I got smashed with a 5.8 on the river. The longest I was standing was for around 300metres... the wind was all over the place very messed up and hard no matter what size you had I reckon. I was doing aqua aerobics most of the time
I lasted about two minutes in SB with 3.7. Just checked the graphs and it was between 30 and 49 kn when I was there. Not the brightest idea I've had this week... Even rigging up was a challenge
