The idea is that, when the boat is heeled, a portion of the hose from the leeward scupper to the windward through hull will be above the water level and will keep water from siphoning back into the cockpit.
The PO of my 25 had rigged the scuppers to drain straight down. When heeled, the low side of the cockpit filled with water. After I commented to a friend about this, he explained about the crossed hoses. On my 38, the scuppers are high enough above water level that even with excessive heel in the 30 degree range, the scuppers stay above water level. The hoses are not crossed, but that isn’t a problem. So whether it is advisable to cross the hoses or not will depend on the height of your cockpit sole above the waterline, and on how you sail the boat.

I don't get the theory of crossing drains. Seems to me that a crossed drain will start to approach horizontal as the boat heels and work less well. So what's the logic behind crossed cockpit drains? sam :-) C&C 26 Liquorice Ghost Lake Alberta On 2015-03-15, at 11:38 AM, Brent Driedger via CnC-List <cnc-list@cnc-list.com <mailto:cnc-list@cnc-list.com> > wrote: C&C must have bought miles of that stuff.

Upon investigation, I found that there was a low spot in the criss-crossed drains. I am not sure whether they were originally installed with a low spot or they just sagged over the years. In any event, I removed the old hoses which were "type B fuel lines" reinforced with steel wire. (had to cut them off with recip saw) and installed sanitation type hoses double clamped with no low spots. So far, so good, they always allow the water to drain off, no ice.
