Hull differences between 21se and 21 big bay

[Tx21se]

Hello, I currently own a 21se and was wondering if the 21 big bay is basically the same hull as the 21se. I know the big bay has a tunnel and less freeboard. I was always under the assumption that Parker cutdown and modified an SE hull to make a the Big Bay. Thank you
