I have to step in here. The smaller boats were manufactured on the east coast and the larger boats were manufactured on the west coast. I have a Bucc 305. The hull is solid glass on mine and above the water
line where I just put in a Thur hole it is 1.5 inches thick. My deck is not riveted or screwed to the hull, it is bolted. The 305 is a fairly heavy boat, heavier then a Catalina 30. I know the smaller boats had a different build quality. Maybe it came down to whether it was a east or west coast build? Bayliner answers no questions. My boat sails well in light air and doesn't hobby horse when the seas get a little ruff. I wouldn't cross oceans in it, but it makes for a roomy coastal cruiser. Which is why I own it.
