Old town & Hobie kayaks needed for seat measurements

Hi everyone I’m an avid kayaker with a goal to build bolt on seats for kayaks. I came up with the idea because we love taking our 7yr old and 8 yr old kayaking with us. So far I have built passenger seats for the old town pdl132 Bigwater, old town ap136. RiverwatcherLT on here was cool enough to let me measure his 2021 hobie outback yesterday so I will be releasing a bolt on passenger seat set up for that soon. As the title states I’m looking for local people who wouldn’t mind me taking 10 minutes of your day for a quick measurement. Looking for all models. Please check out my website and let me know what y’all think? www.daseatguy.com 

Willing to trade some fresh herring trays for kayak measurements.

If you need measurements for sportsman 120 pdl let me know.
