A galvanic anode is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion.
When a boat’s hull stays underwater, it can collect all kinds of algae, marine life, and barnacles over time. These organisms attach themselves to the bottom of the boat as a result. Once they grow on the hull, organisms will cause frictional resistance and much greater vessel weight. These effects strain the boat’s engine and cause it to consume more fuel. What’s more, drag due to dirty hulls give boats slower speeds and lower overall performance.
Boat owners mostly keep their hulls in tip-top shape for improved fuel economy. Research into the energy efficiency effects of ship hull cleaning shows that boats consume less fuel when they undergo regular hull cleaning. By maintaining good hull conditions, vessel owners can expect one to five percent less fuel consumption from their main engine. But these figures will depend on the following factors:
“It can be serene, relaxing and intensely challenging at the same time”
The one-day discover scuba program is a quick introduction to this underwater world. A short briefing covers the equipment to be used and underwater breathing. Tips to equalize the pressure in the ears and pool skills is followed by a training dive in the swimming pool to get acquainted with the scuba equipment underwater. Problems that can crop up underwater, like, water entering the mask, removing, replacing and continuing to breathe from the regulator underwater, are solved practically.
