Handle for maravia cat tubes
I recently acquired a pair ( I hear they work better in pairs) of Maravia 16'x24" maravia cat tubes. I am in the process of outfitting my new boat and it came to my attention, that these tubes have no handles. I assume that this is the case for all Maravia tubes, but maybe not.
Anyhow so this was my solution and I wanted to get some feedback from you guys before I get this thing on the water and find that I have made my own death trap.
I started with 6" sections of 3/4" alum pipe (it's a little over 1" O.D.).
I then drilled 1/4" hole in the middle of the pipe, and fed a piece of rope through. I tied a figure 8 knot to function as a stopper knot inside the pipe.
I then tied the other end of the rope in a figure 8 loop around each one of the 8 D-rings on the outside of my tubes. I made sure you keep all the loops small so you can't get your hand, or anything inside the loops. I sanded the tube down so there are no sharp edges. What do you guys think? Is it ok to leave these attached to outside of the boat? Do they create any sort of safety risk that I am missing? Let me know what you think.
