Did You Know


barnaclesIf you look anywhere at or near the ocean you will find barnacles. They are clusters of hard, whitish, pyramid/cone shaped structures. Barnacles live on most unyielding surfaces that are underwater for some time. This can be on rocks, docks, boats etc. This is where barnacles live, sneaking out when water covers them so they can sieve food into their homes.  After selecting a spot to live, the barnacle locks itself to the surface with its own superglue and will now grow into an adult and build its robust and durable house. When the tide goes out the barnacle shuts house to conserve moisture. The more the barnacle eats, the more it grows, and the more stable the substrate the larger they will grow.

For this reason a boat that is stationary for long periods grows many more barnacles. Barnacles on your boat’s hull will slow it down and considerably add to your fuel bill because of the drag.

Be extremely cautious if using anti-fouling paints, as they are very poisonous chemicals plus they leach into the water and are toxic to many marine animals, and the use of tributyltin (TBT) has been banned for small boats under 25m in Australia.

Boat Hull Fouling

AntifoulingBiological fouling (bio-fouling) is the accumulation of all kinds of algae, water plants and micro-organisms on constantly wet surfaces.

This can occur almost anywhere water is present, but is a particular problem for marine vessels and can even damage the hull and propulsion systems. It can also cause extra friction for the boat, resulting in a loss in speed and an increase in fuel consumption.
