The Offshore Safety Regs OSR require the 2 pumps for category 1 races (and maybe others) as David described. On my boat the one that operates from the cockpit goes out the transom. The cabin pump goes through the cabinets in the head and out under the toerail. (It used to discharge through a seacock.) Very few boats have manual pumps as a back up but it is certainly a good idea. I do not think the insurance companies require them.
