I can’t speak to the newer skeeters. But I fish a 2013 ZX20 and I LOVE the 20’ length. I’m sure the rough water ride in a 21’ is smoother but I love the way my 20’ handles at speed and when the trolling motor is down. I go as full send as my boat will allow for the weather conditions of the day and I’ve never speared a wave or met waves (in Texas) that my 20’ couldn’t handle. I’ve never for one second wanted a 21’ boat. I’m also a bigger guy and fish with 8 rods on the deck at all times. I also have more room than I could ever need for tackle in a 20’. It’s a personal preference thing though. It’s why I drive a Raptor and not an F-250…Speed and agility over size.
