Hi BABE and Peter, the triangles unfortunately appear on some ATI/AMD cards with certain driver combinations (including my own).
I've previously reported this problem but the developers were unable to fix the problem.
It mainly occurs when the ocean is close to the terrain,
so the only workaround I know of is to increase the Height slider value for the Ocean.
Next time I upgrade my graphics card, I'll pick an Nvidia card 
thanx Morton thats great to know , ill do that in future
