'88 mastercraft barefooter can be one of several models - none of them close to an American Skier
1st off the American Skier Barefoot Skiers were from '82 - '87, maybe '88 : '82 - '84 (+ a few '85 and only 1 in '86

) these boats were American Skier Volante closed bows with 290 hp chevys no rear seat and Barefoot Skier graphics
'86, '87, '88 American Skier / Barefoot Skiers were Advance hulls which are very different than the volante closed bow
for skiing on skis the Advance hull is the top - any boom work and long line in the curl the Advance is still the top
wake crossing - not so much........ the barefoot skier / volante is much easier to wake cross than the advance
mastercraft also had their hat in the ring with barefoot boats the best by far from mastercraft was the barefoot 200
the 200 was basically a prostar - non powerslot with an outboard for power not an inboard
for inboard they used the then tristar 190 most added a 454 and they called it barefooter or barefooter 190
it can only be better than prostar powerslot (by far one of the worst to barefoot behind ever) and prostar
all 4 of these mastercraft models were very different in one way or another
Depending on what your really after the best bet is an advance or American Skier Barefoot Skier from '86 and up, or '84 or older American Skier 18 Skier - both are great for boom work (no boom extension required and the hull doesn't roll over very much)
if your truly only after barefoot slalom training then find a sanger dx - that's what is still used today @ the 3 event barefoot tourneys
good luck
