The "X" series Xpress Bass Boats are a different animal than most tin rigs, as they use the hyperlift hull design. They have better performance numbers than any mod-v and most other manufacturers' offerings, and ride much better in chop. That being said, they are not glass boats and never will be.
I don't think they'll dissolve if salt water touches them, but I will not disagree with Pat about rigging a boat properly to run in salt.
If you're not living on the edge, you're taking up too much space!
