It is very important that you always ensure that the dinghy is supplied with the correct air pressure. With fully foldable dinghies (regardless of the brand of the inflatable boat), the correct air pressure ensures that the boat is properly constructed. The transom (engine plate) of this type of boats is "clamped" between the tubes by the correct air pressure.
With a pressure gauge, also called a manometer, you can check whether the correct air pressure is present in the float.
It is also important for inflatable boats with a fully inflatable airfloor that the airdeck is provided with sufficient air pressure. If you sail with a dinghy with an airfloor and there is not enough air pressure in the airdeck, it will sail less well and will be less stable on the water.
