Just scored a couple of used Craigslist BucksBags single man pontoon boats a couple days ago and just happen to have a couple spare boat seats laying around from my boat rebuild. They happen to be the same seats as on the pontoons and are brand new. I had also put swivels under them. I was thinking about leaving the swivels on. Was curious to know if anyone else has done this on one of these one man pontoon boats and how it affected rowing and if it worked and/or was a good idea? Thanks guys...Randy
