All Aluminum models except, the AVX181, 189, and 188C have the .125 hull thickness. The listed 3 models have the .100 thick hulls.
I just added about the transoms if someone didn't know already. The AVX 181, 189, and 188c have the .100 thick hull.
the other boats in the lineup have the new .125 thick hull.
from a phone conversation and text from one of the reps yesterday. sorry if throwing in the transom caused confusion.
