IMO, a better method is to set your stern anchor first, then as you let out stern anchor rode drive the boat to where you want to drop the bow anchor, then back down on the bow anchor to set it. You should end up roughly halfway between your anchors with scope dependent on depth. Everyone stays nice and dry.
The fortress aluminum anchor is too light to stay dug in under any challenging conditions. An anchor must have a decent amount of weight to be effective.
Not really, but it's a common misconception. Fortress is good in sand and certain mud, not so much in grass or hard bottoms. It's typically much bigger than your main anchor, because it's lighter, you can take a larger size. Many boaters use it as a storm anchor by oversizing it. It's the width of the flukes that creates the holding power. If you truly think weight is the main component, try a mushroom anchor of 40kg with a 15 ton boat
