You didn't tell us what kind of boat you have, but I've never seen a flybridge that wasn't screwed or bolted on. They are designed for easy removal/replacement because many have to be removed to meet height restrictions. I would think a boat this small wouldn't have any clearance issues (13'6" without special permits).
There is usually a rubrail or similar cover which when removed will expose the screws or bolts. I've taken bridges off before and it's no big deal. If in doubt, contact the manufacturer if they are still in business. If not, just start unscrewing, unbolting, and unplugging. But I would measure the boat from the lowest point to the highest point on the bridge before I went to all that trouble. If it's less than about 12 feet, it should be a no brainer. If it's more than that, check with the folks you plan to use for transport to see how tall their trailer is. They can obtain over height permits depending on the route they choose to transport your boat.
Good luck!
PS Sorry Howard, I didn't even pay attention to your stage name. You obviously have a Hatt. Give them a call. By the way, the fact that your boat is in your buddy's pole barn with the bridge attached tells me you won't have any problems transporting it with the bridge on. Unless of course that is one hell of a tall door on that barn!
