Why a combination wrench set with socket ends is ideal for tight engine spaces

Lauren Landers Sailing recommends a compact combination wrench set where one end is a standard open wrench and the other end has a ratcheting socket. The original motivation was impeller replacement work, where access is tight and a full socket set is awkward to maneuver. The combination design means you can apply more controlled torque in confined spaces without swapping between tools. She notes these wrenches ended up being useful across many engine tasks, not just the impeller, and she strongly prefers them for general engine bay work aboard her boat.
