I wondered if anyone here had experience with portage carts and canoes. Not too much recent when I searched here except maybe
2018 thread

and that led to an older model from Seattle Sports and outside BWCA.COM (horrified?) I found these:

nemo-extremo

Light weight, airless, simple, in the middle price wise.

Multiple mile portages seem not uncommon around this part of the world and these won't work everywhere but some on roads etc. - should make it easy.

Primarily SR Tranquility, for now at least.

I have a nice rugged one that can be completely disassembled for storage in a kayak hull but I'll have to take a pic of it. Can't seem to find it listed anywhere online doing a quick search for 'canoe carts'.
Otherwise, I like the high clearance on the one linked in the 2018 thread. (Seattle Sports Paddleboy ATC All-Terrain Center Kayak and Canoe Dolly Carrier Cart)
Seems like fat tires are the trend on most models. Probably ideal for mud or snow but I still prefer narrow, spoked tires.

Two things I don't like about that nemo extremo. First it says the frame is anodized. That suggests that the frame is made from hollow aluminum tubing. If any of the tubes bend you have a useless cart. Second the wheels are just hanging off the end...they are not supported on both sides, so the axles can bind and will not roll as freely as wheels supported on both sides. It even looks like the cart is sagging with the wheels tilting a bit in one of the pics with the red kayak on it. It's possible that it's an OK cart but personally I'd avoid it. The one I have that's shown on your link weighs 28 pounds but at least the steel frame isn't going to bend or break. It's made in China which doesn't thrill me. The axles are just bolts with metal sleeves and work well enough but I'd still prefer an older one that had real bicycle wheels with super low friction axles. You might look for a used one like the one in my pics...they turn up fairly regularly but of course not when you need one. Mine has airless tires but personally I think the older ones with real inflatable tires are better. All that said I think you'd be fine if you got a new one just like mine...it's strong and it works.

I think Spring Creek makes a strong cart and I've also seen another super heavy duty cart for around 300-350, maybe in the Piragis catalog.

Thank you.

28 pounds is just too much to carry when the portage is not cart friendly.

Pneumatic tires have appeal but then I have to carry repair kit for them.

More thinking......

Thank you. They don't give weight of cart. I'll call.

This one has worked well for me...
Deluxe Center Cart

The pneumatic tires should not be a concern. I haven't repumped mine in two years.

This is the cart i have had for a few years now. I do need new wheels but it's been a trouble-free 8 years of use. Designed more friendly for V-hulls than flat bottoms but strap hold my flat-bottomed sit-on-top kayaks well enough. Easy to add an additional strap.

I have the paddle cart listed at $150.

Looks stable, not bad @10 pounds, but my Tranq is very flat bottom. I feel like my canoe might sit at a 45.....
Pneumatic tires, yes?

Yes. They held up until the last couple of years.
For canoes, I place it close the stern-end of the canoe till nested in the "v" then cinch strap tight. Of course, the arms bear brunt of the load than if the cart was centered.
What if you placed two straps, or affix webbing, across t-bars so the flat bottom has support? I had considered having a 2"x 3/8" aluminum bar welded across the 't-handles' but that would mess with the easy disassembly just a bit.

That's a nice looking cart design. It looks like those bars are around 24 inches apart or a bit more, and maybe 2 feet long. If the bottom of your Tranquility is wide enough (in the middle of the boat) to sit on top of those bars it might be a very good choice. Or maybe add a couple of webbed straps as mentioned if you think your boat is narrow enough to go down into the vee. For long portages I think it's important that you can center the boat so all the weight is on the cart. I had a cart with wheels that were towards the end of the boat and even with a light load it was a lot of work to do my half mile portage since I had to carry much of the weight of the boat and gear in one hand as well as pull the boat and cart along. If you may go "miles" you want the boat centered on the cart so the cart takes the weight.

...or a padded sling, with loops on each end that slip onto t-handles, could be made by someone handy with a sewing machine.

FWIW

The Spring Creeks weights:
12" Portage Cart: 12lbs
16" Portage Cart: 20.5lbs

The Seattle Deluxe Center Cart is 10.28 pounds.

what about the do it yourself one made from Kee Klamp parts?

The diy I found are PVC pipe based.

Did stumble on this comparison review of 5.

Reviee

I can't portage my canoe anymore but there are some lakes in the SNF I could
work my way into with a cart like this.
the web site with the detailed instructions is no longer up.
any help would be great.

So I'm down to these - Seattle Sport and Suspenz leading; Wike interesting and lighter but worry about pneumatic tires and light load capacity; and wonder if Oak orchard is a rebranded Seattle sport or Suspenz. Any last minute thoughts or advice?
