Mine is a sit on top. They are easy to roll, even the big Hobies,so Hell no to my legs being inside anything. The more stable they are the heavier they are. Do not even consider anything under a 12' one for a grown man. one more thing is watch the load limit. You want one with a load limit of at least 400 lbs. Lower load limit sits lower in the water too. Mines a Native Slayer Propel 13" I bought it off Facebook market place one year old. Don't think you can get anything you can fish out of all day both comfortable and safe for less than a grand.
