H77,
I must admit I rarely think about it and I almost always sail in big wind often with big waves. The H16 is so great in waves - maybe partly due to this "give". I've read that many people feel it may be the best all 'round cat in waves, surfing, etc.
I must say I've never been in a situation that I noticed it on the water nor found that it hindered anything. I'm usually trapped out and holding on for dear life. In these situations, hull slop is low on my priority list!

Cheers again and good luck
Ron
