One way to skate sail without the drawbacks of the stand inside wing skate sail is to use a wind surf sail and make an arrangement that enables the sailor to hang out more than sixty degrees from the vertical sail.
My friend Dick Tillberg and I have made several additions and
modifications to the
wind surf rig to achieve this, but without success.
In order to reduce the air drag of the sailor I made a personal streamlining, see photo. A streamlining, which can reduce drag some 80 %, is essential because air drag in ice sailing is very high due to the high speeds and high relative wind speeds. If for example a (stand inside) wing skate sailor would sail outside his wing his speed would be reduced to less than half.
If there is interest I may be able to put together some information on the basics of streamlining, optimal shapes, and how I built mine.

Can it get simpler?||The position of the white pointer directly shows where the direction of the wind is between best lift and worst header, in oscillating wind shifts.
