I once had a homemade set that came with my formerly owned
P18-2.

It had a galvanized steel pipe for an axle.
It had standard wheelbarrow wheels; the bearings where taken out and the axle fit thru the hubs. NO bearings, just rubbed on the pipes. Held in place by hose clamps around the axle.

Did they work? Why yes they did.
Did it rust some? Why yes they did.
Where they as good as Trax? Why no.
They had some trouble in the loose sand, but they did work, and I used them fot years.

And fot craddles?
Jig saw cut pieces of PVC pipe, contact cement some carpet on them, viola!

My last boat a owned, a N6.0, came with Trax.

Didn't someone use a 55gal barrel for a wheel?

I don't think it was 55 gal. but, yeh. Actually I've seen a few examples. If you're not trailering they seem to work okay. Saw one made of pt lumber, must have weighed 500 lbs! Looked like a small deck.

I think that I saw a pic of that too! Had to weigh more than the boat.

I am a engineer and toolmaker/fabricator. I also am as cheap as they come, Dutch background. I couldn't make a pair of wheels as cheap as purchasing the Cat Trax. Wife bought them for me when we got married 20 years ago. I don't use them much and they are stored inside. I never had a problem with wheel leakage. $$ per year is cheap. Like Matt said, don't sell them with the boat, especially if you plan on getting another catamaran. I always lock them to my trailer as I know they are valuable.

When something works, the people using the product will sell the product for you.

I made a set that works great! Bill vining gave us the list of supplies. Think it came out to 200$

That being said, my boat is light (f16) and they don't work great on soft sand, but they work fine. I do, however, wish I had a set of real catrax. My tires aren't as big but the gauge of al tube I used makes them relatively heavy compared to the real trax. If my boat were the standard 400lb cat I don't think they would work

I have a Nacra 5.2 and built my own set.
I used a couple of long pressure treated garden fence posts like 5x7 cm (approx 2x3"), just pine, nothing heavy.

They are held at the right distance by shorter bits of the same wood. Then two pairs of largish wheel-barrow wheels ,Made in China (6! Euro's a piece) are fitted to a stainless tube which is recessed into the wooden spacers to either side and held there by an alu. strip and ss screws.

The redundancy means I can still move my boat, even with one or two flat tires.
This set up is not heavier than Cat trax as far as I can tell. I must admit thet Cat trax are still better on the beach though.

People have asked to borrow mine (more than once), so they must work! But I use them most on sand, mud and grass.

The caveat is, this is my second attempt, the first was waaay more expensive and both together set me back as much as a decent set of second hand cat trax would have.

If I had to start over I would fork out the cash for some second hand cat trax. If I was really strapped for cash, I'd build the above again.

Oh yeah, the boat hulls sit on the outside, the wheels are just inside the hulls. The bits that stick out (where the boat sits) are covered in el-cheapo doormat.

We used to import the EuroTrax years ago. Have been moving our warehouse and found a bunch of cradles for them. All new and with stainless steel strap and lock knob. These are the adjustable type and move easily along the axle. Fit 2" (50mm) tube axles so will fit EuroTrax, CATTRAX etc. These used to retail for $130 a pair. Final blowout price of $60 a pair plus shipping. We have the UNI, UNI Plus, V and Asymmetrical in stock.

That's a good deal.
Where are you shipping from?

I've gotten sets buying complete boat packages at the right price. Then sell off the parts or boat package and keep what you want. (TRAX) and you'll end up getting them free or even making money off other parts. I've done this several times and eventually sold the used sets and ended up put it toward a new set for 550 (with shipping).
Can't build a set that works for less. You want them to float in water, and be light enough to carry. They hold their value well and last forever if you keep them out of the UV.

nice grave dig




I used a pair of front ATV wheels from a Yamaha 225, because that's what I had laying around at the time !!!

I had to make my own hubs tho and that was the PITA bit, alloy weld a plate to a lump of solid bar then machine it into a "hub".

Took me Saturday to do the job and they've done lots of trips around the place now and so far haven't done anything wrong, I do have a modification in mind and that is to fit a better "bearing" as such, using a nylon bush is ok but there's a better way



these work really well on sealed carparks etc & even better on sand, where they fail a bit is on a beach that's covered in sea-weed, this ia probably due to the fact that they are 'inboard' of the hulls so a lump of sea-weeed tends to "rock the boat" so to speak !!
The other 'issue' is the weight, being m/cycle related, the rims are steel so they are a tad on the fat side and then there;s the long term issue of rust.....
I could get them galv-dipped but I figure a lighter set from one of those pocket 4wheelers for kids would be the ducks-nuts, they are also alloy rimmed

apologies......
don't actually have a single shot of the finished product, but you get the idea

I made a set from aluminum golf cart wheels that work just fine. Been using them all season now. I have a brand set set of cat trax as well and I haven't felt the desire to put them on the trailer instead.

They are ~10lbs heavier than the trax, but that's most because I haven't bought smooth tires for them yet.

I have one more pair of wheels that I made as well at the same time. If I did it again, I might sand cast the parts instead.
