The Eddy Kite

Some History & Personal Experience

Firstly, what exactly is an Eddy kite? The original design was a large diamond-shaped kite from the 1800s which flew without a tail.

Unlike the historical Eddy, most retail Diamonds these days are tailed. Most also have some dihedral or bow in the horizontal spar. This greatly helps stability and enables the use of shorter tails.

This little list sums up the history of the Eddy...

• Invented by William A. Eddy in the 1890s, and inspired by ancient Javanese bowed kites. More commonly known as the 'Malay'.
• Diamond shaped, as already mentioned, using spruce spars.
• Sail edges attached to wire perimeter lines.
• Bowed horizontal spar, attached to the vertical spar 19% of the way down from the nose.
• Loose-fitting cotton sail which billowed at the tail end, forming a small keel.
• No tail. Very handy for kite trains, since tails tend to get wrapped around the flying line!
• 2-point bridle, one point being where the spars cross, the other at the extreme tail end.

Our MBK Dowel Series of kites are all tail-less, like the Eddy-inspired Dowel Diamond. That's an old version of it in the first photo on this page.

However, we have made some minor changes in a later version. They both fly beautifully in very light wind.

I remember on one occasion in the late afternoon, this kite floated right up to 400 feet, going almost overhead. At the time, there was barely a breath of wind at ground level!

In case you are curious about Eddy himself, here's a few interesting details...

His full name was William A. Eddy.

• He was from New Jersey, U.S.A., and worked as a journalist
• Eddy developed his efficient, stable, diamond-shaped kite in the 1890's.
• He began his kite flying with the classic American Barn-Door design. Hexagonal kites that sometimes had a coffin-like shape.
• Eddy was inspired by the tail-less bowed Malay design, since his kite-trains kept getting into trouble with tangled tails!
• Eddy was famous for his kite-powered aerial photography and also meteorological experiments. These were carried out at Blue Hill Observatory, near Boston, U.S.A.

In some circles, the term Eddy is used more loosely to mean just about any kind of Diamond kite. I first became aware of this when a European blogger featured my 1-Skewer Diamond design in a post. A 'little Eddy' he called it!

Why Make An Eddy Kite?

For a start, you won't find many truly Eddy-like designs in the shops. Tailed Diamonds are the closest thing offered both on and off-line. However, a good reason to make one is that the design is quite easy to build, and results in a stable, efficient kite.

For some additional fun, you can stack these kites together along one long flying line. An Eddy is a great light-to-moderate wind flier.

The Eddy kite was the inspiration for my original Dowel Diamond design, which you can see in the first photo on this page. It's hard to spot in the photo but it had a 2-leg bridle.

From a distance, the Dowel Diamond and the Eddy look very similar, but there are in fact a few differences. The Dowel kite has a plastic sail and tape edging. It's shape is quite close to Eddy's original, although the overall size is somewhat smaller. Some of the originals were almost 3 meters (9 feet) in height!

It's relaxing seeing the Dowel Diamond hang up there in a light breeze. Having a 3-leg bridle, my most recent version doesn't waggle its wing tips like an Eddy kite would do. See the photo and video below. With a sliding knot on the bridle, it can be adjusted toward the nose a little if the breeze is stronger and threatening to over-power the kite. The 1.2 meter span sail generates a decent pull, and can keep the line fairly straight even with over 100 meters let out.

Modern Versions Of The Eddy Kite

It seems Eddy kites are everywhere. Some bowed, some made with dihedral. People like to make them very colorful too, unlike yours truly who has stuck with pale orange for 3 series of 8 kites each! Going overboard with decoration can turn even an Eddy into a lumbering fresh-wind kite though...

Sizes vary a lot too, with quite small versions being made for children and other enthusiasts tackling full 9-foot replicas of the original meteorological kites!

An interesting but simple variation of the Eddy kite is the single-point bridle Diamond. The flying line simply attaches to where the spars cross. The crossing-point is 25% from the nose rather than the original 19% for these.

With sufficient bow and slightly slack sail these kites can still fly tail-less, and therefore are perfect for flying in a stack or train.

   Just prior to getting some in-flight photos, I came close to re-doing the whole kite from scratch... Going back a few steps: After printing out the spar shapes and applying most of the sticky tape on…
