Typically any swell that size while at sea isn't going to impact you much at all, the issue with the north swell is in an anchorage where the waves begin to "feel" the bottom. Mathematically, this happens at depths of about half the wavelength (the actual formula has a TAN function, but for rough approximations this number is about right). This is the depth where the waveform changes. Interesting -- got any good links for this? Thanks, Dan
