That is pretty unique. Where was this taken? Looks like Central Europe....

Only the Germans would take the time to engineer something like this.

Can you imagine the weight that thing holds!!!

Does the boat add to the weight?

I wouldn't think so.
The weight of the boat is going to displace an equal amount of water - I think.
Where's Nick? He'll be able to clear up that question.

Both are cool, but that river lift is insane! Probably took at least 2 or 3 days to engineer!

That is correct!

I would think that the boats actually reduce the weight on the pillars. Aren't the boats displacing water away from the bridge, while not adding weight themselves?

I'm thinking that it doesn't, a boat displaces water equal to it's weight and the lock picks up a constant level of water so there should be no change in the weight.
But I could be wrong again.

Weight should be the same with or without boats.
Quoted from "How Stuff Works"
An object in a fluid experiences an upward force equal to the weight of the fluid displaced by the object. So if a boat weighs 1,000 pounds (or kilograms), it will sink into the water until it has displaced 1,000 pounds (or kilograms) of water. Provided that the boat displaces 1,000 pounds of water before the whole thing is submerged, the boat floats.

No.
Ask yourself this.. A semitruck trailer full of birds sitting on the bed of the truck. Truck hits a bump and all birds go into flight within the truck. Does the truck all of a sudden weigh less?
