Do you have "Before and After" pictures to share?
We have a very nice deep size sink in our 2007 Phoenix Cruiser 2350. Like the adjacent stove top, the sink included a Corian cover, but unlike the stove, we never used the sink cover. We always left it home.
I got creative shaping a large cutting board that I bought from Bed Bath & Beyond. Since our sink is square (with rounded corners) the cutting board can be flipped into any orientation desired. It has been a valuable asset.
