Oh, the Tsunami is a great kayak, No-No, you'll be thrilled! They come in different sizes, and I can't remember the one I used, but at our local paddling club it was my favourite starter kayak and there's an even smaller childrens version that fit my son perfectly. Everything perfectly downsized to fit a small 12-yr-old, really nice.
I took my kayak out yesterday
Had a borrowed, too big drysuit and wanted to practice cos I was worried I couldn't slip out of and climb into my kayak easily wearing it. I felt so unstable getting out into the water - but the minute I sat down properly I just felt this "aaah, I'm home!" feeling 
Tell us all about it when you get there! What a bummer having to wait, but it will be so worth it.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
