I've got a 40' Oceanis.....

i've sailed it in upto 40kts of wind, and large seas, and it handles them without any real concern at all...

Yes, we've had a bit of slamming when motoring upwind into large seas, but even then, a good helm can reduce the slamming significantly.

Never once have I worried about hull strength or integrity.

I would happily (and indeed intend to) cross oceans in her.

We too can echo the comments above... in perhaps 20kts of wind, we are trucking along, and can often overtake many heavier boats who are busy pushing the waves out of the way rather than going over them!...
