I would go. I did go, last month. Gust of 46 and 54 recorded with constant 25+ knots. I was sailing a Laser with radial sail. I should have reefed it once but did not.
While I did end up getting demasted that day, it was not so much due to the wind as my not knowing the depths of the area I was sailing. I was heading back into the marina when a gust put me down and when I righted her she had lost half her mast to the mud bottom.
Anyway, those conditions are fun for 30 minutes to an hour or so but ONLY if you KNOW what your doing and how to beat up in those c0nditions. Also, head downwind from wherever you leave to make getting back that much easier.
Sheet in tight, cleave the wind, hike it out and letter ride man.
Just make sure your rigged for the conditions. One more thing, check your rudder attachment points REAL good. That was something that cost me a month ago..
