Hey, Are the boats on Vikings Revenge at Sea World attached or secured to the slide while its descending the drop? If so, how are they attached? I have looked at some photos of the drop but it is hard to determine exactly what keeps the boats on the slide. Thanks.

There is no form of upstop device on the ride. There are road wheels and guide wheels. As for what keeps the boats where they are, there's this little thing called gravity.
