Query: Flimsy and fragile

We were disappointed that it took more time to inflate this boat than the time that we could enjoy it. The boat was comfortable to sit in on land. In the water, the boat is hard to steer and kept turning in circles (we are experienced kayak users). Ten minutes into its maiden voyage, our boat brushed up against a stick and tore a 6 inch gash along its bottom. Vacation ruined. When I contacted their customer service, they sent me a polite acknowledgment email, but nothing more - NO HELP!
