Skurfer!
Blast from the past! I remember them as being pretty narrow, much more than the pretty common 20" width we see in current wakesurfers. Depending on your weight and the size of your wake, it could be ridden. That huge hatchet fin wouldn't make it a great ride though.
Before investing in EVA foam, I'd give it a shot as is, with the sandle bindings to see if it's even close to allowing you to stay with the wake.
Post up if you decide to give it a go.
