You know, the OP could let his SO unpick the blue Sunbrella, which can then be recycled. If one is careful with the unpicking, it can be left as one piece, which would then be usable by someone who would be happy to have it. Sunbrella is expensive, and the blue lasts extremely well used as covers for
cushions in the
cockpit or as
sail cover type protection.
His decision will depend on what kind of yachties they want to show themselves to be. Some take pride in their frugality; others, not so much.
