I'm not sure that boat was as impressive as it was made to seem, but it was a really cool boat and turned well.
I was at Long Beach too. What a blast.
That being said, I'm not sure it's "difficult" to set up a boat to be competitive, but making them durable seems to me to be the challenge.
As an example, 8 boats started the race, there were 3 running hard by the end of the weekend and one was a rookie.
That's 50% attrition. Holy smokes (no pun intended).
The salt water is pretty tough on the jets. Have you ever been to Idaho or Ming? Long Beach is sort of by itself as far as venue.
