I've waterski'd behind a bombard 380 & a 25hp yam I was about 12.5 stone at the time
Id say you shouldnt have any problem with your 30hp

Great fun draging kids around on anything that floats

Kneeboards ar probably the easiest after ringos & kids love em

Im sure you will have fun whatever toys you buy

Although the towing method is excellent, keep in mind that you could be pulling off both ring fabric that holds them onto patch if happens being fabricated with thin fabric while towing a heavy load.

Happy Boating

The shock loads from towing a tube/ringo can be extreme. More than you can probably realize without seeing it in person. They can break ropes easily. My point is that you need to be careful how you use them, and try not to shock load the rope/boat/tube.

Even a wakeboarder can produce around 800#'s of force. I know I sent a non stretch spectra 80ft line straight into the boat with a lot of force. Fortunately the handle was caught by someone watching, without hitting any one.

With kids the forces are minimal. An adult can pull a SIB almost in circles while wakeboarding. I can drag mine all over the place, then again I can change the direction of a comp boat. It requires full throttle just to keep it near 20mph, and I prefer to ride at 24.2mph as that is when my board comes alive. Kids won't need as much speed, so less horsepower is probably okay.

For tubes/ringos, use a stretchy rope to lessen shock loads, since the tube will not fly into the boat. For wakeboarding and kneeboarding use a non stretch rope as it will keep it from flying into the boat.

I made my own tow harness using a piece of spectra line, some stainless links, and a float. My boat also has some stainless eye bolts, although I believe most Zodiacs come with galvanized eye bolts.

I've towed a ringo behind my old caribe 4m with a 30hp mariner - worked fine two up.

My bombard with 18hp managed to plane towing a ringo, but was definitely affected by the rings momentum a lot more - the tail was wagging the dog a lot more than I expected. It was still fun , but a lot more work to ensure a fun, safe tow. I don't think more power would have helped a great deal- the aerotec is just so light even with moderate loading and two up that the forces generated in turns were non-negligible.

As long as you take care about your attaching of the tow line and take it easy I don't see a problem with your rig, but go easy until you know how it's going to handle.

Thanks guys. It all sounds very exciting. All the advice is pretty positive. I will definitely give it a go this year.
One thing I would like to ask is when you guys refer to pulling the back all over the place, is that just very unnerving or is it dangerous. I cant really imagine what it must feel like. Does it pull the boat off the plane or just change its direction?
Being an ally deck quicksilver it does weigh in at 115kg, engine 52kg, plus transom wheels, extra seat etc so it is a lot heavier than a bombard.
Any advice on a knee board?

Just keep that Quicksilver well tube and keel top inflated, go for a spin as suggested, assume a knee board has less drag under board than a ringo, so must be easier to plane faster with less throttle than full wot.

Happy Boating

It's definitely true that a well bonded transom can handle the loads applied when towing recreational skiers. I have a Zodiac Futura with a 40 hp outboard and it easily pulls full size adults wakeboarding and foiling. A single slalom ski is a really tough proposition and my boat just doesn't make that worthwhile.

Tubes and other inflatables should always be towed from the transom, but it is possible to tow from a low pole as is shown in the second pic. I was surprised at how stable the inflatable is when towing.

Have fun out there!

Thanks. What is that in the second picture? It looks like a hydrofoiling seat? Is a zodiac futura hard bottomed, what size is it? Great pics

Kelson; You have more info on your ski pole? I assume it's gotta be bolted in; is it fairly easily removable?

Not looking for one, just curious.
