SCUPPER FAILURE

[Harold Scoggins]

This is why I'll never use a "scupper" cart. Fast forward video to 17:14 to see damage. Even on a Hobie, if the cart isn't properly installed you can damage the scuppers.

Those scuppers are seriously beat to hell.  Not sure that boat was designed to be carried by the scupper holes.

I could be wrong, but I think Hobie is the only yak designed to be carried by the scuppers. And I’ve seen them fail, too. The risk just isn’t worth it for any boat.

I don't get why you would want to use the scuppers anyways.  Seems like it would be more of a pain to put the cart on there to me anyways.  Same for those boonedox landing gears that everyone loves.  A lot of stress on those plates in a small area.  I'll stick to my C tug.....

Same here. Easy take down and set-up, stores inside the hatch with room to spare.

The Boonedox system is great... if you have a kayak that can support it. 

 

And honestly, it probably wouldn’t be hard for a kayak manufacturer to make them factory ready for them. But these companies are so proprietary- if it’s not their’s, or their design, they don’t want it near their kayak. Look at FeelFree and their useless track system.

I use the cart for my Hobie Compass, but I'm not going far, or over any kind of rough terrain.  I also don't carry a ton of gear, and that weight is pretty much centered over the cart anyway.  I've looked at the cart scuppers, and they're reinforced.  There's also so much flotation inside that if there was a crack, the boat wouldn't sink.  Seems like Hobie figured a few things out that others haven't yet.

 

That all said, I can't think of a better cart for non scupper use than a C-Tug.  They just work.

Plenty of companies doing things like standardized gear tracks, PowerPro Micro mounts, and Torqeedo mounting kits, universal transducer mounts.

I have a Slayer 10 and honestly the C-Tug isn't great for it.  It's about as hard to get seated under the boat as my old scupper cart was and it far fussier in challenging conditions.  This year I am going to add some eyes to the sides of my yak and mount some bungees to the C-Tug to see if I can make it easier to get it seated in the water.  I still use the scupper cart on for my loaner yak and at a lot of launches it's a ton faster then the Tug.  

 

I have access to an aluminum welder and might try to dream up some better cart design.

Maybe I've used mine so much it has become quite easy to secure under the yak. I just set mine at an angle from the yak, then lift the rear and swing over on top of the C-Tug. Easy peasy for me.

After installing the Boonedox on my PA12 I did the math on the force per square inch on the hull, based on the plate area and boat weight. I can't remember the figure but it ended up being so small it wasn't worth worrying about.

On land it isn’t too bad but trying to get it mounted in the water is very frustrating.  My yak is so wide and flat that the C-Tug’s “flaps” have to be almost flat which makes it really unstable.

i may be ignorant on how the boonedox works but i thought the pressure wasn't on the hull but on the plates which are underneath the top side of the boat and the weight is then pulling up on the topside.  I know i have seen some pictures of cracked boats before depending on the mounting location and the weight of the boat itself.

I leave my C-Tug at the water edge and then lift the rear up on the cart. Have you tried placing the cart under the bow where you have some hull geometry to work with?

It does work better if I put the cart on the bow but it's too hard to keep it balanced pulling from the wider and heavier stern.  The issue I run into is that I am trying to load and unload my yak with all my gear on board, including the heavy peddle drive.  I suppose I could unload everything, mount the yak on the cart, then reload it all and pull it to my car, but I have grand dreams of floating the yak onto a cart, strapping it in, and pulling it away. 

 

The idea I am toying with would involve making two thin aluminum brackets that attaches to the stern via a bunch of well-nuts.  Attached to this will be some kind of mechanism that lets me quickly attach two wheels, likely the C-Tug ones, and then just lift from the bow and roll it away.  The challenges will be in getting a solid mounting to the yak and keeping it all tidy enough to not snag on grass and pads when I am fishing all up in cover.

Sounds like a plan @fishwizzard, time to fire up that welder.

Largely correct, but the plates just transfer the load to the hull. The plates are mounted under the top of the hull and with the wheels deployed and the boat on the ground, the entire system pulls the plates upward against the interior topside of the hull, transferring pressure from the plates to the hull. So ultimately, those few square inches of hull need to withstand however many psi. Successor or failure depends on (as you mentioned) mounting location and weight of the boat - and also hull thickness.
