yes 6inches - Valtero valves ; total overkill 3 or 4 is fine for most boats (If I understand correctly:
Big big transfer pipe, 150mm?
yesScoops feed into the centre section of the transfer pipe between gate valves.
correct,as it is not self primingPump suction comes from same section of tube.
correct pump lifts water via 2inch pipes into tanks, the 6'inch pipe is for dumping under gravity (Solent UK waters means there is need for lots of fast tacking hence the 6inch pipes)Pump pressure side goes straight to tanks, gate valve for each.
It looks like there is a third line out of the pump, is that a pump to sea? Or fill from the scoop. I would have
yes Marin is french company who manufacture Sofo scoops, we had 2 one port ; one stb and opened which ever one was on leeward, can rotate the inlet from 'scoop' to drain - so can lift/fill or dump via the scoop, they pull in/retarct when not in use. the were 2in scoopsthought scoop like would be better plumbed to the centre of the transfer pipe, so you can use the pump to lift the water to the tank of required?
I don't know what the marin industrie valve is in the second last shot. Is that the scoop valve?
Are the scoops a purchasable item, or a custom job?
a good basic set up is that used on the Figaro Mk1s - i used that on a Beneteau First class8 that i water ballasted for the 2H RB&I race in 1992Sorry for all of the questions, I'm about to start racing an 11m boat with 350l of water ballast a side, with a pretty basic setup. The more good ideas I can pinch here the less time I have to spend gluing PVC pipes inside a cramped hull
How often do you use the pump? I assume you always try to use gravity.lift pump was non self priming,
Can't you scoop in to the leward tank on a beat? How long does it take for the pump to fill the tank?pump to lift in, then its all gravity
Would you want to be drinking water that has been sloshing back and forth inside fibreglass and plastic tubes?Is anyone just using fresh water and a watermaker and their regular water tanks?
Just during the scoop and fill process, before the race starts.why would you want to put weight on the lee???
The OP was talking performance cruising, not racing.Is anyone just using fresh water and a watermaker and their regular water tanks? Then all you need is the transfer pipes and bigger vents.
Then you start the race with either one tank full from the dock or empty.
I appreciate that this isn't suitable for short tacking.
boat was sold to E coast USA someone on SA may know her whereabouts?
