FLOATING BREAKWATER FOR SEAPLANES,
FLYING BOATS, AND FOR OTHER USES
Edward W. McVitty, New York, N. Y.
Application July 13, 1944, Serial No. 544,686
3 Claims. (Cl. IMF-43.5)
This invention relates to an apparatus for
providing a landing for seaplanes and the like.

The invention is intended for use in bodies of
water which at times are so rough as to make
opposite ?oat.
landings of seaplanes, ?ying boats and the like,
provided with a chain or rope and anchor, which,
when dropped to the sea or water bottom, will
anchor the ?oating breakwater in extended con
dition, retaining the individual ?oats in non-con
hazardous and unsafe.
The use of this inven
tion will reduce the roughness of such large
bodies of water in restricted areas, su?icient to
permit the safe landing of seaplanes, ?ying boats
and the like in such areas, without damage to the
planes, and facilitate the mooring thereof in
rough seas. Under certain conditions the reduc
tion of the roughness of the sea by the use of this
invention will permit the take-off of seaplanes
and ?ying boats without damage to them. The
invention has other and extended uses such as
creating substantially cahn water on an unproJ
tected shore for boats, during loading and un
loading, either from a dock or beach.
In the drawing, Fig. 1 represents a plan view 20

The ?exible’ connections 6, ‘l, 8 and 9 may be
made of metal cable, chain or rope, or other ?ex
ible material which has the capacity of readily
bending to permit the ?oats to have a consider
able degree of independent movement.
The entire breakwater is in the form of a
large web and when in anchored position is re
tained in a stretched condition by the four an
chors 18, the connection between the ?oating
members being taut. When the breakwater is in
anchored position, the pull of the anchor tends
to pull the peripheral supports 6—9 under water,

The ?oating breakwater of this invention is
composed of a multiplicity of ?oating members I, 30 its force will be successively reduced or damp

?oats I are arranged in spaced relation in a se

3 arranged in lengthwise direction and the two 35 at docks and for other use requiring substan
tially calm water in an area in which the sea

would normally be rough. By attaching the ?oat
to the ?exible lengthwise supports 6——'| and the
ing members to one another, a large degree of
crosswise supports 8-9. At the point of junction
independence of motion is permitted between the
of a lengthwise support and a crosswise support,
the ends thereof are connected by a suitable ring 40 successive rows‘ of ?oating units. The ?exible
connection between the ?oats is also a factor in
