-Wind: 10-20 knots
-Crown Beach

Conclusions:

-Bridle points need to be non-floating, for fast inflation
-Strut ends also need to be non-floating

Rok G12 – fully taped construction – test Aug 3

8/3/11

This was the first test of the new construction, which includes cubic 50mm tape inside and out and 25mm double-sided tape.

We inflated the kite to 5psi. We tested over 2.5 hours at Crown Beach, in 10-knot winds. The flight was stable, with a line angle at 45-50 degrees. We taped a GoPro to the line and used a 100m 1.6mm line.

Betsy note: bottom photos show the G12 kite seams in the shop prior to the test.

Line Cam Mount options

7/7/11

We have many variation of the line cam mount.

Joe has created quite a few

here are few more to added

Kitefoiler Test with J-foils – Jun 15

6/15/11

We tested the Kitefoiler using the original Trifoiler J-foils with the Kitefoiler extensions. We used the Tom Speer-designed T-foil rudder.

The wind was light. We used the electric winch handle to successfully winch the kite back to the boat.

Dual bar setup. Launch bar and flying bar.

Don tried out our new Zeal goggles that were equipped with GPS (https://www.zealoptics.com/transcend/). He and Jamie purchased the goggles to play with the sensor inside and to see if they could modify the display. The goggles are designed to display speed information inside the eye view space. Don found that the display was not in quite the right place. Modification will begin when Jamie is back from vacation.

Quadfoiler Test – Oct 9

10/9/08

Notes: Sliding traveler did not seem to make any difference in boat performance. Moving the kite attachment point forward resulted in increased bar pressure. Crane launch worked well. Kite launch is slightly awkward due to breakwater but still do-able in reasonable conditions.

Kite Generation animation

Aug 21 2008

This was the first movie created to simulate kite-assisted power generation. The boat model was based off of 2D drawings from YCO and group. The model was made from a solid in SolidWorks and the animation was made in 3D Studio by Victor.
