• Hull Cleaning •

When done correctly this service gives you better fuel efficiency, higher speeds, and a longer life for your boat. When performed incorrectly it can introduce high levels of copper and biocides, such as cuprous oxide, into the water.

A hull can be painted with either hard (low copper) paint, or anti-fouling paint (often referred to as an ablative paint). Hard Paint will be slicker, and will allow your boat to move faster through the water. However, it will require regular hull cleanings to remove the slime coat and keep it free of marine life such as barnacles. This type of paint has less tendency to come off during hull cleanings.

Anti-fouling or Ablative paints are designed to slough-off any marine life that would try to grow on your boat's hull. This type of paint is ideal if you keep your boat in the water for any period of time greater than a week. It does a great job of keeping your hull free of barnacles if you paint it regularly (normally on a two-year rotation). One drawback with most anti-fouling paints is that they have high levels of copper and biocides which get sloughed off along with the barnacles into the water. This is especially true when a boat hull, painted with an anti-fouling paint, is cleaned while in the water. These elements are harmful to the fragile marine environment. At V International ,we will use the least abrasive materials possible to clean boats with anti-fouling paints.

Why do you need zinc?


The simple answer is to stop the corrosion of metals. The reason why they corrode is a little more complex but critical to know if you own a boat. In some situations, zincs may deteriorate at a rapid rate and by understanding how they work, you can troubleshoot your own boat. 

First, to explain the chemistry, corrosion occurs anytime two or more dissimilar metals are placed together in a conductive solution (seawater). Corrosion is most severe on the least noble (most corrosive) metal.

Typically, boats have Bronze, Stainless Steel, and various other metals. By placing Zinc into the equation, we are adding a less noble metal that will corrode first but can be easily replaced. Using this more corrosive metal, we are protecting the more expensive components from corrosion. 
As zincs deteriorate, they build up a coating that renders them less effective. This is why it is recommended to replace zincs when they are half deteriorated. How frequently is dependent on how much you run your boat, how many zincs you have, how your boat is wired and how other boats in the marina are wired. It is always better to be safe than sorry. The cost of zincs and installation is cheap compared to the expense of your other hardware. If you are unsure of the condition of your zincs give us a call. It's probably cheaper than you think.
