PART SEVEN: ANCHORING SYSTEMS
deep-water anchoring capability! Between
40 and 85 feet (12 and 26 m) of chain are usu-
ally installed on these rodes between the wire
and the anchor.
These reel-drum windlasses are decid-
edly industrial in appearance; however, they
could be installed on a yacht by building thewindlasses largely into an enclosed, though
fully opening, housing. This wire-rope system
is worth keeping in mind for the right
application.
Note that stainless 7× 19 wire rope of 316
alloy is weaker than 304, but only 316 has the
corrosion resistance required.TABLE 23-14. 7 X 19 316 STAINLESS WIRE ROPE
