Vendball review

You’ve done well in your Vendball business. The tennis club loves the product, the members are clocking up more aces and longer baseline rallies than ever before.

Vendball calamity

Life is never simple. The ITF have been looking at the steady increase in serving speeds and duration of deep baseline rallies. They are worried that we’re heading back to the problems of the late 1990s that resulted in the 2002 rules. They’ve decided that the mass of a type 2 ball will stay the same, but the diameter will increase by 6% and the pressure range will change from 70-90kPA to 50-70kPa above atmospheric. Changes will come into effect 1 Jan next year.

It’s a shame that you have to redesign all your tubes, pressure and safety systems.
