How big should your raw water strainer(s) be? We are not sure, but we have two of these enormous (and very costly) Hayward strainers on the FPB 83 Wind Horse, and they have served us well.

We have never seen more than a quarter of the baskets filled, even in debris filled waters after hundreds of hours of operation. The same pair of overcapacity strainers is being used aboard the FPB 64s.
