@Crazy Dave Condon How do you know for sure that the hitch was not changed by someone in the past 17 years, possible after a crash or modified for a tongue extension?2 inch ball. Former Catalina dealer who use to display the trailerable Catalina sailboats in Annapolis besides having a friend who designed that trailer for Catalina

Get all three. I've changed the hitch to 2 5/16 ball on several trailers so I didn't have to change balls.0 This could have been one of them.Just get both and see which one fits.
