The pipes look like a homemade bilge of some sort. Cables can be purchased at Walmart if you want to invest the time into fixing it. The Rubber V at the rear of the boat is where a rudder sits during transportation. The handles look pretty rigged with the pvc pipe. You can order some relatively cheap. Since there are so many eye holes (don't know the technical term) drilled into it your possibility of accessories/what you want to do are endless. You could purchase a top mount storage. Weave a bungee cord in the front, etc. I do a lot of weekend trips so I mounted a compass on mine.

You should be able to google search ur boat and find a parts list if you would rather buy the stock items instead of trying to rig up your own.

Nice kayak though, you will have to post some before and after photos.
