I don't like the added ropes. The other half of the blooper is really the edit between the wide shot of the skiff being hit and Han hanging from his feet. The stunt double in the wide falls and hangs from his arms, then Han is seen swinging from his feet with his hands below:

I think it's supposed to look like Chewie grabs Han's feet before he falls, but the extra few frames showing his boot tips touching the skiff edge removes that intention.

But these sorts of continuity mistakes happen all the time, so it's not a bother.
