How many psi for a towable tube?
If you could measure the pressure in a fully inflated tube, it would be around 2 PSI. Most towable tubes can be inflated using one good electric pump or a combination of 12 volt and hand pumps. Respect the inflation pressure Generally speaking, float tubes with air chambers inflate to 2. Psi, PVC float tubes to around 3. Psi and dropstitch float tubes, mainly used by Seven Bass for its flatforms, are inflated to 15 Psi.
How many HP do you need to pull a tube?
For most people, however, 150HP or higher will be adequate. It is also vital to check the horsepower of your pontoon boat before you start to use it for towing water tubes. Minimum Horsepower (115 HP) – Suitable for light loads and calm conditions, allowing for basic tubing with young children. Optimal Horsepower (150–200 HP) – Offers speeds in the upper 30s MPH. Power steering is recommended based on your boat’s toon configuration.The motors used to power tubes need to be able to provide about one horsepower for every 40 pounds of weight. The boat should be able to reach a speed of about 20mph in order to tow a tube. If you plan on towing more than one tube, you should consider a pontoon boat with a higher horsepower.In any event, with 115 horsepower and proper pontoon set up, you can expect comfortable tubing speeds with a crew in the boat… a pretty nimble pontoon boat!Typically, boats for tubing will travel at speeds between 20-30 mph. However, it’s important to always follow local boating laws and regulations, and to never exceed the recommended speed for your boat and tube.
