Use your oars to get out there quick and use your fins to troll or move around. That's what I did when I had a pontoon as well as a float tube. The Gigbob has been around for a while. Interesting design to get a float tube and a pontoon in one package almost 10 years ago.
The higher seating position of a pontoon is a boon for fly fishing and maybe just fishing in general. Easier casting and sighting is much better. I even raised my pontoon's seat another couple of inches on the frame to gain more of an advantage. Even modern "sit on" tubes are better than the old "belly boats" in those respects.
One bad thing though, you're more a sail when it gets windy. I guess that's the nice attribute of the Gigbob. Pontoon the morning at Crowley, then around 11:30, come on in and break it down into a tube for the afternoon howlers. Nice.
P.S. OBob - need to rent a Hobie Kayak with pedal drive. Yeah, a little tough to manuever but you don't see any tubers or tooners out at the middle or long beach wall. Buddy just got rid of his Hobie... only because his kid is ready to hit the water with him, so he needed a boat.
some bait and wait, some troll

With fins on, just manuever to keep fish in front of you. No big deal. Oars not as bad as you would think.
