August 1, 2014

As you know, IHS has been conducting a competition for the Mandles Prize for Hydrofoil Excellence. Mr. Martinn Mandles, a long-time member of IHS, and his wife Connie generously offered to fund up to $5,000 a year in IHS hydrofoil technology achievement prizes for students. The competition includes a $2500 First Prize and up to two $1000 Honorable Mention awards. Background on the Mandles Prize and rules for the competition are at:

The Mandles Prize competition is an outstanding opportunity for the next generation of hydrofoil developers to be acknowledged for their achievements in advancing the state of the art in hydrofoil and hydrofoil-assisted craft technology and design.

We received ten entries for the Mandles Prize reflecting a wide range of hydrofoil-related technical investigations and assembled an outstanding panel of judges to review them. I am pleased to announce the results of the competition and congratulate the winning students and their faculty advisers for their outstanding work. The Mandles Prize awards for 2013 – 2014 are as follows:

First Prize:

“Speed Sailing Design and Velocity Prediction Program”
by Dane Hull
Australian Maritime College, University of Tasmania
Faculty Adviser: Dr. J. R. Binns

Honorable Mention:

“Design and Assessment of an Ultra High Speed, Surface-Piercing, Supercavitating Hydrofoil Craft ”

Honorable Mention:

“On the Design, Construction and Testing of a Fully-Submerged Canard Hydrofoil System for a Low-speed Solar Boat”

Faculty Adviser: Dr. Timothy Dewhurst

We thank all the competitors and their advisers for their interest in hydrofoil technology and their truly excellent work. Thanks also to our judges for contributing their personal time and expertise in evaluating the entries. All of you have made this first Mandles Prize cycle a resounding success!

John R. Meyer's Bio




To All IHS Members:

The IHS has embarked on a wide range of initiatives aimed at increasing awareness of hydrofoil and hydrofoil related technology developments around the world. The Board has had lengthy discussions and concluded that it is critical to involve the membership to accomplish these objectives. There is simply too much work to be done to rely totally on the Board members. I am writing to encourage and solicit your active involvement in the work of the Society.

Specifically, we need assistance in the following areas:

- Newsletter – preparing articles and editing

- Mandles Prize – Judging

- Website – assistance to the Webmaster including responding to posted messages.

- Treasurer – assistance to the Treasurer and Membership Committee.

- Program – assistance in identifying guest speakers for IHS/ SNAME Panel SD-5 Joint Dinner Meetings

- Tacoma Maritime Fest (24 – 25 Aug 2013) and other future meetings/conferences– Staffing the booth

- Navy Hydrofoil Reunion in Key West (20 – 23 Sept 2013) – register to attend.

- Permanent Hydrofoil Exhibit at Washington Navy Yard Museum – assistance/lead in developing the exhibit

- Phanfare Photo Site on IHS website – assistance in posting photos or editing/describing the content.

- Collection/compilation/indexing of hydrofoil (and other AMV) technical papers and data.

Many of these support activities can be done at home over the internet or phone and can be at any level of engagement that volunteers are willing and able to provide, either one-off or ongoing. I urge all of you to consider where you might help in furthering these efforts. Please contact me at: if you’re interested.


Mark R. Bebar – President, IHS

Island Engineering, formed in 1999, is dedicated to design and engineering support of high performance marine vehicles - primarily for the development of advanced ride control systems.

Island Engineering is one of a very few companies that specialize in providing the stabilization and motion control that a ship or craft requires in order to be able to accomplish its purposes.  That may involve ensuring a ship-launched weapon will hit its target, or a helicopter or Rigid Hull Inflatable Boat can be deployed safely, or a yacht owner's martini won't spill.  Requirements and solutions can vary widely from one case to the next, and Island Engineering has dealt with a wide variety of ships, craft and equipment involved in such solutions. Island Engineering handles all aspects of this work, from basic analysis to design and engineering, all the way to fabrication and shipboard installation of stabilization systems. 

Moreover, the company is well known for its ability and willingness to tackle all manner of unusual and challenging engineering projects.
