Project Summary

For the transportation of the classic America Cup M-class wooden hulled sloop PURSUIT from the Svendsen's Bay Marine Yard in
Point Richmond, CA, to France, a steel lifting and transportation cradle was designed in which the hull was stowed. The strenght of
the cradle subject to lifting and transport forces was verified using Femap FE analyses. After construction and stowing the 95,000 lbs
heavy sloop PURSUIT inside, using the yard's Travelift, the cradle was lifted onto a sectional Poseidon barge for the tow from the
yard in Point Richmond to the container terminal in Oakland. The barge dimensions were limited by the Travelift wheel pier distance
and its stability was carefully checked. After arrival in Oakland, the cradle with sloop was lifted and stowed inside the hold of a
container ship, using a STS crane with a hook under its headblock. The cradle was lashed to its supporting flat racks for the long
voyage to France. The cradle with sloop safely arrived in France late December 2023.
