The blue cradles support the ship, but the red transporters carry the weight as the cradles are raised off the ground.
This is in preparation for tonight or tomorrow's move onto the barge Boa Barge 37. On Saturday morning the barge, with ship aboard, will be moved to Bedford Basin anchorage for the "launch" , or more properly "float off".
The ship will them be moved back to the shipyard for continued fitting out. With the hard stand area free, it is expected that AOPS 2 will very soon move out from the Assembly Hall.
