Maintaining Your Balance


Maintenance Schedules

Other Service Items

Harken winches should be stripped, cleaned and re-lubricated at least once a year

Windlass’ should be stripped, cleaned and re-lubricated once a year

Anodes should be checked once a year and replaced if necessary

Raw water strainers will clog up at different rates depending where you are. It is advisable to check and clean them on a regular schedule, say once a month, or more regularly if necessary.

Check filters every 6 months and clean as necessary

Bottom paint is typically redone every 2-3 years. Have a diver clean the bottom regularly to stop any significant build-up of growth on the bottom. They will be able to tell you how well your bottom paint is holding up.

How often to replace batteries will depend a lot on what type of battery you have and how well you look after them. If you have AGM batteries and treat them well they could last for 6-8 years. Lithium ion batteries are more expensive but should last longer depending on how often you cycle them.

Running rigging should last you at least 3-5 years before you need to think about replacing them.

Carbon filters should be replaced every 6 months to maintain performance. The 5 micron filters should be replaced more regularly, but will depend on how often you run the water maker.

Follow the manual on servicing your water maker and how to check your water quality salinity.

Someone should go up the mast at least once a year to inspect the rig for any problems.

Zinc anodes should be changed annually. When changed there should be about half the anode remaining. If more than half the anode has corroded in a year, then you either need bigger anodes or may have a stray current issue.
