Hanging the bow fenders on many boats is uncomfortable. Now, using the Automatic Fender™, we can dock without leaving the Cockpit!

The Automatic Fender deploy the bow fenders with a single push of a button, without the need to climb on the boat's bow/deck. The fenders are stored horizontally under the railing, almost invisibly. The Automatic Fenders are made of a very durable, white and shiny Polycarbonate/ABS material. They blend nicely with the boat; making them almost invisible. 

Fender height from the water is set to support different height docks and rafting/tethering (boat to boat) tying. Installation and operation is very easy, requiring only three clamps to connect (no drilling). The Automatic Fender comes with a rechargeable battery, charged using a solar cell and Bluetooth communication. 

To avoid expert installation or any electrical connection to the boat, we made significant investments in extremely low power design, large solar cell, large batteries and easy to install clamps. For maintenance-free long-lasting operation, all electronic parts are sealed and conformal coated. 

         The Automatic Fender supports operation even in cloudy regions and covered docking. The horizontally facing, large solar, provides defused light charging in shaded areas. 

Due to its large battery and very efficient power operation, the Automatic Fender can be stored for winter in an indoor storage and will still retain power until Summer. It will retain power even if the boat stays in storage for 3 years! 


         It takes only 2 sunny days a year for the upward facing solar to keep the batteries fully charged. 

The Automatic Fenders can be controlled from any location on the boat, and are delivered with a unique username and password to prevent unauthorized operation and deter theft. The Automatic Fender supports up to and including 10” center (through) hole fenders (28” in length). 


The Automatic Fender eases bow fenders deployment in Cruisers, Fishing boats, Offshores, Speedboats, and any boat with inconvenient bow access. In most boats, stern access is convenient; therefore, we do not promote the Automatic Fender for the stern fenders. In large boats the Automatic Fenders can be used as the bow and midship fenders. 


From all fender Baskets and fender storage solutions they are the best looking. The fenders are stored horizontally under the railing, not blocking the captains view. 

Designed and manufactured in California, USA. Shipping worldwide.

The Automatic Fender™ Design

Our objective was to build a beautiful, very strong and durable product, which is very simple to install and operate. This required an innovative design:


Withstanding the line tension while docking

The lines tension while docking may be very significant. Withstanding that tension without building a very large and expensive product was one of the biggest design challenges. To handle the line tension/force we tested thick docking line implementations, a spring addition, a rubber strip addition and quite a few additional creative options. Testing showed that the best solution is deflecting that force by using a strong, Nylon line. Nylon is a good shock absorber. The longer the line, the better it absorbs.

When manually deploying the fender, the total line length from the fender to the cleat or stanchion is about 4 feet. The Automatic Fender’s Nylon line is 18 feet long and provides a good shock absorbing effect! It runs from the stanchion or cleat to the center hole fender and back to the Automatic Fender; the remaining line is being stored in a pulley inside the Automatic Fender. 

Adding a shock absorbing line reduces the stress on the Automatic Fender, the boat’s cleat or stanchion, and on the center hole fender.

Product longevity

To achieve the best longevity and maximum strength a 50% Polycarbonate and 50% ABS, high pressure, custom made injected enclosure was developed. All bolts and nuts are stainless steel. All electronic parts are CRC Urethane conformal coated and are stored in a sealed enclosure. The solar cells are PET coated!


Easy installation without electrical connection to the boat

To reduce overall cost (product plus installation cost), the Automatic Fender can be installed easily by the boat owner. The product is self-contained using a Lithium Ion battery and Bluetooth connectivity. No electrical connection to the boat is required. The battery is kept charged by two solar cells:

  • On sunny days, while being exposed to the sun, the top cover solar cell is the main energy source.

  • On cloudy days or while under a covered area, the large solar cell in the front of the Automatic Fender charges the batteries using diffused light. 

Battery power management

While not being exposed directly to the sun, the large Lithium Ion battery can maintain power for about 9 months! That was achieved by:

  • Detailed power management of the Automatic Fenders Printed Circuit Board (PCB). The PCB is divided into several power sections and each section is enabled only while used. That way, very minimal power is consumed while the Automatic Fender is stored or not being in use.

  • Power management of the Bluetooth communication component: when the battery is fully charged and having strong irradiance the Bluetooth will “advertise” frequently and get connected seamlessly. When the boat is in storage or when the battery level is critically low the Bluetooth component is being moved to low power consumption mode (conserving power and connecting slightly slower).


The Automatic Fender is continuously being tested in two environmental Chambers:

  • The first Chamber running temperature cycles -25 degrees Celsius (- 13 degrees Fahrenheit) to +75 degrees Celsius (167 degrees Fahrenheit)

  • The second Chamber constantly at + 75 degrees Celsius which is the most extreme temperature

Both Chambers are at about 95% humidity and contain salt!

The Automatic Fender was tested while being underwater!

The Automatic Fender functionality is continuously tested on the company’s cruiser and running lift / deploy cycles in the lab. A Few Automatic Fenders ran more than 200,000 lift / deploy cycles without a single failure!

The Automatic Fender will give critical health alerts about the system from remote, with an Onstar like monitoring system if necessary!


Theft deterrent

Each Automatic Fender has a microprocessor and a unique identification number. The identification number is stored in the company’s server with the user’s unique username and password. Each Automatic Fender can be operated only by its assigned user!


Ease of operation

Username and password can be stored locally on your phone or tablet. The Automatic Fender application can be downloaded to multiple smartphones and tables. To allow seamless transition between different phones and tablets, all parameters and status of each Automatic Fender are saved on our server. We do not have access to and we do not store any personal information. We have access and store only information directly related to the Automatic Fenders.

Automatic Fender cost drivers:

For the highest strength and durability, the product enclosure is made of high pressure, custom injected, Polycarbonate/ABS. These parts are the most expensive component in the overall product cost. All bolts and nuts are stainless steel, which provides the best longevity. The line is made out of strong Nylon and is 18’ long!

To allow a very easy installation with no electrical connection to the boat, two solar cells and a large Lithium Ion battery were added. Allowing electrical connectivity to the boat could have reduced the product cost but would have increased the overall cost (product plus installation cost). Therefore, a self-contained design, with no electrical connection to the boat was chosen.

The batteries used are Lithium Ion, which have many advantages (described in the Q&A section) but are higher in cost. The Automatic Fender is designed and manufactured in the USA.
