Shark kite

After Lucas, a kite flyer friend and excellent builder, with infinite patience... sent me an email with some photos of a very cute inflatable shark, telling me that he wanted to do it but did not have the plans; almost a gentlemen's challenge, and how could it be less I took it. I started searching the internet but I didn't find many models or photos, let alone a plan! Therefore I started by drawing a side view of the shark, to later see how I achieved the inflated volume!
