding dome nuts. These are molded into 1 1/2" plywood beams with West Systems epoxy. 5/8" holes was drilled through the hull to accommodate glass fiber reinforcements for the bolts. See photo.
