For boats that live in the water year round, typically you can expect to get 2-3 years out of a quality anti fouling paint, whether it is an abaltive or hard product. There are exceptions but nothing is going to last longer than that. Talking about actual paint
products now, not copper-loaded epoxies like Coppercoat etc.
The manufacturers do like to sell "multi-season" ablatives to those of you folks with short sailing seasons. I will not speak to their effectiveness in this regard, having no experience with boats that come out of the water for the winter. But it is true that ablatives can withstand prolonged periods out of the water while hard paints cannot.
