angeljames613,
I've gone from a belly boat to a u-boat to a pontoon. Being high and dry out of the water is very welcomed with a pontoon. As well, having the option to row, kick or both simultaneously is a benefit, too (I'm not a great rower so I use my fins to keep me straight as well as add extra juice to propulsion.)
I have the ODC 945. As far as I can tell, the differences between the two are slight. The blue ODC 886 utilizes the push button valves and also has insulated cup holders. The green ODC 945 has Boston valves and no cup holders. The dimensions and capacities are the same. Even the accessories look to be the same.
I don't mind the Boston valves because I know I won't have to rely on an OEM adapter to inflate my pontoons. Bostons valves are pretty common and if I forget my pump at home, I know I could borrow a pump and get the pontoons filled. By the way, I have a K-Pump K200 and it only take 5 1/2 minutes to inflate both pontoons from scratch. But, since I leave them about 2/3 full hanging in my workshop, it only takes a minute or so to get them up and running waterside.
As for the cup holders... I usually bring Capri Sun juices, a camelbak or my water bottle that I store in the pocket. Don't need the holders too much.
Racks and rigging can be a slight challenge. Everything needs to be out of the oar's swing path radius. You’ll be jealous of your float tube brethren because they have it easy; racks are simply made and placed most anywhere. But, you’ll exact your revenge with storage quantity and quality. I had to adjust my first rod holder design (used when I troll out to my spot) for ergonomics. the second iteration works for me but is a little stretch for some. I have an idea for a third, but we’ll see if it’s necessary. Where you’ll be happy is the rear deck. I have storage for my net, PFD, extra gear, my transport wheel setup I made and rocket launchers for extra rods. You can put your trolling motor back there and I’ve seen some bait wells on Japanese toons. Also, you can have your anchor stored back there or use the bracket CreekCo sells. Lastly, I didn't like the way the stripping net bunched up when attached so I made a frame for it so it lays out flat and at a height that suited for me.
Only other thing I can tell you is if you haven’t done a lot of rowing before, take it easy on the maiden voyage. My first time out, I must have thought I was on Oxford’s Crew defending the title from Cambridge at The Boat Race. Trying to set the world speed record on the water, I ruined a tendon in my wrist. It’s taken along time to rehab and recover.
