Yes, agree, it is a science....I really like the Delta. Looks good, and design wise, seems it is perfect. I just could not figure out what I was doing wrong.
I recall in the inlet area a few years back in 30' of water anchoring down for cobia fishing. I could not get the anchor to stick quickly. It dragged a bit then grabbed. Must have been doing what they show in the video. Then the tide changed and again, started dragging and before I realized it I was almost into another boat.
Then when offshore in 100'ish, same issue.
So thinking in the inlet, shifting soft sand, but again, they keep it dredged so not sure if there is a layer of soft sand and deeper is the hard sand. But offshore, who knows.....
Seems the Delta has to be able to turn upright before it can dig in from what I can tell in the video. Something needs to catch that point so it can start digging.
