Topic: High Speed Planing Craft, the evolution of a species
Presenter: Prof. Stefano Brizzolara, PhD, Virginia Tech, Blacksburg, VA

Topic:

Dr. Brizzolara calls planing hulls “the emblematic category of high speed marine craft.” He will
start by reviewing the most significant planing hull designs of the past and their famous
designers, in Europe and the USA, such as Renato Levi, Peter du Caine, Pietro Baglietto, Eugene
Clement, Donald Blount, Ray Hunt; and their builders such as Riva, Pershing, FB Design, Wally
and Overmarine. He will explain their hydrodynamics and how they have integrated hull and
propulsion, touch on aspects of styling, especially for yachts, and show that few important
innovations have come in recent decades. He will then present new ideas and concepts that
appear to offer dramatic performance improvement. One of those, the Stepped Cambered
Planing Hull with Hydrofoils (SCPH2), has shown drag reduction of more than 30 percent in
model scale tests, compared with present designs.

Bio:

Stefano Brizzolara is Associate Professor in ocean vehicle dynamics in the Aerospace and Ocean
Engineering Department at Virginia Tech, as well as a research scientist at MIT, where he
founded the Innovative Ship Design Lab, iShip. As a Naval Architect and Marine Engineer with
a PhD in numerical hydrodynamics for ship design, he gained a solid high tech ship design
experience in the Navy Shipbuilding Division of Fincantieri, in Genoa, Italy. He developed
numerical methods for high-efficiency low-noise propeller design and unconventional highspeed
hull form design and optimization that have led to several innovative hull form and marine
propulsor technologies. He is the author of more than 150 scientific papers and inventor of six
patents (two pending).

Multi-Agency Craft Conference (MACC)

June 8-9, 2016 United States Coast Guard Yard, Baltimore, MD

The Multi-Agency Craft Conference (MACC) is an open forum for the exchange of operational and technical information on small boats and craft between Government agencies and the maritime community. The American Society of Naval Engineers (ASNE) is proud to announce that MACC 2016 will be held at the United States Coast Guard Yard in Baltimore, MD. The USCG venue allows us to broaden the community reach of those looking to acquire small craft and high speed boats. As with previous MACCs, the exhibit tent will feature 100+ booths, live in-water boat demos, static displays, technical sessions, and high-level keynotes and panel presentations. We are extremely excited since this venue not only allows us the opportunity to incorporate panel & technical session rooms within the exhibit tent, but also provides ample outdoor pavilion space for the evening’s networking Coastal Social and close walking proximity to the in-water boat demos.

Since its founding in 1998, MACC has served as a primary venue for leveraging knowledge and lessons-learned across multiple Government agencies that develop, procure, or operate small boats and craft. Previous conferences have covered a broad range of topics including: requirements generation, boat and craft design, acquisition processes, maintenance and repair practices, logistics and training, and new technology development and integration. The shared information results in effective use of resources, opportunities for collaboration, a more knowledgeable industry-base, and best-value small boats and craft for all end-user communities.
MACC is BACK…

While navies around the world no longer have operational hydrofoils, these craft are regularly
employed commercially and recreationally, most dramatically in the latest America’s Cup
competitions. Interest is especially strong and growing in the “informal sector” of the maritime
world, where individual researchers and builders are developing hydrofoils in a wide range of
configurations, as an internet search will quickly reveal. The innovations are exciting, and
performance records are often broken.

Ray Vellinga is a noted figure in that world. In the late 1960s, after receiving training in
aerodynamics, he began trying to make things fly, first in aviation but then with hydrofoils. An
early attempt to make a business of it convinced him that would be financially uncertain, and he
pursued a successful career in industrial real estate development instead. But then he went back to
hydrofoils with complete freedom to create and innovate. The result has been a series of small
hydrofoil craft plus his well-received book, Hydrofoils: Design, Build, Fly, which shows that
typical enthusiasts can actually be hydrofoil creators and flyers.

Ray will show videos and photos of many different small hydrofoil designs, including his own but
also from other developers, and discuss their features and performance. He will also show some
larger craft that originated in this informal sector, including the AC72 America’s Cup racers.
After graduating from Bradley University in business Ray entered pilot training with the US Navy
and was at the top of his class studying aerodynamics in preparation for a year of pilot training in
T-28s and T-34s. He left the Navy as a Lieutenant and received his commercial and instrument
rating as a civilian pilot. He has flown or created numerous human-powered, motor-driven, and
wind-powered small hydrofoils. Ray is currently an owner of the Gig Harbor Marina in
Washington (www.gigharbormarina.com) and a member of the Board of Directors of the
International Hydrofoil Society.

Last JOINT DINNER MEETING of SNAME SD-5 PANEL AND INTERNATIONAL HYDROFOIL SOCIETY

Topic: “The Quadrimaran”: Four identical wedge-shaped planing hulls

  • Wednesday, 3 February 2016
    Romaine salad
    Grilled marinated chicken paillard with saffron cous cous and broccolini
    Deep dish apple pie, Coffee & tea

    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.

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.

Advanced Marine Vehicles Opportunities in Unmanned Maritime Systems” – 5 February 2015

The most recent Joint Dinner meeting with SNAME SD-5 Panel was held 5 February 2015 at the Army-Navy Country Club in Arlington,VA with a maximum capacity attendance of 70 people. Mr. Michael Bosworth, PEO LCS Science and Technology Advisor, made an excellent presentation on “Advanced Marine Vehicles Opportunities in Unmanned Maritime Systems”. Unmanned Surface Vehicles (USVs) and Unmanned Underwater Vehicles (UUVs) are less developed and less transitioned than Unmanned Air Vehicles (UAV), with energy and autonomy/communications issues to overcome, respectively. But unmanned maritime systems (UMS) represent a grand opportunity for AMV concepts, if they can translate from manned concepts to smaller unmanned concepts. Mr. Bosworth discussed some emerging UMS missions and needs and opportunities and then led a short discussion on this emerging technology development.
