4 hr Kayak
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.Wear a life jacket at all time.
