I cant imagine you are alone here. There seem to be so many of those boats around, at least here there are.
A good friend of ours has one, it seems a pretty fast boat. Although going down below for any time under seems to turn people green. Something I never experienced in either of our boats.
Really ...my wife will be delighted with that!! I'm sure it's a matter of adjusting....to my knowledge we are not overly prone to motion sickness, having sailed with friends on like size boats, over the years.
Speed is a lesser concern, but should create some fun....we are on Lake Nipissing and it's roughly 40 x 20 kn....certainly no Lake Superior, but I think it will suit us fine.
I am familiar with lake Nippissing. I grew up just south of North Bay by about 25 miles. The only sailboats we saw as kids were daysailers and dingys. I see now things have changed.
