Buy a Skirtworks skirt and do it right- it won't cost you a dime more. Have then build it to your boats setback to get the best performance out of it. Example: I have a Jackson kayak that I sit six inches from the rear combing and most manufactors build their skirts to a 4" setback- hence I never had a skirt that sealed well. Called Skirtworks and had them build my skirt for me. Six years later still dry as a bone and looks brand new. Just buy the right tool for the job. Skirtworks builds all my skirts and they are impressive in the craftsmanship and I've seen them all.
I love to dance, but who needs the music- It throws me off.
