If you are going to move the object to the anchor I would put enough air in the bag to offset most of the weight but still be slightly negative and then swim the object to the anchor. It would probably be easier though to just move the anchor to the object. The thing you want to avoid in any type of lift is getting too much air into the bag and have it take off to the surface too fast for you to compensate. This is the most common mistake most people make and is usually caused by underestimating the amount of lift needed to break the suction on an object that is partially buried. The object in this example is also a little larger then your first example and may now be too big for you to lift into the kayak once you get it to the surface. For something like this you should also get a paddle float so you can rig your paddle as an outrigger making the kayak stable enough to lift objects into the kayak.
