Water inflatables go by a lot of different names from towable inflatables, water inflatables, boat towable and inflatable towable, and whatever you call them, they are a lot of fun for everyone who rides one.
There are some safety issues you should be aware of, make sure you are towing in an area that is not very busy with other boaters and that you have enough people so that when you are towing someone and they fall off the boat driver can be advised and get back to the person that fell off and the spotter should have a red flag to put up as soon as someone falls to alert other boaters that someone is down. You want to make sure that when you are going to ride the inflatable you have a good life jacket on and if it is an inflatable that holds more than one person all riders should have a life vest on.
There are a lot of manufactures of inflatable towables and all have some very fun styles that hold from one to several people and from as much as a few dollars to several hundred. The internet is the best place to buy a water inflatable because a brick and mortar store could not possible stock all the towables that are for sale. When you purchase an inflatable make sure you get a rope that fits the size of the inflatable and the number of people that will be riding it. Some inflatables can do a lot of different things by shifting your weight or how you hit the wake and usually when you hit the wake that is when someone will fall off so you want to make sure the spotter stays alert. The more time you spend on the water the inflatable the more things you will find that you can do with it and just remember always be safe. Some of the main supplies of inflatable are Sportsstuff, Aviva Sports, Airhead, O'Brien, Rave Sports, Body Glove and Full Throttle. Sportsstuff probably has the largest selection of inflatable toys for you to have fun with and each year come out with new exciting toys.
There is some care to owning an inflatable you do not want to leave them in the hot sun fully inflated and if you are going to store them put them in a cool area and let a little air out. When you are inflating it, it is best to us a good electric pump because they do require a lot of air and you do not want to spend your whole trip trying to fill your inflatable, fill till all the wrinkles are out and you can stand on it without sinking in more than a couple of inches.
