Any suggestions on adding a temporary third seat in my cockpit area? I take an old timer up to Champlain every year and this year he asked if his adult so can fish with us. My Triton is a two seater, I'd like to accommodate him if I can, not sure how many more trips he'll be able to make (and his son lives far away so he doesn't see him often and it would be special for him). Maybe just a bag chair once we get stopped???
