    Some great pix from Emirates Team New Zealand's AC72 riding on the foils of the dagger boards and the rudders. You can really see the shape of the dagger board and foil. Interesting how much like l'Hydroptre ETNZ's AC72 looks.

    Comments by Grant Dalton about the foils.

    The question remains: can foiling be sustained safely on the short America’s Cup courses.

    Emirates Team New Zealand managing director Grant Dalton said all the teams will be testing foil design so there will be no surprises there.

    “The thrust of our testing is to determine if foils enhance performance overall. How will they affect upwind speed? Might that nullify any downwind gain?

    “In addition, the effect on boat-handling in upper wind ranges needs to be assessed carefully.

    “There is a tendency for the boat to dig in when it is bearing away and the placement of the
    dagger foils and their shape has a marked effect on this.

    “Foiling is only part of the equation. Right now we see as many negatives as positives.”
