Looking for the best hydrofoils for outboard motors? If you own a boat, you know the struggle. Boats are expensive, obviously, and can be even more so in the long run if not taken properly care of. You put them through rough waters, so of course, they are susceptible to wear and tear. If not taken care of, this damage than cost you a fortune in the future. However, there is a simple solution to not only ensure the longevity of your boat but also to enhance your boating experience. This solution has a name- it’s called the hydrofoil

A hydrofoil is a simple yet highly effective instrument. In essence, it minimizes the drag experienced by your boat by lifting it over the surface as it speeds up. The faster your boat movies, the more lift it gets. It is a roughly triangular-shaped instrument that is bolted to the outboard motor. With this instrument, you can nearly eliminate the resistance met by the boat on water and experience speedy and smooth sailing. Using hydrofoil has multiple benefits.

With lower resistance, the engine no longer has to fight as hard, and that helps reduce its fuel consumption. With many sporty hydrofoils, you can significantly accelerate the speed of your boat, especially with smaller vessels. You can maneuver the boat with greater ease.  The hydrofoil maintains the stern up and the bow down.

Hydrofoils help to reduce chine walking and porpoising, and also allows greater visibility especially at lower speeds. The lack of excess burden on your motor further helps improve its life span and adds a few years to it. You can save money on repairs that way. You have greater control over your vessel with a hydrofoil attached to it. You can experience a safe and stable boating experience with it, without spending a lot of money.

Things to Consider before buying Best Hydrofoils For Outboard Motors

  • Compatibility with Boat: Ensure that the hydrofoil is compatible with your boat. No single hydrofoil fits every boat perfectly. Each hydrofoil is compatible with certain types of boats and not with others. Generally, compatibility is considered in terms of motor horsepower (HP). If it does not fit your boat right, you are unlikely to achieve the results you seek.
  • Material: Hydrofoils come in different materials. The most common material used to construct hydrofoils is sturdy plastic. These are the most common ones. If you do not prefer plastic, you can opt for metal hydrofoils, many of which are built from stainless steel. These are durable and lightweight, albeit more expensive.
  • Durability: No matter what material your hydrofoil is built from, just make sure that it is sturdy and durable. While the plastic used by most brands is strong enough, it cannot beat the strength of stainless steel hydrofoils.
  • Installation: There are two types of installation methods for hydrofoils- drill and no-drill mounting. Of course, the no-drill type is easier and faster to mount. You do not have to worry about damaging your motor while drilling into it. They can be installed by anyone with little effort. On the other hand, those that require drilling are more difficult and time-consuming, but they are guaranteed to stay put and not fall off your motor as the no-drill type could.
  • Speed: Some hydrofoils are designed to help you gain speed. These are likely to have streamlined bodies that can easily cut through the water. However, the ones that improve your speed performance are likely to be more expensive than the average hydrofoil.
  • Size of the Boat: Take into account the size of your boat when choosing your hydrofoil. Make sure that your hydrofoil is compatible with the particular size of your boat. Generally, hydrofoils show their results better in smaller boats than in bigger ones.
  • Fuel Efficiency: The use of a good hydrofoil will considerably reduce your fuel consumption. They do so by reducing the bow rise and making way for rapid planning.
  • Budget: Hydrofoils come in a range of prices, some with more features than others. If you do not have a large budget to spare, prioritize your requirements, and opt for a hydrofoil that only meets your major needs.
  • Warranty: Make sure that hydrofoil comes with a warranty for a considerable period of time. Also, check to see that they have a good customer service system in place.

DOES THE SIZE OF MY BOAT MATTER?

Hydrofoils come in a range of types and they are compatible with different sizes of boats. Every type and size of the boat can truly benefit from installing the right hydrofoil.

While it is usually used with commercial ships, more and more private boat owners are using them with their boats due to their numerous benefits.

So irrespective of the type of your boat and its size, you can benefit from the presence of a hydrofoil. It is known generally that the smaller the boat is, the better the improvement in its performance when mounted with a hydrofoil. It can show an improvement in larger boats too- if not in speed, at least in fuel efficiency and smoother performance.

FAQ

How do the hydrofoils function?
Hydrofoils works on the basis of what is called ‘Fluid Dynamics’. This concept essentially states that the speed at which water moves above the hydrofoils is faster than the water below it. This results in the development of a drop in pressure that leads to the boat lifting. Since the hull is above the surface of the water, the resistance it meets is less which leads to less strain on the motor and less fuel consumption
Which is better- drill or no-drill hydrofoils?
Both types of installation methods have their advantages and disadvantaged. The no-drill type uses a simple clamping mechanism to mount the hydrofoil. This is, of course, an easier method. These can be installed by anyone with little effort. It saves you a significant amount of time during installation to mount. You do not have to worry about damaging your motor while drilling into it. However, it is likely the clamp might loosen and the hydrofoil might fall off your boat. On the other hand, hydrofoils that require drilling for mounting them are more difficult and require certain tools. It is time-consuming. These hydrofoils help reduce bow rising significantly so you can plane even at lower speeds. However, these hydrofoils are guaranteed to stay put and not fall off your motor as the no-drill type hydrofoil could. 

CONCLUSION

Owning and maintaining a boat is, of course, quite an expensive task. However, you can minimize long term costs by investing in a good-quality hydrofoil. They are energy efficient, and with the reduced resistance and drag, make sure that the boat consumes less fuel than when it is without a hydrofoil. It also adds to the longevity of your boat as the strain on the engine is reduces. Therefore, installing a good hydrofoil will be a smart decision to make in the long run.
