One additional point of consideration on the Stabicraft. Its a 2013. According to the Stabicraft website, they started filling the pontoon 'life ring' with foam in 2015 - I think models before that just used the pontoon as air chamber flotation (not sure if its multiple chambers or one single chamber).
Just a point to consider and potentially investigate to an interested party. Honestly on a 10 year old boat, its likely better if it has no foam - you could have it filled yourself (i'd just have it pressure tested and then keep it as air chamber flotation if it were mine).
