Four-Hour Grip Clip Kayak!You can build a kayak of green willow shoots, a blue tarp in just four hours!
Some of the willow is twisted into ribs. Some into stringers. The largest two ribs are 16" by 27".The stringers are overlapped 2' 3" (this makes the stringers stronger in the middle where they need it the most.
You might also try nylon cable ties. Make sure if you do that you keep the tail of the tie long or if you cut it that you have the sharp cut end facing in away from the cover. You will also want to tighten it so that the gripper part of the tie is inward; since it it faces outward it could cause a hole to wear in your boats cover.
Completed frame. Length is 11.5'. Stringers are about 15' long and overlap the two center ribs. The center ribs are 27" wide and 16" deep. The next out from the center ribs are 19" by 14". The smallest ribs are 13" circles. Spacing of the ribs is 17", 17", 24", 24", 17", 17".
If the tarp is pinched between rocks and the boat's frame, it can be punctured. Two tarps layered or a nylon-reinforced tarp is stronger. However, since the blue tarp is easy to obtain and can be repaired with duct tape or with a patch of tarp material and silicon rubber as a glue, the blue tarp kayak makes a lot of sense for most conditions. Wear a life jacket at all time. Flotation devices such as inner tubes should be added inside both ends of the boat for additional safety. To make a stronger boat you can cover the frame with heavy coated nylon or vinyl. You can also make the frame of thicker wood. silicone rubber can be used to seal the gathering at the stern and bow by applying a generous amount between the layers before securing (this is not necessary unless you plan for the seam to be under water). This boat is intended for flat water use and not for use in white water. One reason for this is if the boat was crushed against a rock, the frame could collapse or brake pinning you in the boat and preventing you from swimming to safety and possibly drowning you. bob@shelter-systems.com.
