I would like a ride in one! 
River Pros are great fishing platforms (CA’s is huge inside) and they move. I wouldn’t recommend one for fishing Winnie/Leech ext…but for fishing thin water or water with a lot of bumps (wood/rocks) they are the cat’s meow (pardon the pun
) They are built like a tank…I’ve witnesses this the Catten Addict. We (in the darkness of night) boated over a root wad…and it was just like a tank…nose all the way up in the air until it was midpoint…then nose all the way down…exactly like a tank…after gathering my wits..checked the boat…and couldn’t find a scratch. It was amazing
Fish Head had a post in the Cat Forum a while ago that was good about jet boats and River Pro’s… He’s also a River Pro owner..
