Was just out on the lake with a group of people. I wasn't sure of the sand we'd be in and I didn't want to have my boat tossed by the waves onto the shore and the bottom getting damaged by rocks. I do have a rubberized Danforth anchor on the boat, but was struggling with it being able to hold without pushing my boat towards shore, since it barely holds in deeper water. I brought my box anchor with me, connected to a bungie style rope, that I would attach to the front of the boat's trailer winch point. That box anchor was able to hold my boat in place and as the waves started getting stronger, the anchor held tight and kept pulling my boat back out. Never had to worry about my boat bottoming out or drifting. I also used a Slide Anchor Shore Spike, with a Danik Hook, and had the other end attached it to the back of the boat. This was done just to pull the boat towards shore when loading people in and to ensure the boat stayed still and not bump into other boats.
Depending upon conditions, wouldn't recommend anchoring at 2 points, but I was at a lake, so not much worry there. At the ocean, the box anchor would hold up really well. I actually got these anchors from the previous owner, who loved to beach the boat all the time. He absolutely loved this anchor and can't disagree. Really put my mind at ease knowing my boat wouldn't bottom out or drift, especially while watching mastercraft boats drifting and owners resorting to using their prop to help keep the boat still.
