This depends on many factors, the main two being bottom paint condition and boat location. Most boats are cleaned every 2-3 weeks in the summer, when the water is warm and there's more growth, and every 3-4 weeks in the winter.
We replace zincs at approximately 50% of their lifespan, and you get a zinc condition report after each cleaning.
Yes. Marinas we work in include Harbour Towne, Marina Bay, Bahia Mar, Yacht Haven, Palm Harbor and Loggerhead, and we come to private docks and lifts too.
Yes, and the inspection is free. Call or send the form to set one up.
It can if it is done wrong. Scraping too hard or at the wrong angle can gouge the paint or the gelcoat under it, and ablative paint is made to wear away slowly, so it needs a light hand. That is why every job starts with a look at the paint.
Fast in warm water. In one study, test panels were fully covered within about a month in spring and summer, with less growth in winter. That is why most boats here are cleaned every 2-3 weeks in summer and every 3-4 weeks in winter.
Two different metals in salt water act like a small battery, and the weaker metal corrodes. A zinc is bolted on to be that weaker metal, so it wears away instead of your prop, shaft or rudder. A painted zinc stops working.
Usually not. A diver can take most props off at the dock. Shaft, strut, cutlass bearing or seal work is still normally done at a haul-out.
Often, yes. A prop shop can straighten and rebalance many damaged props. We pull the prop in the water, it goes to F&J, the prop shop we use, and we put it back on when it is done.
The bottom paint and growth, the prop and shaft, the rudder and strut, zinc wear, and the through-hulls and intakes. It does not replace a marine surveyor's haul-out inspection, but it shows a buyer what is down there first. Ours is free.
