believe the Spade's sharp point penetrates faster and easier, so it's
usually deeper than the Danforth would be.

Probably so, ours usually comes up with a huge mud ball on it,
probably weighing more than the anchor itself. We've got a 1 hp
generator driven high pressure wash down pump and it still takes
several minutes to clean the anchor off when it has been well dug in.
