After looking at many wave photos on this page, I think wave behavior
in that location is different than I am used to. This place seems to
have a very long period between waves with nearly flat water between
them, weird.
Was probably a 10-14' swell day with 13-15 second period. You have to
remember the waves hitting here have a couple of thousand miles of open
ocean to build in.
Keep in mind these are not traditional breakers, rolling into a beach, but
swells coming through a narrow channel - not very shallow water, but still a
bar with suddenly shallower depths.

It appears the tide was coming in, so the boat was caught in one breaker -
rolled and dismasted - continued drifting under the bridge where the wash
of a second wave rolled it again, and then into the relatively calm water of
the bay.
