PHILBROOK'S BOATYARD RESTORATION OF THE MOTOR YACHT CANIM
AUGUST 2002

Foam Core Materials in the Marine Industry

Philbrooks Boatyard
 

Built in 1930, the Canim was an immediate head turner. She was one of four 96 footers built by Lake Union Drydock to an L.E. (Ted) Geary design. Geary was already a seasoned Naval Architect when he was commissioned to draw Canim for Seattle Times publisher, Col. C. B. Blethen. Blethen wanted to go yachting in style and Geary's design would be the toast of the Seattle Yacht Club. After all, in those days 96' yachts were rare. Her impressive length aside, Canim presented a unique challenge for the Philbrook's team. Their job was essentially to reverse the clock, with a goal no less ambitious than to restore the yacht's very soul.

FOAM CORE MATERIALS IN THE MARINE INDUSTRY
APRIL 2002

Foam Core Materials in the Marine Industry

DIAB, Inc.
 

For over 60 years foam cores have been utilized in marine applications to lighten, stiffen, and strengthen everything form hull bottoms to fly bridges. But what exactly is foam core? What type do I use, and where can I use it? Should I use it instead of balsa or plywood? With the seemingly endless variety of foam core materials on the market today, it can be frustrating for the average boating enthusiast to find the right foam core for his/her particular application. This article will attempt to inform boat builders about the properties and correct manufacturing procedures involved in constructing foam core sandwich laminates.

CALL FOR ARTICLES

We would like to begin featuring design articles on a more regular basis covering a wide variety of subjects which would be of interest to professional designers, design students, and the general public as they select their next yacht or as they chose a designer and builder to realize their dream.

If you are a designer, boatbuilder, or involved in the marine industry and would like to contribute an article to be included on Boat Design Net, please contact us.

To get the process started, we have come up with a preliminary topic list, but only to provide an idea of the type of articles we are interested in featuring. The following list is just a start.  If you might be interested in contributing an article, we welcome your suggestions.

Design:
Air-entrapping hulls
Step design.
What's the next evolutionary step for the catamaran or tunnel hull forms?
Wave piercing hulls
Hydrofoils
Fast Ferries
Reduced-wake design
Surface effect vehicles (and the winged "bat boats")
New design software.

Boatbuilding:
New Composite Manufacturing Techniques
VEC molding, CAD/CAM/CNC vs. traditional boatbuilding, the advantages of traditional materials such as wood and cold molded hulls, alternate homebuilding techniques, environmental concerns, vacuum techniques, the future of composite construction.

Career Paths for a Naval Architect. A look at how a young Yacht Designers should get started, both in terms of theoretical and practical education and paths into the industry, small boatbuilders, custom one-off and limited production yacht construction.

We would like to arrange to publish articles on a wide variety of subjects, certainly not limited to the above.  In return, we will offer authors and contributors publicity (5000 page views per day), prominent links to your web site and/or contact information, and any web services which might be requested or required. We look forward to your input.

Sincerely,
BoatDesign.Net
