Windlasses are not designed to hold high loads while a boat is
at anchor. When the windlass is not in use and the boat is at
anchor, the chain should be secured using a chain stopper or the
rope rode should be attached to a load-bearing point such as a
cleat. Lewmar has created a beautiful new range of cast
stainless chain stoppers made from 316 stainless steel, perfect
for sleep-filled nights and lazy lunches. Notes:
The 8, 10, 12, 14 and 16 mm chain stoppers have a Safe Working Load (SWL) that is greater than the SWL of the chain.
