FB,
I guess the full answer is it depends on where you are planning on fishing AND how much water they are running. You could safely use it in the long pool at Buffalo City, the confluence of the two rivers, and Rim Shoals regardless of water level. There is a LOT of fishing to be had in those areas. IF they continue to run water you could carefully pick your way around in other sections of the river.
The 16 foot metal boat with a 25 HP doesn't entail the inherent risk of a glass boat with a big motor. ie they move slower and draft less water. I would hate to scratch my aluminum boat up, but glass fractures are much worse. I guess a lot of people have a higher risk tolerance than I do. I would not be comfortable and would not enjoy my fishing in a glass bass boat on the White.
