FAQ
Sponson
- What is "sponson"?
- Sponsons are the air tubes in the kayak skin. They are made from urethane and the seams are RF welded. Urethane is an extremely tough, yet light material. The sponsons slide through a chamber sewn to the inside of each kayak. Sponsons provide stability, and also tension to the skin.
Pre-caution: If the kayak is not being paddled, but is in the sun during the heat of the day, release some of the air from the sponsons. Air in the sponsons will expand and could potentially rupture the sponson.
- How do I repair/replace a sponson?
- If you need to patch a sponson, Aquaseal, a urethane adhesive, is provided in the repair kit. To shorten the cure/dry time of the Aquaseal, use the accelerant, Cotol. Follow the mixing instructions on the package. The Aquaseal adhesive is very slippery. Apply weight to the area being patched, ie: bag of sand, rock, to hold the area while curing. The sponson can be completely removed from the sponson chamber. Turn the skin inside out. The sponson chamber is open at either end. There is a tab at the end of the sponson with a hole punched through the tab. Attach a long piece of string or rope to the end of the sponson. Remove one side of the sponson by pulling it through the center opening of the chamber, where you access the sponson hose, pulling your rope through the chamber. Repeat with the other side. When it is time to replace the sponson, pull the sponson back through the chamber with your rope. Be sure the sponson lies flat and does not get twisted. Re-tie the ends of the sponson to the chamber with a piece of string or rope. This will limit the chances of the sponson shifting within the chamber.
