to this day i can recall the sight of an enormous yacht high perched on a green and yellow breaker , its bluish keel appearing on the verge of squashing tlns starboard float far below in the trough , and , high above in the skies , leaning over us , heads and arms armed with cameras ; and an elegant schooner sporting a steadying sail , a distinguished looking lady strolling alone on the poop deck , barely deigning to glance down at us , with the whole boat perched on its wave visible from keel to masthead .
