I am well aware of this Tom, *my personal experience is we on Lake
Ontario occasionally get nice long rollers,, just as the ocean will
occasionally dish up some nasty square waves, (particularly common if
there is a large current involved, a la Gulf Stream). But more often
than not we get those nasty short waves, and most ocean sailors, more
often than not, get longer rolling waves.

Sorry if I sounded pedantic, Marty. I didn't mean to preach. The
oceans are a big place and weather is local and I haven't seen even a
tiny bit of what there is to see. Still, I quibble a bit with the
idea that the oceans will only __occasionally__ dish up nasty square
waves. If the waves are new (ie. you're close to a compact wx system)
or running against current they can get nasty and that, IM (limited)
E, is a common enough thing. YMMV.
