    Topic: "The Quadrimaran": Four identical wedge-shaped planing hulls
    William Hockberger: Chair of SNAME SD-5 & a Naval Architect and Independent Consultant

    The Quadrimaran has four identical wedge-shaped planing hulls that are flat on the bottom and
    sloped downward toward the stern. It was designed to operate at 45-60 knots but with relatively
    lower drag than other high-speed ships, yielding power and fuel savings to compensate for the
    increases in structure and outfit from having four hulls.
    A 57-foot prototype impressed prospective investors and buyers, and several major European
    companies supported further development and designs, with the major classification societies
    involved. An 85-foot passenger ferry was built for Caribbean operation, and numerous other
    designs were done, but contractual and financial problems stopped further construction.
    The concept gained a degree of acceptance in the US for possible high-speed sealift application,
    but recent analysis has shown that the problems experienced were due to fundamental technical
    reasons, which will be discussed and explained. The French inventor has reenergized his
    promotion of the Quadrimaran, so it is again a timely subject.
    William Hockberger is a naval architect and independent consultant in marine systems
    planning, design and development. Following 27 years in the US Navy's ship design
    organization, he now works mainly on commercial marine systems, especially ferries and
    intermodal freight. He has a particular interest in high-performance ship design and chairs
    SNAME's SD-5 Panel on Advanced Ships and Craft.
    Bill holds a bachelor’s degree in naval architecture and marine engineering (MIT), master’s
    degrees in operations research (MIT) and applied economics (American University), and is a
    Registered Professional Engineer. Besides SNAME he is a member of IHS and ASNE and an
    affiliate of the Transportation Research Board and active on its Committee on Ferry
    Transportation and Committee on the Logistics of Disaster Response and Business Continuity.




Topic: Joint High Speed Vessel (JHSV) Design & Delivery Update
Stephen L. Kantz: NAVSEA Ship Design Manager


Presentation Posted from JOINT IHS/SD-5 DINNER MEETING:

"Topic: Ship to Shore Connector (SSC) Design Development /Evolution" - 7 May 2015

The most recent Joint Dinner meeting with SNAME SD-5 Panel was held 7 May 2015 at the Army-Navy Country Club in Arlington,VA with a maximum capacity attendance of 70 people.Jay Howell: CSC Advanced Marine Center, made an excellent presentation on "Ship to Shore Connector (SSC) Design Development /Evolution". Fully amphibious LCACs (Landing Craft, Air Cushion) were first delivered in December 1984 with a 60 short ton capacity and an expected service life of 20 years; 91 were acquired. In October 2006 the Navy formally commenced the SSC program to provide a functional LCAC replacement with the same “footprint”, a 74 short ton capacity, increased range, a 30 year service life, and improved reliability and maintainability. A significant design effort was applied to
addressing the “Top 25” LCAC maintenance items, and the Navy employed a Set-Based Design process to optimize the selection of systems for the SSC. The Technology Readiness Assessment process was rigorously applied to ensure new technologies included would be fully ready. Mr. Howell discused some of the aspects of the early stage design development and how the SSC has evolved from the LCAC and answered many questions from those present.

    Topic: Unmanned Applications of Advanced Marine Vehicles in the U.S. Navy

    by Michael Bosworth
    PEO LCS Science and Technology Director

    Advanced Marine Vehicles have found a number of applications in naval service, notably
    SWATHs for high seakeeping, hydrofoils and trimarans for small combatants, and hovercraft for
    amphibious lighterage. A newly emerging area of development is unmanned maritime systems
    (surface or underwater). USVs and UUVs are less developed and less transitioned as a class
    than Unmanned Air Vehicles (UAV), with energy and autonomy/communications issues to
    overcome, respectively. But unmanned maritime systems represent a grand opportunity for
    AMV concepts, if they can translate from manned concepts to often smaller unmanned concepts.
    Mr. Bosworth will discuss some emerging UMS missions and needs and opportunities, then lead
    a short discussion session about the melding of AMVs and UMS's as a developmental tool.
    Mike Bosworth graduated from the US Naval Academy in 1976 and spent 20 years in uniform in
    a wide variety of positions, first as a Surface Warfare Officer and then an Engineering Duty
    Officer. Midway through he attended MIT for a master's in Naval Architecture and Marine
    Engineering and the degree of Ocean Engineer. After retiring in 1996 he worked at Syntek
    Technologies for 6 years before returning to NAVSEA, where he has spent the past 13 years
    building surface ship and craft concept design, and R&D management and transition capabilities,
    in NAVSEA 05D and 05T. He recently left as deputy of 05T (the NAVSEA corporate CTO
    group) to take the position of Science and Technology Director for PEO LCS (which includes
    LCS, the new frigate derivative, mine warfare, and unmanned maritime systems).

Topic: 50 Years of Hovercraft in the USA Put into Perspective
Speaker: Warwick Jacobs, Trustee, the Hovercraft Museum

Although the hovercraft was officially invented in the UK back in 1955, the US has had a long
association with it and has now seen half a century of activity and contributions to it. From
GEMs (Ground Effect Machines) to ACVs (Air Cushion Vehicles) to SES (Surface Effect
Ships), the “hover craft” has had a presence in the US, and Warwick will discuss both its
military and civilian roles and explain the successes and failures. From the San Francisco ferries
and Vietnam conflict in the 1960s to the dream of a 100-knot Navy to present day giant military
craft worldwide, he will trace the rich diversity of hovercraft and what the future may hold. He'll
touch on today's hovercraft sporting and cruising clubs and their great differences from the UK.
Warwick Jacobs is a trustee of the Hovercraft Museum in England and one of its founders. The
Museum now has over 70 full-size craft, including the SR.N4, the largest civilian hovercraft ever
built. He has been a hovercraft enthusiast from the age of four and has seen (and now acquired)
many of them. He knew Sir Christopher Cockerell, the hovercraft inventor, and was even
commissioned to paint his portrait (he's also a professional painter). Earlier he worked with the
ferry operator Hovertravel and cofounded and ran the company HoverHire. In 2012 he helped
HoverAid in southern Madagascar with their Hovering Doctor service.
Warwick's University of London degree specialized in transport geography, his thesis being
“The Hovercraft and the Difficulty in Finding a Modal Role.” He was for 15 years the honorary
Secretary of the Hovercraft Society.



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
