Wakemakers coming through with some welcome innovation for extra ballast in our boats

[HS]

How are you guys with the 750's on top of stop tanks stopping the "siphoning" effect? Are you putting the fill fitting towards the front? Are you putting valves on the vent hoses? Friend's 210 would start siphoning off the 400's unless you broke it.

I put a "loop" in the overflow / vent line by feeding the hose up under the gunwhale and back down to the thru-hull. Haven't noticed any loss while surfing. To prevent bag collapse and the vaccum issue on the hard tank I tied some twine between the sac fitting and the hatch hinge hardware to keep an open air route through the sac on the empty cycle. I also used the rearward most of the vent fitting (nearest the fill fitting) to keep the air route through the sac as short as possible.
