Outside of the ex ruining your boats (how awful) that's an amazing story. That would have been quite some experience, working on those full size boats.
I'm not sure we have any of the big unlimited's in Australia, but it's great to see how bit it is over there. My Grandfather used to take me to the yearly power boat spectacular at St George Motor Boat Club here in Sydney, and I fondly remember 2 of them showing up, tilted on their trailer, cranes ushering them into the water. I was in awe, a young kid next to these giant machines. I'll never forget it.
