I have a 20 foot Redfin tunnel hull and have had it since new in 1992. It was and still is as far as I know the biggest boat that will fit in my garage. We have used it everywhere from Toledo Bend to Galveston North Jetty. It has held up well, still looking almost new, I'm sure garage stored and rinsed off after every saltwater trip have helped with condition. It's not a rough water boat, although it can handle it when the unexpected weather shows up.
I read a lot on this forum that they are very wet, and I really wonder how many of those people actually owned one or are repeating what they read, or took the time to learn how to drive it on a cross wind. In a cross wind, shift passengers to the downwind side and it is considerably dryer, knocking the spray down instead of cutting into it. Also add scuppers to the floor drain holes if it doesn't have any. The floating ball type work perfectly and keep the floor dry.
I speared a ship wave on the channel side of the North Jetty years ago with my wife, a friend, and my two boys in the boat, and it ran fine and drained quickly.
The front and rear decks are perfect for fishing chairs and a bow mount trolling motor.
I replaced the galvanized trailer a couple years ago with a tandem axle aluminum one and it looks like a new rig. Any time the carpet started to come up I glued it down and it too has held up well.
