We have had the prop-protection discussion with the yard we use in our harbor and the conclusion has been this: in their experience the less-expensive spray on coatings are good for about a year at best. After that they offer no significant protection.

Prop Speed, which is very expensive for whatever reason, is longer lasting. But they said that if one hauls their boat every two years, in this climate it's not worth the cost.

The best thing in their opinion to minimize prop fouling is to use the boat. For boats that spend most of their time just sitting and are used only seasonally for relatively short periods, something like Prop Speed can help reduce the amount of growth up to a point.

We have elected to use nothing on the props and until this year we've not had a growth problem. This year a combination of less time using the boat, a longer time than normal between haulouts, and a very, growth-inducing summer combined to promote a fair amount of barnacle growth on the props and running gear.
