Dunno if this helps any - I've got an 18' Sea Ark. One cooler on the back serves as my leaning post/ seat / food & drink.
Cooler up front for fish & sitting.
Both are the Academy/Magellan 70qt Yeti knock offs.
I have a SeaArk 1872. Limited space. Finally decided on a cooler. I can lean or sit to drive and sit & fish. I bought the Academy knock off of the Yeti 70.
Might as well quit lurking and post.
My 2013 Sea Ark 1872 Pro. Tunnel, sponsons, 135HO. I've added 3-bank charger & fuel/water separator. Saving up for trolling motor & fishfinder.
I fish central TX lakes and bays, flats, rivers down on the coast.
