Basically barnacles can grow in only a few short days. Barnacles need tidal flow. They also like it when the waters are warmer so spring and summer there will be more activity when it comes to barnacle growth. If you are at a marina there may be more growth on one section of the dock and less on another. This could be because of the way the water flows into the marina. They need food delivered to them.
Since all a barnacle wants to do is to take up space if there are more of them they will grow faster. Usually when I see a propeller fill up with barnacles in less than a week there are a lot of them.
On a boat the bottom paint will keep marine growth from growing. A good bottom job should last a few years (here in the Pacific NW) For trim tabs, rudder, shaft sometime a protective coating will work. However since the boat's propeller spins at such a fast rate it usually knocks off any coating leaving it exposed.
During more active months you may want to have your propeller cleaned before departing on a trip.
