Hi All,
Hope your week is going well.
I have an old Dufour 34 from 1975. It came with a Manual Bilge Pump which I replaced.
The Bilge pump runs from the bilge and is connected to the scupper which is at the Cockpit.
I think the reason was that in case the bilge is filthy it will not mar the outside of the boat.
I was thinking of adding two electric bilge pumps.
A small 360 and a large.
The small I don't care how many GPH it will push as it is just a clean up one that will sit lower.
The big pump is where I am not sure how big I need to go.
If you look at the diagram, I estimate I need to run the hose 6 feet up, 3 down, so that is 20%-30% loss X2.
If I decide to go to the Chart table, then I assume if the bilge is dirty it will mar the boat.
I also am worried in case the boat is heeling extensively due to weather then water can come in.
If I decide to go to the scupper like the manual pump, then I was told it is not coast guard compliant as they consider it like the cockpit and you can't send bilge to the cockpit to be drained.
If I decide to go all the way back to the stern, I have a pretty long run so would lose in friction the 30% there, also same mar the boat issue, but I estimate this would be the safest.
So 4000, 2000, 1500 or just skip the whole thing if the boat has sailed for 50 years without sinking then Manual is fine.
If you can explain your work, I'll be most grateful.
Thank you
Saar
