I have an issue I'm not familiar with. I am used to sailing in bays and the gulf, but I'm now in a man-made lake. I have nearly lost my Danforth anchor several times when it became entangled with a submerged tree. (The bottom otherwise is heavy clay or rock.) There can be some pretty stiff winds and surprisingly heavy seas when staying overnight, so just a straight weight anchor won't do. Is there a better anchor type for this situation? Is there a better way to handle such a tangle than hoping the branch will finally break off and free the anchor? (Sometimes it is too deep for me to want to dive for.)
