When I built a bridge over a span of Ocean, I had to build 8m above the calm surface to keep storm waves from going over the walkway. 6m was too short.

thnx i believe after experiments that zero waves is (on this map) Y=30 so perhaps using Y=40 should be above waves (but i need water in a well so need to be below 30 also :-) )
