Newbie Finally Ventured Out

Hey All! Just bought my Kokopelli Nirvana and did my first short Solo. It is so different from my sea kayak or WW kayaks I am used to.
I found the odd feeling being right on the water and my heels were awkward any suggestions? The new Nirvana have a fabric back so only have a blow up bottom. Not many packrafters in calmer waters yet in VA.
