​Knotty Oar Marina is your authorized dealer and installer for the  PWR-ARM II (pronounced "Power Arm") automatic powered Bimini top for your pontoon or deck boat. This is currently the only fully automatic Bimini top on the market today. With the simple push of a button, you can go from sitting in the shade to soaking up the sun.


Pontoon boating is all about relaxation and enjoyment. Do you enjoy having to put your Bimini top up and down every time the sun goes down or you encounter a bridge that isn't tall enough? Most of us consider this a hassle and would love to have another, more automatic option. A pontoon PWR-ARM Bimini top offers you that easy automatic option you have been looking for. By simply pushing a button, you can take your Bimini top from the up and open position, to the radar position, to the full down position.


These Bimini tops come in a 51" height from the mounting location, 10' length from front to back, and will work on boats 92" to 102" wide. Color options include Grey, Navy, Pacific Blue, Burgundy, Black, Beige, and Green. The top comes standard with a helm mounted toggle switch which allows for easy operation.


PWR-ARM (pronounced "Power Arm") Bimini tops can be added to almost any pontoon or deck boat. All PWR-ARM components come with a 1 year manufacturer's warranty.
