Maintain VY +10/-5 knots to a safe maneuvering altitude.

Bottom line

Best rate-of-climb speed (VY)—the airspeed that provides the most altitude gain in a given period of time. Once the seaplane lifts off, establish a positive rate of climb to prevent inadvertently flying back into the water. When a safe airspeed is achieved, establish the pitch attitude for the best rate of climb (VY) and complete the climb checklist.
