With the CD 22 we always put out a bow anchor(we have never had it hang up), and put the stern on the beach--or just off the beach, with the two anchors (one on each side to keep the stern in the same place and allow us and the dogs to get onto the beach via our "pet step". Only once did we have enough wind to drag an anchor or have to move. We have spent about 30 nights at Lake Powell--far less than many other C brats--but have covered almost all of the lake. However, each year is different because the water level varies.
Not sure if we will get the TC 255 to Powell this year--but if so, we will have to experiment to see if we go bow or stern to the beach--and will take the pet step off the Armstrong bracket.
