note I'm 6'2" @ 175# with size 13 feet
My brother and I bought a DUO last year and I easily fit in the back and can even squeeze into the front and be fairly comfortable as well. I canât use foam on the bulkhead if I sit in the front, however, I can in the back. I use the stock foam as is on the bulkhead in the back and have the bulkhead pretty much all the way forward. The bulkhead foam is thick though and could be trimmed down if needed but I'm plenty comfortable as is.
