Description

Bridge the dangerous gap between your boat and dock with the Boat Boarding Platform and Dock Extension from Extreme Max! Designed with safety in mind, the extension reaches out from your dock, providing a sturdy, sure-footed way to ease boat entry and exiting. Its removable handle is especially welcome on wavier days or for people with compromised balance. A clever hinge system allows the extension to be lifted into a vertical position when not in use, allowing worry-free docking. It is constructed entirely of high-grade aluminum, keeping it free from rust and other damage common in marine areas. Not to be used as a jumping platform or diving board.

    • Solid aluminum. Solid Product.
This dock extension is exactly what I was hoping for. It’s made of solid aluminum, and built solid, too. I had seen one (4 star) review talking about the sharp edges underneath the platform. I understand their concern , but a little selective filing smoothed those out nicely. You do need to supply the hardware for mounting through the four (4) 1/2 inch holes, but that’s understandable. Not all docks are built the same. We were able to utilize 1/2 inch lag bolts. Overall, this product delivered exactly what I needed.👍. ... show more

    • Exceeds expectations
Easy to install, perfect. It’s much safer using this to reach out to the Boat. We love it and I’ve been using it now for six months. Highly recommended and it even supports very heavy people :-)

well made. i deducted a star for the screws that came with it. I wanted the diameter of the shaft of the screw to be almost the same as the holes (included ones were smaller which might allow for movement). bought galvanized ones at lowes. I installed some wood support below the decking to strengthen the area of installation. feels pretty solid. it would be nice if you could mount the handle bar to either side, but you can't obviously. also would be nice if it were wider, but no options really out there. ... show more

    • High quality construction and value

Very well built and designed platform that was easy to adapt to feature steps. The finish also is of a high order, as is the mechanical design and overall quality. The finished adaptation (which swings out of the way when docking or boat lowering—neither illustrated here) could not have worked out better. ... show more

We are 85 years old, and this fabulous product enables us to board our boat safely and continue enjoying it. If you look at the attached pictures closely, you will see that I used a 2 x 6 board to space the boarding platform away from our dock to insure that the mounting lag bolts (don't forget the washers) were firmly secured to the supporting structure of our dock. This product helps us to stay safe. ... show more

    • Great dock step
This is a great and easy to mount step. I have 2 and they’ve worked great for years. Makes it super easy to get on and off our boat at the dock.
