I need a handle that floats

So my son and some friends took the boat out and in haste just looped the rope around the tow point. On a fall the handle popped and the rope got enough slack that it came off the tower. The handle sunk along with the entire rope before the rider could get to it. So there's $150 laying on the bottom of the lake. The handle was the Proline LG. We loved the handle but hated that it doubled as an anchor.

So I'm looking for a similar handle that floats. I was leaning toward the Totem or North but they be too thick and I wasn't sure if they floated. Any recommendations for a good floating handle similar to the LG. Thanks.
