It all depends on how often you use your boat and under what conditions. It is also important to consider the water type – fresh or salty. After sailing in salt water, the boat needs to be treated every time, because after drying, salt deposits are forming at the bottom of the boat, corroding not only the protective layer, but also the body material itself. When sailing in freshwater, the protective layer lasts longer. Your boat can be polished once a month (with frequent trips) or once a season (if you sail less than 1 time per week). It is also worth polishing the boat when it is sent to long-term storage at season’s end.
