It Must be Spring
We had been visiting the boat about every six weeks to charge batteries. But since we expect to put Prana in the water in the next two to three weeks, we have begun the flurry of activities to ready her for launch. Today we applied a coating on the propeller called PropSpeed. It prevents marine growth from bonding to metal surfaces below the waterline. Propspeed works because it is slick, not because it is toxic.
Application of Propspeed is a simple two step process beginning with a catalyzed etch primer followed by a silicone based top coat. It is an environmentally safe product and does not contain copper, tin or any other toxic substances which may cause environmental pollution.
We applied it to Platina's propeller and noted a slight increase in speed and energy efficiency, but most notably, no barnacles and other marine growth settled in on our prop. We'll see how it does for our Prana.
Here are photos before and after the application today!
