My guess is that aluminum is considered too light... my current anchor is a fairly large but aluminum fluke, and it's surprisingly tricky to set. Also I wouldn't trust it under heavy load, especially after a wind shift; if it holds, the torque would probably bend the shank.hmm, so if stainles is so poor under these conditions what about aluminum?
Yeah but, not everything that everybody wants is actually the right thing for them to have.Perhaps just because their customers want them??
