Lifeboats of the kind that are sent to sailors in distress, or lifeboats of the kind carried by large ships in the event of having to abandon ship? One compromise made by the 42-inch yacht is speed. As a general rule, speed is proportional to hull-length: the longer the boat, the faster it can go [1]. In the case of the lifeboats carried by ships, they need to be space-efficient enough to be carried, and have enough capacity to take passengers, and although it's very stable, I'm not sure the 42-inch yacht would be practical as an emergency lifeboat.
