I read this some months ago now, but have been thinking about it again lately...
From an ASP press release from 10th October 2009
Prize money at the ASP World Tour and ASP Women’s World Tour level is set for a substantial increase in 2010. Base prize money for the ASP World Tour events will increase from the current US$340,000 to US$400,000 in 2010, taking the total prize pool on 10 events from $3,400,000 to $4,000,000 per annum. On the ASP Women’s World Tour, total prize pool will increase from US$630,000 to $800,000 in 2010.
Along with the increase in event prize purse, an additional US$100,000 bonus will be awarded to the year-end ASP World Champion, as well as an additional US$30,000 bonus to the year-end ASP Women’s World Champion.
I realise that there are differences in the numbers of surfers allowed on each tour, but nonetheless, the disparities in the rewards on offer seem overly significant.
