There is nothing about boating that is cheap (except the quality). If Chap has it get it, because it will be the original, you will spend more time and money looking for a used one and it may not be as nice as yours. If you can find out who made it for Chap, you might be able to buy it direct. Another way is to buy just the cover and if you are handy and have the recourses recreate the rest of the cushion yourself. Have you checked with Cecil Marine? or any other Chap dealer, or Chap themselves? If you have it custom made at a canvas shop, your main concern will be to have the correct color. Please keep us posted.
