I have a 17' Sea Ranger, I think they are the same beam. I can measure my fenders and get a model # on my trailer when I get home later this week if it would help. It's an EZ-Loader single axle, but can't recall specific model off top of my head. My boat fits between the fenders but just barely. if I don't get it loaded straight there can be some rubbing. I don't think my bunks are set up optimally though. Still tinkering.
