Graham, I feel your pain. The ball park figure for a weekend open is around £30. Whitstable was £30. Weston are traditionally very good value but the Grand Slam was £30 this year. Even the academy, traditionally expensive, is £33 for a weekend. So £35 is at the top end of the market, but not ludicrously so. The £10 for not sending your form off sooner is the real sting!
The cost of attending sailing events is generally on the up, with petrol now at £1.20 per litre!
