Although it is unlikely that your Dagger kayak will need repair during its lifetime, it is possible that a hull crack or puncture might occur due to extreme impact or contact with a sharp object. If this happens, first contact Dagger or your Dagger dealer to determine if the damage falls under the boat's warranty. We will need the serial number of your kayak (located on the stern), a good description of the damage (a photograph is very helpful), and a description of the incident during which the damage occurred. All this information will help us to determine the best course of action in getting you back on the water. As an owner of a boat made from polyethylene plastic, one repair option which may be available to you is welding. Polyethylene is recyclable and repairable, unlike many other plastics. Incidents necessitating welding happen to less than one percent of Dagger boats, but if for some reason you should get a crack or hole in your boat, refer to the following repair instructions or call us for additional assistance.
