We’ve probably all seen scuba divers on television, hitching rides on the backs of manta rays or sea turtles. For those of us who love the ocean, it looks like a near-magical experience, but ... you shouldn’t do it. Marine biologists will tell you that it’s simply a form of harassment, which the animals themselves don’t particularly enjoy. So, how can you replicate that “flying underwater” experience? Well, Norwegian inventor Simon Sivertsen would suggest you buy his boat-towed Subwing.

The device consists of two hydrodynamic wings, joined in the center with a steel-and-rubber swivel – this allows them to pivot independently of one another. Riders hang on using rubber grips at the front of the wings, or by grasping a rubber grab loop in the rear. Heavy-duty Dyneema fiber ropes are attached to the top surface of both wings, and join up with the user’s own tow rope.

Once they’re in motion, riders can steer the Subwing up and down, left and right, or perform spins, by angling or twisting the wings. As can be seen in the video at the bottom of the page, it looks like a lot of fun, although the device is recommended for skin divers only. Presumably the sudden depth changes involved could make breathing compressed air dangerous, plus the tanks would no doubt create a lot of drag.

Additionally, towing speeds over two knots aren’t recommended.

Speaking of danger, one does have to wonder how the people in the boat will know if their underwater buddy has been shaken off of the Subwing, or cracked their head on a piece of coral – it’s not like they’re able to see them, except for when they pop to the surface to grab a breath.

In any case, for people willing to take the risks, the Subwing is available in three versions. The fiberglass model sells for US$700, the carbon fiber matte model goes for $850, while the carbon gloss will set you back $895.

This thing looks like a blast. Make a cheaper plastic version for $300 and I'm sold.

This is an awesome idea I want to try it for sure.

What !!! I was doing this 5 years ago when I worked on yachts as a liveing. All we used was the washbourds ( removable , sliding door ) of the yacht and a 50 ' mooring line. It worked fine and it was free . What is the nest thing that is going to be re done that is all ready free on a boat? Bilge bording . Wiith a $300 price tag. Nice try all the same but far to costly when it is free or other wise a small bit of plywood and rope works v well. Simon

Shark bait!

I like it.
Two suggestions: 1) There does need to be an alarm so that the boat driver can stop if the diver lets go. Since the towline tension will decrease radically when the diver lets go, a fairly simple mechanical "flag" could pop up when towline tension decreases. Fancier audible alarms would be even better and enable this thing to be fairly safe.
2) Since there's a towline from the surface, it wouldn't be too hard to have a flexible air-suply tube running down to an air-mask. That would enable the diver to stay down having fun indefinitely : )

Looks like a fast way to tear up a coral reef. Not all ideas are good ideas. Murphy's law dictates that if something bad can happen then it will.

Just use a water skiing tow rope and swim fins.

great concept...but its already been done...we had something similar growning up as kids...and that was over 45yrs ago...Im sure that this is much more technical than our fun ole porpoise board...that our uncle made for us out of a block of wood...with 2 handles ..retro is new...Im guessing...but using this with the liquid image underwater googgles would give some great footage...

Ummmmmm - going a bit mad here.... ancient memories.
There was a movie about sponge divers from Greece in an OLD black and White movie.....
On a set of steel rods with control surfaces - being towed behind a boat... something like the front end of a U boat - minus the U Boat.
I think it was either this one, or the following.

Hmmm. I'm 54 now and was doing that when I was a teenager, with two bits of wood. You'd have to be dumb to pay that kind of money.
To Denis Klanac in an earlier thread, You'd have to be pretty dumb to be any where near sharks if your doing this.
