Boat Plans At Mystic Seaport

The fuel delivery system is how Im going to supply my main engine, generator and any other diesel fired device that might end up on the boat. This system is separate from the transfer system and is fed from one 200 gallon tank.
The delivery system is fairly simple although having quite a few valves. Basically, Im pulling fuel out of the 200 gallon day tank, through another Racor filter followed by a five port distribution manifold that directs fuel to either the main engine, generator or another device.
In case I have a problem with the Racor filter while under way, I installed a couple of " Ts " in line along with three valves, so I could quickly by pass the Racor filter without shutting down the main engine. I could then change the filter or do whatever was needed while leaving the main engine running. Once the problem with the filter was resolved, I then would bring the Racor back on line by moving the valves back into the filter mode.
Between the Racor and the distribution manifold, I added two more " Ts ", and three more valves so I could add a 12 volt pump to prime the main engine or generator. Both the main engine and generator have a manual primer pumps on them, but I wanted an in line electric pump to make priming the engines a quick process. If for some reason any engine looses its prime,
all I have to do is close one valve, open two valves, turn on the electric pump, and crack the fuel intake line on the injection pump. Im just guessing now, but Id say I could prime either engine and have them back running in less than a minute with this set up. For me, this is an inexpensive set up that is easy to do while Im running pipe that could pay me huge dividends some time down the road.Because Im using a manifold to feed multiple engines, I felt as if I should install check valves where the engine supply lines connect to the manifold. Im afraid that one engine could want to pull fuel from another engine, and start messing with robbing an engine of primed fuel, or causing air and headaches to enter the system.
Im waiting on the check valves to show up and Im looking into different fuel pumps for my electric lift pump I want to install. I left myself plenty of room to fit the lift pump between the valves and "Ts", but Im stopped on this system until my parts show up early in the week. Besides having shut off valves at the manifold, I need shut off valves right next to the main engine and generator. While it may seem like Im have too many valves on this system, I think that they will pay off big once I start having to service the engines and system.
Because of where I want to install the electric lift pump and and the type of pump I want, I held the 1/2" steel fuel line 1.25 inches off of the fuel tank. An added bonus of doing this is that I now have a nice grab rail running the starboard length of the engine room.

uare footage on the floor since Ive raised the floor profile and allowed the plywood to "slide" more outboard against the frames. Its amazing how much more room I have since the sole grew outboard when I mocked up the sole framing system. Screwing the plywood directly to the steel in my opinion will make lifting pieces of the floor a real pain in the ass years down the road as screws rust and break. Ill end up with about 6 2" of headroom once the finished ceiling is installed. This 6 2" seems to be my minimum as some areas will be a little more ( 6 7" in some areas). Im 5 11" tall and Im totally happy with the headroom I"ll end up with.
he screw getting loose on the lumber, and a squeak developing. It if for all the reasons I just listed that I think the adhesive will give me some a little better job.
ing without having to remove any partitions. For this reason Ill have to frame the cabin sole in a way that allows the sole to be supported from below while the partitions remain in place. I also have to frame in all my access panels in the floor for access to water tank valves and whatever else I need to maintain below the floor. In a nut shell the cabin sole is basically made up of lots of small pieces that fit together to make the sole system.
various cabin partitions and cabin components. Once I new where most everything will go regarding living space, I will put layout lines down on the sole and alter the sole to accept the framing above. Doing it this way allows me days to ponder locations and do mock ups to see how things fit. Now is the time I start fighting for every square inch so I want to make sure it works for me and works for the boat. Most of the decisions Im making have me giving most of my consideration to how easy things will be to service and maintain.


should give me a long life of reliable service. If for some reason the pump or motor fails me, I have a manual pump plumbed into the system that will handle our fuel transfer needs. I got the idea of the manual pump from a careful builder doing a fine job on building their 55 footer. You can check out Peter and his families boat building blog here: building koloa . If the manual transfer pump fails me I can use one of the four drain valves and another type of manual pump to move fuel. If I dont feel like doing that, I can block the vents and carefully use my air compressor
and a regulator to push fuel from tank to tank using the transfer manifolds.
ifold since I did not know from which end I was going to be feeding the m
anifold. I have the sixth port plugged. All the flexible fuel line Ive been using in the engine room is Coast Guard approved marine fuel hose.

op and pumped 30 or so gallons of fuel into tank #4 . I temporarily wired a plug end on to the fuel pump transfer switch and once I made sure I had the correct valves open ( I need to label the tanks), I turned the pump on. It took a about a m
inute for the pump to pick up the fuel, but once the the fuel hit the flow meter the sound of the pump changed and the flow meter started clicking off tenths of gallons. It felt good to finally have a system up and running.

ne 200 gallon tank that I will use as a day tank. The day tank will supply the main engine and generator with fuel. On the aft deck of the boat Ill have two fill locations, one fill for the starboard tanks, and one fill for the port side tanks. Both the port side and starboard side fuel fill pipes have ball valves in line to direct fuel to either the forward or aft fuel tank on each side of the boat. When I want to fill the forward port tank, I close aft ball valve and open the forward valve. Likewise, when I want to fill the aft port tank, I close the forward ball valve, an
d open the aft valve. When the tanks are full, all the ball valves on all the fill lines are closed. The fill pipes are steel pipe, 2" sch. 40.



y to complete all the water lines for the boat. Instead of using "Ts " hidden behind walls, I ran lines for every fixture back to the lazarette. I used a PEX manifold that comes with a nice re usable compression connector that has a shut off valve for each line. I still have to install the lines for the clothes washing machine, the salon 1/2 bath, and the aft deck outdoor shower, but I will have to wait to do that when the boat gets to the launch site. The nice thing about this manifold is that it is easy to expand and will be a breeze to winterize all the fresh water piping from this manifold by some simple valve turning and my air compressor. This was the smallest manifold my plumbing supply house sold with 9 hots and 12 cold ports. The 1" cold inlet goes all the way through so I can feed it from either the top or bottom.
hull in the engine room between station 9 @ 14. I am using the term station as this is how the prints describe frame locations, and these two locations are actually steel bulkheads. I framed the tanks using 1/4" plate. All the tanks have a baffle located @ 30" on center witch is also what the frame spacing is. The baffles have the corners clipped off of them and also have 2" holes in the center to let fuel flow freely between them. The baffles are welded on all four sides of the tank walls and by using the slug welding method I was able to weld the baffle to the tank top. All four tanks have a drain valve at the lowest point in the tank in case I ever have to empty the tanks completely.
e four tanks without providing a way to get back inside of them if I ever have to. I added an inspection port between each baffle for future maintenance. The inspection covers are made of 3/8 plate and are attached to the tank by a 3/8 stud that is welded to the inside of the tank wall. The inspection ports are 12" in diameter and are in the front wall of the tank. Because of the size of the tanks, putting the inspection ports on the top of the tanks made no sense as it would serve little use due to the depth of the tank. Getting the inspection covers to pass the air test proved to be the most difficult part of building these tanks. Using fuel rated gasket material I cut a gasket for each cover and punched holes for the studs. I then used a fuel rated gasket sealant applied to the gasket to improve the seal of the gasket. Because I did not want to stretch my mounting studs I used a torque wrench to tighten the nuts to the correct torque for a 3/8 bolt. My first air test showed each stud to leak! Next I tried using a heavy thread sealant on the studs. My next air test showed the studs to leak! The problem was the weld holding the stud to the tank was not air tight and my 7 psi air test was leaking past this weld and then past the mounting nut. My solution to making the covers air tight was to mill a counter sink in each tank cover to accept an "O" ring for each stud. I milled the counter sink in the covers to a precise depth so that the washer under the nut would compress the fuel rated "O" ring and provide a seal once the nuts were torqued down. My next air test proved all the studs passed the 7 psi test. I spent another day or so finding pinhole leaks in the tanks and making weld repairs. The final air test was to have the tanks hold 7 psi for 24 hours.


. Since Im going to be doing the generator wet exhaust, I need to finalize the wiring in the lazzerette and finish sheathing that room. Once the lazzerete is sheathed, I can make the wet exhaust connections and check another item off the list. Im at the point now that I want to be able to scratch these jobs off of the list and not have to re visit them. This order of work is logical as I wont be able to start the steering system until the lazzerete is completed, and the bulky wet exhaust gear is installed.
