When the boat was lifted out for survey I was pleased to note that there was virtually no weed at all on the underside, but there was a fair degree of barnacle (?) type growths on the hull as can be seen in the following photos. Now my initial reaction was one of disappointment, but to be fair there are a number of factors still to be taken in consideration before I make final judgement on the effectiveness of this piece of kit.

(1) The boat is sitting in a deep harbour and not moving very much at the moment, therefore rendering the anti fouling on the hull a wee bit ineffective as there is no water regularly flowing over the hull. Remember also in the Med there is not much tidal flow compared to the UK!

(2) The underside wasn’t coated with fresh anti fouling when last lifted and cleaned in May 2013. Sun Dog was last antifouled in January 2012.

(3) Now I don’t know for sure if this next point is valid, but I have had issues with battery power, and cutting a long story short, I discovered on this trip that the domestic bank of batteries are no longer holding a charge, and therefore perhaps the Ultra Sonic kit has not been delivering its full effect, as it cuts out when the voltage drops to save draining the battery completely.
