Yes, certain waterways can promote more growth. Waterways with fast moving current provide more nutrients to barnacles while areas with more exposure to the sun lead to more algae growth on waterline! If you move your boat to a new Marina you may notice changes on how long it takes the growth to appear! The picture below shows a boat hull in a high current and warm water Marina, this is 2 months after fresh bottom paint.
Prop speed makes metal surfaces slick lick like a sea snails shell. Prop speed is recommended to be applied on all metals underwater as it is self cleaning which will save you money on monthly cleaning costs! The photo below shows the differences in effectiveness with the prop having prop speed and the rudder having conventional bottom paint.
With the aggressive marine enviroment of Florida it is recommended that smaller boats (up to 82 ft.) use Interlux Micron 66 and larger boats (over 82 ft.) use Interlux Micron 99. Both of these Co-polymer based paints with Biolux SPC help keep algae and hard growth off your boats hull and waterline. Which will save on cleaning costs.
