Is it difficult to clean the hull cover when picking up?
You only need to clean the cloth enough that the worst of the build-up comes off. Because the canvas is made of soft material, barnacles and other vegetation easily fall off the hull canvas. All that is needed is a high pressure washer or scrub brush. If you want to be extra careful, you can use a little soap. Since the hull protection cloth will be back in the water next season, it does not need to be 100% clean.
