I don't really touch the boat sides with my hips cause I'm not a big paddler .I would say that only my ass and back are making a contact point with the boat.
I have seen picutres of thin women in a ELITE so I'm wondering if it is important that my hips should stick to the sides ?
Not at all. I have the same dimensions as yourself and have no issues. I use a but pad which stops me sliding around in the cockpit but I have never felt the need for a more snug fit.
