feet north of the tip of the point and continued the line of the
east side of the point for about 750 scaled feet beyond the tip
of the point.
Figure 21 shows the deflector system deflecting floating dye
completely past the bathing area under southwest wind.
It appears from these studies and from the experiences of
others that a "floating fence" such as the Warne Inflatable Oil
Spillage Boom (which is now being handled in this country by
Surface Separator Systems Inc., 103 Mellor Avenue, Baltimore,
Maryland) would successfully protect the bathing area from weed
and flotsam. Brochures and descriptive materials on this "fence"
were loaned to Mr. R. M. Klenner.
Littoral Sand Transport
Figures 22,23, 24, 25, 26 and 27 show the distributions of
painted sand grains from plantings of sand on the inshore sand
bar just to the east of the channels of the proposed West Boat
Lagoon.
The great bulk of the marked sands moved diagonally offshore
and westward toward the extensive shoal area off Stella Mare and
the western edge of the Metropolitan Beach property.
There was some movement of sand through the cove at the
western edge of the Beach property. This movement was in water
depths of one to two feet. Very little painted sand was ever
found along the present beach of the cove.
The movement of littoral sand seems to be an expression of
the southeast winds, which have the greatest open-water distance
to blow over, and hence produce the strongest alongshore currents
