The take home lesson was that until they got securing the uhmw to the bottom down pat, it was a no go. This was a couple of years ago and it was very likely a DIY job... can't remember all the details. I know the benefits of the stuff are certainly a plus.

Gotta admit though- it would be pretty cool to see a DB get pole vaulted by its bottom! Unless of course you happened to be in the boat at the time.
