It was kind of a sand/mud bottom...typical for Block Island. The Chart says ''sft'' (soft)in the middle, but where I was I saw some lighter colored sand. I recall having to use my anchor washdown a bit the clean off the anchor. It was no problem at all to get the anchor up, the spade is like a delta/bruce anchor with a solid shaft and when you are directly over the anchor it pops right out.....if the anchor dragged at all it wasn''t by much....maybe a few feet or so. And it probably swung around 180 deg from the thunderstorm that went through to clear out the fog that was there.
