Lost in the bilges......

[oscarvan]

Another day of discovery in the far corners of our Hatt. Do have the manual, in fact the one that came with the boat originally, AND a generic one.

So found two water tanks with gauges and two fuel tanks with gauges. Also two waste tanks, with a remote system that has the green/yellow/red setup. No idea if the 3/4 lights at the individual flush buttons are still connected.

And I'm figuring out the bilges. Pump in forward bilge which terminates at the aft galley bulkhead.

Question: I can stick my head under the generator room floor and look way back there. There is a white +/- 2" hose that comes down there...goes up the port side.... Unable to find it above the floor... Any ideas?

Found two bilge pumps inboard in the engine rooms. I understand the engines sit on their own bilges which will contain, up to a point and then spill into the side bilges.

Book mentions a fourth aft bilge pump, which I assume would be in the aft bilge. Hard to see on the "3D" drawing in the book. Where the heck is it? Last thing going aft in the hallway is a hatch with the top of the aft end of the forward fuel tank with a gauge. Other side of the door is a small hole big enough to see the gauge on the forward end of the aft fuel tank. Then the only thing aft of that is a small wooden "box" which lifts up in the closet in master stateroom with the "T" a shutoff for the port water tank and the check valve in the line to the pump....

No bilge...and, the hull is flat there.....

Also, the engine room pumps discharge through a rather thin hose to what I believe is referred to as a sea chest, one in each engine room on the hull. Port side is next to the A/C cooling pump discharge which is just above the water line, and then finding this outside the exit on the sea chest appears to be at the bottom also just above the water line. There is no loop, let alone an anti siphon valve in the hose coming out of the bilge pump. What keeps the water from coming IN this way.... I've seen bilge pumps barf up everything that was in the hose above them on deep bilge sail boats so I know it won't stop incoming water......

Also, what are the other two hoses on said sea chest? Heavy black, guessing 1"

Is there a picture or drawing anywhere that shows the hull before the floor goes in? Ribs and wells and bilges. That would be handy....

Thanks, as always.

Do you have a queen hour master stateroom or two twins? The aft bilge pump is in the center of the floor just forward of the shower sump.

Have you pulled the hatch in the v-berth to see if the white hose under the generator is the hose that feeds into the holding tank in the V berth. The center head empties into that holding tank.

The hose ends, open, into the forward bilge and comes down somewhere near the bulkhead between the galley and port engine room.

MEANWHILE.... I've stumbled across the diagram with all the waste plumbing. There's five sea chests and it lists everything that goes in to them.

Still wondering how you can have a bilge pump below the sea chest which is at water level with a non looped hose.... A good roll/wave and the sea chest is a foot or more below water level......

Chuck from Chartmaker has hull number 524. He has owned his 1978 for mor than 5 years and has been in every nook and cranny of his boat. He has been a great resource for me here in the Bay Area. Next time I speak with him I will let him know you’re the new owner of his sister ship. He did post a question on one of your resent questions regarding transformers. Look him up. Great guy.

Sorry hull number 522 on Chartmaker.

Sorry hull number 522 on Chartmaker.

Cool thanks.

Again mine is much earlier but this may help

Forward bilge pump hose comes thru the gen room bulkhead just under the floor, port side and into the sea chest behind the cabinets, forward galley port side. Almost impossible to reach

Addition hoses in ER sea chests are likely to be air handler condensate drain. Condensate drain for master AC goes to aft sea chests. STRONGLY suggest you clean these drains as they tend to clog up

Sea chests have a small hole at the very top to prevent siphoning.

Master bilge pump is just forward of the Transom water tank. Depending on bed arrangement there should be a small access panel under the bed

As Rusty (Seven) said, the aft bilge is in the master stateroom. If you have the queen bed, there is an access panel all the way aft under the mattress. Deep down in there you'll find both the aft bilge pump and the shower sump for the master and guest showers. I'm guessing if you have twins there will be an access panel between the beds on the floor. In the vee berth, there is an access panel in the floor that allows you to see the most forward part of the bilge. In there you'll find one of your holding tanks as well as two thru hulls. One intake with a strainer for the forward head and one discharge for said head if you are pumping overboard. I don't have a fixed bilge pump in there on a switch but a 110v sump pump I connect after extremely heavy rains. One of my next projects is to add an actual bilge pump in that area. Still working on where to route the discharge.

Thanks for the comments. Between those and the blue print I now have to look under the far aft end of the bed behind the tank......

Be there tomorrow..... it's fridge shredding day!
