When choosing an inflatable boat give priority consideration to the type of valves it has. This over rides all other considerations.

It is an important point to note. The first is that it is difficult to use in the inflation process; the second is that it is equally difficult to put the cap on without air escaping. There are two basic problems with this type of valve. Once the boat is inflated, the funnel is pushed down and becomes recessed. One of the simplest and cheapest types of valves (and which may perhaps still exist on the lowest priced models of inflatable boats) is the simple blow up valve, a rubber/plastic funnel shape with a cap on top. The dynamics of inflatable boats have made tremendous strides since they were first introduced to the market. The most important issue with them is that they should remain inflated while in use. Manufacturers are well aware of this, and as a result have introduced various valves which can be relied upon to keep the boat inflated even with the worst water scenario.

Make sure they will do the job they are supposed to do.
