Saturday, I went out with some friends on Lake Washington. We didn't end up very far, because a boat had sank over night in the marina. We floated near the action to watch them bring the boat back to the surface.
The back of the boat was resting on the bottom of the lake, so all you saw from shore was the bow of the boat.
As we floated and watched this happening, we began taking bets on the boat length and brand
Starting to emerge, but still filled with lots of water. This is when they began pumping the water from the inside to help get it above water level.
Those inflated bags helped get this boat out from the bottom of the lake. Later we all went to the wine tasting event in the marina "Kirkland Uncorked" and heard that it cost $3,000 to pull this boat out of the water...wow!
