The CNC Kayaks “Shrike-R,” designed by Christopher and Nick Crowhurst and detailed on their website, here. This is a narrow, low-volume, high-performance kayak optimized for rolling. Recommended for paddlers between 140 – 190 lbs (63 – 85 kg).
The Shrike-R is an amazing rolling machine. Due to the low foredeck, wide cockpit and low back deck the kayak feels as if it finishes the rolls for you. She balance braces like a dream with enough stability to read a newspaper if you wanted to. Her ultra-lightweight hull provides little or no resistance to rotation, making rolls effortless.
It is offered either as a pre-cut plywood kit for home builders or can be custom built by CSCWC.
From the CNC Kayak web site:
The Shrike-R (AKA Shriker or Rotator) is a further development by Christopher from the Shrike Too design. It has two significant enhancements: a substantially lowered deck level (60mm lower than the original Shrike design) and a wider cockpit. Both changes enhance the ease of rolling. The wider cockpit enables the center of gravity of the paddler’s body to be lower during rolls and the lower deck facilitates layback recoveries. This kayak was developed specifically for rolling training and competition and is impractical as a tripping kayak due to its low deck level. With 190lb load it floats with 20mm of freeboard behind the paddler.
Due to the reduction in topside height, the length of the kayak is reduced from the original design. However, the underwater shape is identical and so the water line length remains the same, as does the rocker. This results in the kayak performing similarly to the original Shrike and Shrike Too, with the exception of the lower back deck making the kayak more affected by waves on the stern quarters, which tend to grab hold of the kayak due to the lower edge of the gunwale. This can make this a more challenging and lively kayak in big waters.
When Christopher constructed this version he did so without hatches or a skeg as this kayak is just for rolling training. Hatches and a skeg could be added if desired. However the extremely low back deck would make it a challenge to fit a large skeg so it would be necessary to scale down the skeg design in the plans.
Stitch & Glue Kit: Plywood Components
This is a basic CNC-cut kit. The hull panels, deck panels and coaming parts are professionally cut by Chesapeake Light Craft from 3mm BS 1088 okoume marine plywood. The forms are cut from particleboard or MDF. This kit includes only the plywood components. Any solid wood for the sheer clamp, masik and other deck beams, epoxy, fiberglass, hardware, footbraces, and so on are not included. We encourage you to purchase those from local sources.
The kit has been optimized for the home builder and saves much of the labor and stress involved in cutting out the panels. The design has been modified slightly: The deck is still adjustable for different heights but has been modified so it is easier to assemble. Precision puzzle joints aid scarfing the longer panels. The coaming is now built using stacked plywood rings for strength and a quick build.
The kit is packed in CLC’s standard kayak shipping carton. It’s pretty light so shipping is inexpensive. We’ll contact you with a shipping quote once you’ve placed your order, and you’ll approve the shipping before you’re charged for the kit.
The build manual is produced by CNC Kayaks. Modifications to the manual for the kit are by Clear Stream Custom Water Craft. The build manual and modifications will be sent to you electronically. They can be ordered for delivery at additional cost (the only cost is the cost of paper and shipping).
