Does anyone know the hatch size on a Sonic? I have a 35 SS. I want to put on of them portable A/C units in and the hatch needs to be at least 12"X12".

Bill I used a Crusair a/c unit when I had it and it fit fine, but I sold it and bought one of these because it was a pain in the a$$ to set up and lug up to the bow:

Thanks Brian. However, I bought a used hatch jobber from a local real cheap.

Tha hatch is at least that big ! My big a$$ fits through it!

. Come to think of it ...my fat a$$ fits too!!!
