Why has the 800mm control limit on overhang of the Spi pole been removed?
The rule was arbitrary and served no real purpose. Thus it was removed. The SCHRS rule is not in place to limit the design thinking of boat designers, it is here to handicap boats that are sailed. In fact, some existing designs (eg Tornado, F16) have pole projections in excess of 800mm. It is felt that class rules should control this, if they wish to (as done in F18 for example).
