Final Fantasy X problem

[DAG101]

okay, I borrowed a copy of the game, NA version, for my PS2. Whenever I get to the part on the ship after leaving Beseids, when Sin attacks (I've gotten past this part before), and the game zooms out to a view from behind the ship. that part just loops (the ship stays still, but the paddle wheels move, as does the water and clouds). Anyone know what the problem is?

It's been a while since I played X, but if I remember correctly it'll just keep dragging the ship around like that, eventually it will give you a chance to attack only long range attacks work like Wakka's Blitzball, Lulu's magic, or have Yuna summon Valefor.

It doesn't start a battle, or show Sin, but I'll try letting it sit for a while.

At that point you don't fight Sin himself, just his fin the battle it just takes a while because the boat keeps changing direction.
