I found these. Google: Taylor dock wheels
18" for 2" axle.
Haven't ordered yet, but they look hopeful. Just looking to contribute.

One could order the replacement wheel and rig their own axle, or order with the dock mount and modify. I'll probably go for just the wheels and noodle something together. It's october 21st and I think last sunday was the last day I'll trick my girlfriend into going out, new O'neil booties or not. And that leaves me plenty of cold nights to smoke cigarettes and think/design/order/construct etc.
I just finished my mast step winch setup (electric, saves my energy) and am looking for a new pile of parts to angrily shake my fist at, kick, think about in bed, develop new ideas for, and noodle with. I need a new design to obsess over on my commute and while I lie in bed. Or when my girlfriend is telling me about how the one girl at work.....something something. What's that babe? Sorry, I was envisioning homemade cradles. No, for the boat. What were you saying?

Wish I could find a beach wench to haul my boat up the beach.....but if she was strong enough to do that, she could probably kick my butt!

Just a bump to see what the latest on Cat-Trax technology is these days....

One of my Cat-Trax tires went permanently T.U. on me here on the beach in Puerto Penasco..... Even Slime didn't work on it =(

Happy Cinco everybody!

You'd be better off getting a beach wench, she could go T.U. on you at the beach and at night too! LOOOOL!

Where is a good place to perhaps find a used set of Cat Trax?

I'm thinking dock wheels and conduit. Price at Fleet Farm is under $35 each and 1 -1/2" conduit isn't expensive. Maybe $100 all in?
I build one years ago using a single 30 gallon plastic barrel as a roller under the middle of the boat. Worked OK. I bolted on wooden ends for the conduit to ride on.

Thanks to them for saving the Web a page at the time...

I made a set of beach wheels.
I ordered Otter dock wheels from Mill's Fleet Farm. They are 24" diameter, 9" wide with a 2" axle hole. $86 for 2 including shipping. SKU # is 006364657.
Used 4 aluminum 2" shaft clamps from McMaster Carr, $56 plus shipping, and an 8' length of 2" OD aluminum tube with .25" wall thickness from Onlinemetals.com for $107 including shipping.
I put foam pipe insulation over the piping and wrapped it with duct tape, and put a rope through the pipe, going through a tennis ball at each end of the pipe. I figure the total cost was about $250. Also got 3/4" plastic plugs from Home Depot, drilled the drain holes in the wheels to 3/4", and sealed the caps in with silicone sealant to prevent water intrusion into the wheels.
Here's a link to a couple photos on Flickr: http://www.flickr.com/photos/100085529@N02/sets/72157635017809482/

It's funny, since I bought most of the options and toys for my Get: Spinnaker, wings, trap lines, marine radio, toy box, Torqeedo motor, Cheeta motor mount...but it rankled to spend $500 for Cat Trax. Although my home made ones aren't pneumatic.

I made one from the following parts list for less than $150.

2) used golf cart wheels and tires $40 (Craigslist)
6) 1-1/2" schedule 80 pvc pipe flanges $68.46 (Grainger)
1) 1-1/2" x 10' schedule 80 pvc pipe $20.94 (Grainger)
8) 1/2" x 2-1/2" Hex Bolts, Nuts, Cut Washers, Lock Washers $15 (Home Depot)

Pictures at: https://plus.google.com/u/0/photos/106762135861927301326/albums/6106948507821485057

You can get these flanges and pipe cheaper, but I liked the help at Grainger, you can do store pickup there. The 1-1/2" flanges are on a 4" bolt circle and fit the wheel lugs perfectly. Used golf cart wheels and tires can be bough for $5 but these are 10.5" wide. The 10' pipe allows me to support a wider beam catamaran. The whole thing breaks down without tools for hauling on the cat trailer.

I used a rotary rasp in a 3/8" drill to take the shoulder off the inside of the flanges and rounded them out with a rolled up 80 grit sander belt so they free spin on the pipe, the only other tool needed was a 3/4 " socket to bolt the flanges and hubs together. Just wiggle them around on the axle so they free spin well when you tighten the flanges. The 1/2" bolts are overkill but they fit snug and keep everything alighed well. You could probably use nylon 1/2" bolts just as well to save weight, but the entire assembly is not that heavy.

The only flaw is the flex in the span between the wheels causing an arch in the axle with load on the outside of the wheels; but If I keep the wheels close to the inboard of the hulls it should be fine, if not I can add stiffness inside of the axle with a 1-1/2" wooden dowel.

I havent tried it with a catameran yet but I plan on testing it as soon as I get my hobie out of storage. I'll let you know how it turns out!

I use the rear end out of lawn tractors with 18" x 8" tires on 8" rims (Up to 21" x 10"), put a 24v scooter motor, speed controller and battery. I built a frame to bolt to the rear end that holds a 8' piece of supper strut for a cross bar in front of the tires and made a handle like a wheelbarrow. I will pull the boat on from the rear until the rear crossbar sits on the handle. We can get 4-5 18's and 16's across a span of 75-100' of sand at lake Erie on one battery charge. One person can move a boat with no problem. I was going to make them to sell but I need to get $700-800 to make it worth it and most people don't want to spend that amount of money.
