All SOTAR Inflatables are designed and manufactured one at a time. No other Inflatables are made with such personal care and attention. You are a name not a number (only the US Coast Guard requires a HIN number); each employee knows your name and stands behind their workmanship. Our sales staff will work with you to find out what design will fit your needs. We can suggest one of our successful designs or create a one off custom design just to meet your needs.
