    Britannia now has an appendage running back from the stem underneath the hull. They haven't said what it's for, so speculation is rife: stiffening the hull? centreboard for direction control during touchdowns? Close the gap between hull and water for an endplate effect?

    This will increase the drag of air.

    There is also a red object beside the possible endplate. Maybe an inflatable device to lower the "endplate". The "endplate" will also make turning the boat, when hull-borne, more difficult.
    But I think these objects are just parts of the support/protection when handling the boat on land.

    The red object is the reflection of the piece of machinery sitting on the ground below the boat.

    While nothing else is happening…

    Luna Rossa testing launch mode (America's Cup: Luna Rossa take off... con commento tecnico | Farevela.net https://farevela.net/2020/05/11/americas-cup-luna-rossa-take-off/):

    Kiwis experimenting with bulbs (Richard Gladwell photo I believe):

    The thing on the inboard end of the foil is a pair of cameras apparently.

    It seems teams are still planning on arriving in NZ as early as they can before December, maybe September. Things might get a little more interesting then.

    Video of the Luna Rossa launch. It seems it was caused by rudder ventilation shortly after a gybe, causing the stern to sink hence the bow–up attitude. They recovered pretty well and kept sailing.

    NYYC's challenger Defiant has arrived in NZ. Put straight into the water and towed to the team base, the cradle went by road. It will be great to see two AC75s on the water, though not sailing together in a "coordinated way" just yet. :)

    The Prada Cup conditions have been posted. A 12 race round robin series will be held for the three challengers, with the leading boat going into the final. The other two boats race in a semi–final series to see which also goes into the final. The two finalists then race to see who goes into the AC match against ETNZ.

    American Magic is out of quarantine and should be sailing soon.
