I am not certain, but I doubt that a 192 on the factory trailer would fit under a 7' door.
When I stand next to it, the midship cleats are about eye-level and the entire windshield is above my head. I am 5'7", and the windshield is probably 15-18" tall. That would make the entire package 7' or taller.
Also, if you look at the specs, Bayliner says that boat as a hull draft of 1'6" and a bridge clearance of 4'11". I think those two numbers add up to be close to the total height of the boat. I am confident that the trailer holds the boat more than 6" off the ground.
hi ,i purchaced a new 192 last year on a karavan trailer.my garage door height is 2.3m which i think is 7 foot 6 inches,it just went under by about 10mm or 3/8",i have since lowered the bunks by 2 inches.It tows better and is easy to take of the trailer ,can post some pics of the brakets if you ,like ,hope that helps
