TO RULES COMMETTEE PLEASE READ – Nationals no ballast day
If you read the rules you will find that it is the ASH-26 that is at a
competitive disadvantage at a no-water contest, not the Diana.
This is because the lighter gliders are allowed to add fixed ballast, while
the heavier machines have no way to get rid of it. In a weak weather contest
the Diana has the advantage while the 26 grovels, but in a strong weather
contest they are equal.
Point two: The rules for nationals provide for a no-water day to be called
only for compelling circumstances, that is to say weak. Here again, the
lighter glider would be at an advantage.

Nationals can now declare a “No ballast” day without all pilots
agreeing.
A motor glider or a heavy glider will have a considerable advantage
especially on a good day if this rule is not modified.
Here is an example, imagine Diana 2 (420 lb empty with instruments)
competing with ASG-29 15 m (620 lb empty with instruments). A no water
day was called.
Wing loading for each glider in a typical configuration (180 lb pilot
weight)
Diana 2 – 6.45 lb/sq foot.
ASG-29 15 m – 8.08 lb/sq foot
Diana 2 pilot does not have a chance. This glider needs some water to
fly at the same wing loading as other heavier gliders. There are more
examples I could give but I think my point is clear.
Please put a restriction on wing loading for those days when no tow
pilot wants to tow a fully loaded glider rather than declaring a “No
ballast day”
The intention of this rule was good no one wants to loose a day, but
please don't create losers.
