Dublin windsurfer Oisin Van Gelderen has an anxious wait for verification that he broke the Irish Speed Sailing record yesterday.

"I know for sure my Max Speed of 47.17 knots is the fastest any Irish sailor has ever done" he claims.

The current record, approved by the World Speed Sailing Council, was set by John Kenny in February who achieved a personal best of a burst of 45.3 knots (it's 84 kph) and averaged 42.52 for the 500 metres.

Van Gelderen describes the build up to yesterday's record attempt at the UK's West Kirby venue:

"The wind was pretty strong - 30-40 knots, so I rigged my brand new Pryde 4.7m RSRacing - just to get the hang things. As it turned out, this sail was perfect for me all day (I'm not the heaviest speed-sailor at 78 kgs).

I knew my board was already fast, but I'm also delighted with the sail, which was rigged for the first time and performed straight away without any tuning.
