    There was a further update from Len Surtees on his Sting 600 before Christmas which I forgot to post.

    His website shows the renderings of the forward foils:

    He is hoping to be getting the foils progressed this month I think with some further videos of the foils as they are developed and is hoping to be foiling in February.

    Charles Heidsieck IV has nothing in common with the Fire Arrow Foil System except a foil on the daggerboard. The Fire Arrow Foil System is a trimaran flying system that includes an adjustable lifting foil on the daggerboard capable of downforce*, an UptiP foil on each ama and one or more rudder T-foils. And for smaller tri's a Two Stage Ama.
    Heidsieck was also too heavy to fly and performed poorly.

    Excerpt:
    VPLP: On these big boats, when you ease a sail, it is a pain because it takes so long to grind it back in. But here you press a button and the angles of incidence change. And with the foil on the daggerboard you can use it to alter the flight according to the wind.** If it builds, rather than easing the sheet you increase the righting moment by increasing the angle and conversely, as it eases you can reduce it and let it fly more.
    ** done 100% automatically on Fire Arrow/WOLF with the wand controlled main foil.

    Delusional, much?

    Update from Len Surtees on the 600 foiler:
    Hi Doug
    Processing slowly, December was lost and February is same.
    Am currently interstate working and not home till 25th.
    Then finish foils, plugs are done, a jig to set up foils is completed which means next step is to lay up fiber glass molds.
    Hopefully first tow test can be started here at Tin Can Bay by late March.
    Plan is to tow test without rig, then test with rig up till confident all is working well.
    The local waterway is limited for foiling so plan to drive 1,000klm down to Lake Macquarie for sail testing, this is same place as sailing video was taken.
    This is a deep and very large lake which is tidal influence but is perfect for foiling.
    We will carefully document all aspects of testing and will put a video out showing external and on board footage.
