i picked up a kayak yesterday

There is no question the wheeleez works great in soft sand due to the extra wide tires, however the downside is the vinyl tires are easily damaged by sharp rocks, glass, etc.....and if you over inflate them, the valve body will separate from the vinyl....unless you have a low pressure tire gauge, guessing at 2-4 psi is a crap shoot.
On the other hand, the C-tug can run at reduced tire pressure to improve operation in soft sand.
I started out with the "Hobie wheeleez cart" for my Outback and had issues with the durability of the tires as I rarely encounter soft sand.....I bought the C-tug and it is a better solution for my use........I can run over sharp rocks and uneven terrain w/o any issues.

Ahhhhhhhh.......I have been keeping my C-tug's tires at 30 psi.  Will definitely try the reduced pressure idea.  Never even occured to me.  DOH!!!!!!!!!

 

The old Wheeleez were made of the soft vinyl, but the new ones like the ones I posted are tough polyurethane that can be repaired with a soldering iron if ever punctured.  I even received repair material with my smaller set for my Hobie. 
I've pulled mine over some nasty rocks fully loaded (100+ lbs) with no concern of a flat.

C-Tug has it's place, it's cheap, easy to see, easy to store, but it's frustrating to assemble then breakdown the first few times. Think i described it in an older post as a frustrating origami project Machiavelli would be proud of... 

LOL WR......funny you brought that up.  The very first time I took the T-13 out on the canal I could not for the life of me remember how to break the C-tug down and wound up carrying it back to the rig.  I wound up reviewing their video on how to do it and had to laugh.  It takes all of about 20 seconds or less to take it to parade rest.  I like it and am sticking with it.  As demonick recommends, just won't put in on mushy shores....

yeh, being prudent about the place its used is key. probably for most launches i do on those rare times i can get out, it works fine. considering it's cost and portability vs. it's competitors, it's actually a bargain.

word of advice to anyone who does buy and use the C-Tug; practice assembly and disassembly using the updated video. the hardest part is actually getting the two cross beams to mate properly. If you don't, you end up posting comments about how frustrating it is to use.

WR you couldn't be more right.  My first launch was at Shine Tidelands SP on the West side of the HC Bridge.  A firm beach that was no problem for the C-tug....BUT......so many razor sharp barnacles I wound up spending a lot of time "grooming" my hull when I got back home.  I would have used the ramp had not a couple Yahoos decided to park there and block it.

Next was Twanoh State Park on the beach next to the ramp.  THAT was the soft beach that the C-tug could not handle.  I'm still trying to learn the area to find the best (AND the worst) places to put in at.

Cheers.
