Product description
For a quick grab and a maximum hold in offshore anchoring, set your eyes to the Extreme Max Cube Anchor! The unconventional design of a cube anchor shines where conventional-style anchors falter. No longer will you have to drag your anchor until you feel it hold or question whether or not it set, the cube anchor sets almost immediately upon impact and adjusts its hold and positioning in changing winds and currents without having to be manually maneuvered from the boat. When the parking is finished, the cube anchor quickly releases from the bottom and collapses flat to save space on your boat.

- Reviewed in Canada on September 3, 2019Verified PurchaseGreat product. Used it for the very first time this weekend at White Sands beach in Osoyoos, BC. The beach can get quite busy and the anchor held our Super Air Nautique 210 with ease. We purchased this anchor after seeing it firmly hold our friends 23 foot Tige. Setting the anchor is a breeze ... Just throw it in and it does the rest for you. Build quality is very good as well. The best anchor we have ever owned.

- Reviewed in Canada on July 12, 2019Verified PurchaseThis is a smokin deal (as much as any $100+ anchor can be a deal). Honestly it is very well constructed and finshed. Holds like a rude pitbull with a Maltese in its maw. I’ve tried navy anchors and danforths etc. none set with a fraction of the ease and none could hold in a medium breeze. Our lake is fluffy mud, weeds or both. This box anchor sets immediately and holds no problem.
- Reviewed in Canada on July 30, 2021Verified PurchaseHas worked flawlessly. Very pleased
- Reviewed in Canada on April 13, 2020Verified PurchaseExcellent product for the price. Haven't used yet, but should perform as any of the other box anchors. Typical good quality and value that Extreme Max products provide..
- Reviewed in Canada on October 27, 2020Verified PurchaseDecent anchor for 16 to 22 ft boat
- Reviewed in Canada on December 2, 2019Verified PurchaseJust works perfectly as described. Holds my 22' Wakesetter WAY BETTER than any other anchor system I've ever tried.

Holds my 23.5’ Mojo with no problems , get the anchor buddy line as well and your set !

5.0 out of 5 stars Best anchor I have ever owned
Verified PurchaseThe media could not be loaded.
In the video above is my pontoon during a fast moving thunderstorm. This was the first true test of the system.
Previously I had a 50lb dumbell tied to anchor chain and rope. The weight would hold the boat just fine but in a storm or heavy wave situation the boat would drag the anchor slightly. I have had sand anchors, drift anchors, mushroom anchors d homemade anchors. This is byfar the best anchor I have had.
At this campsite the water is about 12"deep when you step off land and drops significantly as you go out with a mix of rocks, some sand but mostly fine silt. This area is on a point and the land is erosion protected by rocks and wrapped fencing so you have to make sure the anchor hold you off about 2' or your boat will be destroyed by waves pushing it I to the rocks.
You can see in the video that this anchor held strong. I would give 6 stars if it was an option. Folds up for easy storage and is very easy to set up and set the anchor point. It really doesn't matter how you throw off the boat because it will correct itself and dig in quickly. Removing the anchor is easy as well.
If you have a pontoon or any kind of boat that's heavy and needs a better anchor system do yourself a favor and buy this system. You will not regret it.

5.0 out of 5 stars Works as promised
Verified PurchaseWhat can I say other than this anchor works great as an anchor. I have a 25’ pontoon that we like to take out on the lake and anchor and swim. This anchor is easy to deploy and it holds great. For storage it just folds up and fits under one of the seats. Great product.

5.0 out of 5 stars Grabs easily!!
Verified PurchaseSeems to work great, used once but sets a lot quicker than my traditional anchor. I think I will still need my chain but so far I’m impressed. Only complaint is storage. It’s bulky and I will have to make a fixture to secure in anchor box. Wish it came with a rubber case.
Seems to be well built and durable though, 9/10
