Lol....saw that fish pic someone posted........Interesting. So that is what the "saltwater series" means is closed strakes/foils as well as extra zinc anodes? My 2017 22 SSRCX SPS has the stern ends totally open of mid length strakes on center full length toon, and the outer toons have a round hole in stern end of its longer strakes. Which are foils/ which are strakes and are there different length options or are all SPS packages the same length? I am confused now.....also old brain hurtsTo keep the catfish out!
But in all seriousness it depends on environment. Here in Florida they are sealed to keep the critters out and keep saltwater from getting caught in there.
