A lot of the input questioned the stability of the raft and whether it would actually fit on the roof of the Jetta. I had only briefly considered these two components, though fitting on the roof was a critical design factor, I hadn't actually gone through with testing it.
So today I did. I tested the stability of the raft by trying to tip it over while it was on the lawn and I lifted the frame up on to the roof of the Jetta. Both tests were successful!
Next, the deck!
