What's interesting to me about these large racing multis is that they are reaching speeds that compete with and surpass most motor vessels. This is especially true when the sea states are up enough that smaller, faster motor vessels have to slow way down to stay stable.
It's crazy to think that the sailboat is becoming the fastest all-round means of sea travel.
I bet for the $10M price tag of an AC72 you could get a pretty fast power boat... and you wouldn't need a crew of world class sailors to get it up to speed either.
I interviewed Jim Brown recently and he gave me a quick lesson on hydrofoils being the next big thing. I found a video of the AC72 up on it's foils. Can't post here yet but it is on the website at - thesailingpodcast.com/jimbrown
