Reliable air conditioning, fridge operation, and water maker output depend on a clean flow of salt water. Trapping air in the plumbing, which leads to loss of flow, is a common problem due to suboptimal layout. This is the way it should be done.
The “T” on top of the through hull valve will have a standpipe attached that is plugged at the top. This will be used to clean the inside of the pipe and valve when they become clogged. The Hayward strainer is oversized to allow longer operation in foul environments.
Note the upward slope of the manifold and plumbing to the pumps. This allows air to clear itself. There will be a vent line at the end (high spot) of the manifold to aid in clearing as well.
Raw water feed to the engines has the valve above the waterline. This will allow the valve to be removed for maintenance without hauling out. Each engine and the genset have their own standpipe and strainer.
Looking at the port forward engine room corner. The day tank sump is centered and the balance of the day tank is above the photo. The opening in the bulkhead provides access under the shower seat for building and future maintenance.
Lazarette bilge pump is mounted in the engine room for easier access and to keep the aft bilge clear for storage.
The fuel and heater manifolds are located in the midships plumbing systems closet, along with the damage control pump and its selection manifold are shown above.
There are also a pair of bilge pumps that will be used for tank margins (mainly condensation in cold water), the stabilizer coffer dams, and the depressed tank top area amidships.
The PVC manifold above is for grey and bilge water, the galley sunk, and the previously mentioned bilge pumps. The galley sink has the option of direct discharge as well.
Finally, an early look at what will become the best cruising workshop ever and one of our favorite things on the FPB 78. There is that substantial work bench, a storage shelf under it, a huge toolbox (hidden below the box to the right), and loads of wall space for racks and photos. There is also a large area below the sole and aft for lubricants, filters, spare parts, etc. The workbench will have a vice, drill press, bearing press, grinder, and disc sander. And of course, there will be room for a large screen TV tied into the vessel monitoring and navigation system. There is also an air conditioner.
