On the cover: This 28′ (8.5m) 2012-vintage Cutwater cruiser appears to have a split personality at the halfway point during application of a new Boat Blue high-gloss vinyl wrap finish by Wrap Boats of Vancouver, British Columbia. The original gray gelcoat, badly discolored from exposure to ultraviolet light, could no longer be renewed by polishing. The full hull wrap refinishing took a three-person crew 32 hours, including preparation and cleanup. Story on page 28.
