CORRECT MOORING
1) The mooring springs can't be immersed in sea water, for a long time, without an anode protection (sacrificial zinc) as well as, as a rule, those used on the propeller shafts.
In the absence of such compliance, SPRING WILL BE, in a short time, OBJECT OF SHAPES OF LOCALIZED CORROSION (see definition and list of types of "localized corrosion" on internet or on the retailer's indication)
2) Do not use chains for mooring which, immersed in sea water, can be excellent conductors of galvanic currents - stray currents, but suitable cordage.
In the absence of such compliance, SPRING WILL BE, in a short time, OBJECT OF SHAPES OF LOCALIZED CORROSION (see definition and list of types of "localized corrosion" on internet or on the retailer's indication)
3) For the correct assessment of suitable mooring spring purchase for your boat, you must report the weight of the boat to value of breaking load less than 30-40%.
4) At first use, lubricate the guides and the rods tie with spray grease for boating.
5) After 6 months check the wear of the guides and lubricate.
6) Check the locking of the tie rod nuts after 12 months.
7) Check the wear of the friction guide and replace if necessary and lubricate
