Don't be concerned by the vent hole in your Skimmer series kayak. The hole in the rivet behind the seat is included so our Skimmer sit-on-tops can breathe. You see, our Skimmers are designed to be as water tight as possible, but this means they tend to be air tight too, which can cause problems when they are exposed to extremes in temperature. While your Skimmer will probably never experience temperature extremes after purchase, our boats are occasionally exposed to intense temperature changes during shipping. In response, we take this extra step to assure that our kayaks arrive on the showroom floor as beautiful as the day they were born.
Once your Skimmer comes home, you can plug the vent hole to minimize potential water seepage, especially if you paddle in rough conditions from time to time. If you choose not to plug the hole, that's fine too, as the hole itself is rarely exposed to water. If you don't plug the vent hole and your Skimmer capsizes, water will slowly weep into the hole while the boat is upside down, but this shouldn't be an issue unless the boat stays upside down for an extended period of time. News Flash: All sit-on-top kayaks take on water during use (that's why they have drain plugs), but it's probably not a good idea to play capsize with your Skimmer unless you plug that hole first.
If you decide to plug the vent hole, we recommend using Gorilla Glue to fill the void. You can also plug the hole with a waterproof silicone, but the silicone might eventually need replacement.
Enjoy your Skimmer and don't hesitate to contact us if you have any questions.
