Birdnest,
Great choice. We have the 18' Searunner and my only complaint is it is 2' short of what I should have got. You will really enjoy the extra room.
Bankbound,
Yes, I have a rough water story to tell. It still brings shivers to me when I think about it. The boat handled it very well, but I should never have been in the place I was in to begin with. It was a great learning experience, but almost a costly one. My 18' does very well in choppy water and swells. We regularily fish the ocean, but we can pick our days easier than those who have to drive to the coast. Mine handles Odell's and Wickiup winds extremely well, as well as the Columbia and the Snake when we get that far east. We have had zero problems with our Honda 90.
