Did i read that right?
60Kts will break the shrouds under bare pole on the beach?
in answer to the question: you live in florida, if it's not storming and you're not scared of whatever wind my be blowing ahead of the current approaching front, go on out and have fun. the 6.0 is prolly too big a boat to carelessly tip over, so some discretion is advised.
as far as sailing in high winds: the most i ever raced in comfortably was well over 22knt. average, although i agree that 22 is a really fun windspeed. we were at coyote point in the sf bay delta at a hobie points regatta. the committe boat claimed 50mph winds by the meter. the water isn't too rough there and we were on a H16. we were used to sailing the ocean at santa cruz, so the delta was pretty easy for us. it felt like about 30-35knts to me, so i expect the 50 was a peak. i have attached a picture of the day from the late 70's. i know it doesn't look that windy, but the water is protected there. so, proof positive can handle more wind in smooth water than in rough seas. granted rough seas with light wind is one of the worst senarios tho.
prolly one of the strongest winds in a race was the stilleto nationals one year in FL when a light hurricane blew through at the start. all the boats but us ended up on the leeward shore by ripley's museum. our main halyard had broken just before the gun. our skipper a former footballplayer/boxer was hand holding the jib whilst flying the hull on the stilleto 23 on a close reach or beat, i don't remeber, back to our home beach. what a day. after the wind died a bit i went windsurfing with a small sail like a 4.0 or something. i don't think the RC thought the storm would come our way.

Here on maui i believe 22k average would be like a 5.0 or 5.5 sail on a wave board and is a moderate day. The full trades aren't that comfortable for a cat, but if i had a 90% shorter rig i think it would be comfortable. the average cat is rigged for 1-22knts. in general so you can see why there is a problem with the higher winds. we have had 4 people on the boat w/2 on the wire and it was fairly comfortable. although i didn't try any death reaches. mostly i just go upwind and downwind in the big winds.
cheers
