What are the difference between a RIDER and a SUNSPORT

[suprasam]

I have a 86 Sunsport, but I was looking at a couple of Riders in another post. They look exactly the same, does anyone know the difference? The layouts look very similar, motors are the same. Thanks

I have an 84 Rider.

From what I can tell, the Rider is just a little-bit shorter. You can tell in some of the pics, the the playpen looks to be about a foot shorter.

I can't remember over-all length of my boat (minus the swim platform) if think it's just over 19' maybe 20'.
