Has anyone made their own course? I have looked a little at it and doesn't seem too difficult, but it's always the details that get you. Still trying to balance buying one or making one. Looks like $500-$800 to buy one and probably $300 to make one. Looks like traditional centerline system is easiest to make.

Where I am at would have to drop in quickly, ski and then pull back out when I leave.

I can understand making one, but how do you go about constructing the mainline? I mean you need those diamond shaped cable rigs to hook it to the PVC pipes. How do you do the diamonds?

I made one. Bought 900 feet of rope and measured off the lengths. Initially used a long section of PVC to line up the gates and turn balls at the premeasured points. I was using individual anchors so I could just clip the buoys and go.

In the end, I ended up with a bend in the course. I then got a 200 some odd foot strand of rope and marked the distances on it. With two people in the water and one person in a john boat helping us align the buoys by sight, we got it lined up. We then lined up our turn balls by sight. We remeasured the distances between all the balls and got it accurate down to the inch. Added magnets later. Skis great and gets good times.

On the mainline, if you use rope in shallow water, make sure you get something that doesn't float or that's low stretch. The tension to keep 900 feet of rope submerged is pretty great.

Our course works great for us. If you're planning to remove it, look for a used portable course.

Or, you can go to www.wakesiderides.com and look for the how to build your own slalom course "how to." It used to be on the malibu board, so I think that's where it is now.

Just buy Farmer's, I'll make you a good deal on it! ;)

I made one years ago. Not sure it's worth it though. The expense of the materials ended up not being much less than buying a pre-made course, not to mention the time involved in designing and constructing the course. Case in point: After my home-made course was stolen, I bought a used course for about the same amount.

BTW, if I don't find some locals to ski with around here soon, or find a permanent course my wife can pull me through, I may just give up skiing and sell my portable course... stay tuned. ;) The wife wants a Carolina Skiff! :eek:

Yeah, those could be some of the details.....any hints! I really need to see a real course.


I think I can put a PVC T fitting at the point where the two drive buoys go up, that spreads the diamond out, then you run the main rope through one end and another piece of rope through the other end and attach the ropes at each end.

Great inputs, thanks Doug! I was hoping to align on a football field or something like that. Pretty amazing the distances! I like building stuff like this and may be able to get a friend to go in with.

OK Brad, I'm almost afraid to ask, what's the deal?

DOn't give up Shepherd!

Doug; Do you have start buoys on each end? Looks like that takes the rope length up to ~1200 feet.

No 55m gates yet. Just haven't gotten around to it. Perhaps a good project for the Spring. Again, if I had it to do over again, I'd probably just use one 200' section of rope and measure things out that way, aligning by site. The only reason to have a 900' (or 1200') strand of rope (in my situation at least) is to leave it in there so you can find everything faster. Right now, we have a reference line to one boat guide and used the measured rope to find the rest of the boat guides. As for the rest of the anchors, I can just hop around in the mud until I find them.

man eastie, why dont you just spray paint some of those lillipads orange and ski around those??? 8p ;) that seem a whole lot easier than putting a course in.... :dance:

Leroy, I have an Insta slalom with a rope mainline, and the mini coure buoys.

Let me know if you need pictures, measurements or what ever. I've seen pictures of what you can do with PVC and a portable course would be a walk in the park!

Question for those of you with portable slalom course experience, how do the pvc booms collapse w/o having slop in the pipe size, I've never seen pvc that is od=id perfectly, so do you buy the coupler and hollow out till the smaller one can pass through??

I was thinking of building my own w/o plans but want a good idea about this part.

I got this a year of so ago, but it has all the parts you need and an estimated cost (might be outdated). I also have some word documents that might help, but they're too large to attach, so email me if you want them. THE FORMAT GOT ALL MESSED UP and ITS IN EXCEL WHICH I CAN"T ATTACH.

Here's a web site that has some listed, but they may be sold?
Good luck!

Farmer; Thanks! Since you offer, I would like a picture of the diamond and where the PVC attaches on each side and the winch set up (assuming you are using two anchors), and the PVC sections (think I can just use bungie rope through them like tent poles?)

They use special thin-walled 1 1/2 pipe so that regular 1 1/4 will fit perfectly inside it. It is called schedule 40 pipe I believe. The regular 1 1/2 that you buy at a hardware store won't work with 1 1/4. You can tell the difference by looking at the PSI rating. Regular is rated for 330 PSI, the thin walled is 200 PSI. I need to replace a couple of mine that a broken and can't find the thin stuff.

Just a little FYI on the tent pole idea, If you do this, you are going to double the amount of PVC tubes that you have to carry/store, since they don't collapse inside of each other. My insta-slalom has basically 2 bundles of ten poles (with one collapsed inside of each). If all of your pipes are the same, you will have 40 seperate pipes to put in your boat, and store in your garage. Just my 2 cents.

I'll dig it out of the shed this weekend, the rope is reeled up on a hose reel from Home Depot. The main line has two quick release clamps that just snap on the anchor.

unless it's a project for fun, dont do it. just buy one from ez-slalom ready to go. i found it hard to find all the parts needed . had to go to alot of stores. i think i ended up spending more . i could not find enough bungee or tubing anywhere local. i guess if youre patient and order thhe parts it may be cheaper.

Thanks Farmer.

On the PVC, great input, I admit I haven't completely thought through it, but was thinking from far boat ball to ski ball is total ~40 feet so that would be four 10 foot pieces and with 6 balls there is 24 pieces. I do like finding pipe that will slide inside, that is very smart and then only 12 pieces!

That's nothing. We have to go out there with the aquatic weed rake once a month to keep the course clear. Makes for good camoflauge otherwise though.

I got 100 ft of the 3/8" latex tubing cut in 10' strands on ebay for $10. Not a better deal out there. Plenty for all of my buoys

Have you ever hooked some seaweed on your slalom fin and wing?
I have a few times and it throws the ski way out of control. The usual result, if you are in the course or sking agressively, is a major crash and burn.

Because the lake is so low, there is some moss buildup at the south end of the course. I have been dragged down by it once in a turn-around when the boat slowed too much. The moss is not an issue in the course where the water depth is greater. As for lily pads, they are easily removed. It does take a bit of time without herbicides. As for skiing over them, from what I've seen, the ski rips them to shreds. All the same, we remove them so they are not an issue. That picture is a pre-removal picture.

that is a good deal, i used all bungee for mine since i couldnt find the tubing locally. cost me a fortune since i ran out all the hardware store nearby and had to buy the thick stuff.

I built one of these a few years ago. Wasn't difficult. Check out their site, they have several options.

The kit from E-Z Slalom is great. It gave a materials list and directions to assemble the pvc arms. I had to go to a whole sale place because the guys at Home Depot didn't know what I was asking for. I guess the pipe goes by different names around the country.
The mainline was assembled and ready to go. It took about 10 hours or so for my brother and I to build it. I would do it again. Just be patient and follow the directions.
