For the regatta itself, not too bad. The flight from Boston was around $250 roundtrip to Long Beach, shared a house with another team which saved a lot, and I felt the club did a good job with providing food on several nights. Boat transportation was one of the main costs, but Chris Prentice made it as affordable and painless as possible.

Boat preparation adds a lot, but we felt it was worth it to have the boat in top shape for the worlds.

Overall, I though it was a very reasonable regatta to attend- the entry fee was super cheap for everything that was included (thanks Globaltech).
