Sandy Bay Harbor of Refuge Breakwater
Sandy Bay, Mass.
Construction and Rehabilitation History
1886-
Partially completed during this period were 6,100 ft of a planned
1916
9,000-ft-long cut stone and rubble-mound breakwater (Figure 21). The
breakwater's southern and western arms were 3,600 and 2,500 ft long,
respectively. A built, the breakwater consisted of a rubble-mound
s
where the width was 8 ft. Approximately
1
substructure built to
of superstructure was constructed at the junction of the
922
breakwater arms. The superstructure consisted of a rubble-mound core
and a cover layer of stone blocks stacked horizontally in an over-
lapping step-wise fashion to elevation of +22 ft mlw, a 20-ft top
width, and
side slopes. Additional armor stone, weighing a
of 1 tons, was placed on the seaward face to a
side
0
slope. Total costs were

1,500.
The breakwater has no repair history, and the uncompleted portion is
1986
inactive. Its original purpose, to provide a harbor of refuge, has
become obsolete due to the advent of powered vessels and their
ability to seek refuge at existing harbors.
