I wanted to add some bungee to the bow of my Hobie Revolution mainly to have a place to easily store the mirage drive when I needed to pull it for whatever reason. I didn't want to rely on putting it in the rear well since that space is now usually taken up by the livewell and also I didn't want to chance dropping the drive while moving it behind me. By storing it on the bow, I wouldn't even need to unclip the leash. The bungee also creates a very handy temporary place to stow my paddle. I just shove one blade under the cords and my paddle is held right where I can easily grab it again.

The design is really simple: six bungee hooks, six pop-rivets, and a length of bungee. I used hooks for the whole thing since I didn't want to have to use other parts and also because I like the idea of being able to temporarily remove the bungee. I could also use this bungee system to hold onto my kill bag, but I haven't really tried to use it that way yet.

How it looks when set for normal use. In this position, the bungee is fairly loose and isn't really stretched at all.

This tightens the bungee a little to the point where it makes the bow hatch a little more secure. I use it this way when going through surf. 

Here it is with the drive stowed. The bungee is pretty taut and drive is well secured and doesn't wiggle much at all. This also provides a bonus of making the hatch REALLY water tight.

Bungee in the wrapped up position when not in use so the hatch can easily be opened.

If you use pop-rivets to mount the bungee hooks, make sure there are no sharp edges on them after installing them. Sharp edges will obviously screw up the bungee chord.
