From a sheltered location on the east side of Vancouver Island (e.g. 49° 02' 16" N, 123° 44' 47" W), the water is frequenly as placid as a lake. Standing on the shore to take a sight, it is easy to estimate your height-of-eye, and hence dip.
However, on the west side of Vancouver Island (e.g. 49° 03' 47" N. 125° 44' 35" W), you can be standing on a beach with rollers coming in.
How best does one estimate his height-of-eye on a beach with rollers coming in? Do you assume that the soles of your shoes, if just barely wetted by the last wave to come in, are at the same height as the tops of the waves out to sea?
