The inflatable boat uses inflatable PVC air bag as boat hull, it has at least five or more air inject mouths, once one air bag fails, others still work, so it¡¯s safe for you. And we have safety jacket for each user, there are oars for each boat, so the boat can be rowed forward even the engine fails working. Our boats are equipped with 2 stroke 43cc or 47 cc engine, the speed is not as fast as those speedy boat driven by bigger displacement/power engine. Yet they are much faster that those normal boats without any motors. This kind of boat is really a very good tool in a lake or small river, it can work as a fish boat or a tourist viewing boat, or a rescue boat in emergency case, esp. in flood season, wherever those big motorboat cannot go, yet such boats can go anywhere.
