The anchor equipment consists of a 25 kg stainless steel bow anchor and a 65 m long stainless steel chain 8 mm thick.
The Maxwell anchor spill operates electrically and has an additional stopper for strain relief. A closed plastic canister inside the bow is used for storage of the chain, drained by hand through a hole in the top of the canister. The chain inlet at the anchor winch is sealed with a sealing compound for sanitary installation purchased at DIY stores. Its like modeling clay and can be used many times, besides, its cheap.
That way, only a little water gets into the chain box and thus into the boat.
