They got caught on a rock near the end.
That sounds a bit silly, don't you think?
It's not too silly to get hung up on a rock.
It is not good to get caught on something that can damage your boat. They might need help for the situation they are in to get to safety.
It was just a small rock, nothing to be worried about. I guess boaters really don't know what they are doing.
Even if it was a small rock, I don't think they'd want to get stuck on it because it could still damage the boat, which could cause it to sink. I think helping them would have been the right thing to do.
