Use more than one SandShark for boats over 30′

I went to the local marina today to drop off a few Sand Shark Anchors for the upcoming sale. The guys there were busy surprisingly, lots of boaters in getting service work done, mostly houseboats. One of the customers saw me struggling to carry them in and helped me out thankfully. I handed him 3 of them... he kinda grunted and gave me a look, that's about 50 pounds of steel.

We started talking and he was pretty curious, he liked the idea and design, but thought the auger blades were kind of small. He asked if I thought the anchor would hold his 40 foot houseboat on mostly a sandy bottom, off an island on the lake with a small little beach for docking. He mentioned it's a pain every time they go out, and needs to constantly watching his pvc spikes and anchor lines tied on shore to make sure they don't get pulled out. I told him two Sand Shark Anchors would hold his boat in place with no trouble, usually I recommend 1 Anchor for a 30ft boat and 1 extra anchor for every 15ft of boat after that. A lot depends on the water conditions too, but in his case it wasn't an issue.

We went out to the docking ramp near some shallow water and I let him auger one down into the clay and and sand bottom near the water on the shoreline. He flipped out the handles and cranked it down to about a foot and half pretty easily. I told him to stop there and try to pull it out. He gave it a couple big tugs, then laughed saying, "Well I doubted the auger blade size, but I probably should have known better... you seem to be selling quite a few of these and they're heavy duty. I've seen these around and never imagined they were this solid." I told him that he wasn't the first to doubt it, most people look shocked when they first hold one, commenting on the weight. I'm always more than happy in letting people try out the Sand Shark for the first time and auger it down, then try to pull it out, gets them every time!

How to keep your anchors from being pulled-out.

Put an auger anchor just into the water.  Not on the dry shore, but far enough in the water to keep the bottom of the auger covered with water.  With beach spikes in the sand, there is not a natural way to keep sand packed around the shaft, plus there is no "pull-out prevention" like an auger blade.  When an auger anchor is in the water, the water will keep the sand packed around the shaft and blade, this keeps the anchor firmly in place.

The water weight applies downward pressure onto the sand.  This creates an air tight suction which also keeps the anchor in place.  You will find that with the SandShark Anchor, you will not be pulling them out.  You will have to "unscrew" it out of the sand.  With the SandShark you have a 1" solid shaft with a 4" blade planted into the bottom.  Your kids won't be pulling that out!

Lake Michigan Testing

Did some testing this weekend at Lake Michigan near New Buffalo, MI and the SandShark passed with flying colors! Decided to set the SandShark near the beach.  It was pretty rough, waves were  3' plus.  The bottom was real sandy so I was concerned about getting a firm surface to grip into.  I set the SandShark in pretty deep, about 2 to 2 1/2' because it was so rough.  I had about a 21' boat.  The boat was barrel rolling with the front slapping up and down,  waves were turning into white caps as they were coming on the beach and  THE BOAT DIDN'T MOVE!  This anchor will keep a boat under 30' in really choppy conditions in the same place without any problem.  I am going take some videos on Lake Michigan soon and post for everyone.  Definitely want to go back there, it was our first trip there and it is BEAUTIFUL!  Thanks.
