CORROSION

A boatowner's introduction

2-HOUR VIRTUAL MASTER CLASS
Friday, June 26, 2020 | 10:00 a.m. – 12:00 p.m. PT

In this introductory class, NWSWB Lead Marine Systems Instructor Kevin Ritz will introduce students to the fundamentals and concepts related to marine corrosion on boats of all types of hull composition. Students will receive an overview of corrosion fundamentals and how a boat’s electrical system affects corrosion aboard.  Students will also learn about cathodic protection considerations as well as an overview of a basic corrosion survey. 

Registration is closed.

We are exploring options  to offer a paid recorded video link to those who were unable to register or attend the live session of this class. Please sign up for our enews for notices when this option becomes available.

Corrosion is an all-too-common result of electrochemical reactions between materials and substances in their environment. Marine corrosion can exist in several forms such as pitting, galvanic, stray current and cavitation corrosion and is found in all hull types. It can be a dangerous and an extremely costly problem. Marine corrosion can be prevented by careful study and use of corrosion reducing materials, designs and coatings.

2-HOUR VIRTUAL MASTER CLASS
Friday, May 22, 2020 | 10:00 a.m. – 12:00 p.m. PT

In this introductory class, NWSWB Chief Instructor Sean Koomen will introduce students to the tools, techniques, and sequences used when lofting a round bottom boat.  Using a combination of Rhino, a live lofting floor, and live virtual lecture (via Zoom), Sean will guide students through the lofting process.

Lofting is the process of drawing a boat hull full size on a lofting floor. This series in lofting brings together an appreciation of the lines of a hull with an understanding of its structure. The precise application of sound lofting principles is an essential skill. It is here that the real construction of a boat begins. Lofting and creating patterns makes boatbuilding predictable. The patterning and construction of all the major components of the hull makes for quick, accurate, and efficient assembly of the vessel.

Friday, May 22, 2020
10:00 a.m. – 12:00 p.m. Pacific Time

  • No Previous Lofting Experience Required
  • Cost: $20.00 USD
  • Length: 2 hours ( Two 50 minute sessions)


SEAN KOOMEN
NWSWB Chief Instructor
sean@nwswb.edu

Sean has packed several lifetimes of experience in boatbuilding and craftsmanship since he graduated from the Northwest School of Wooden Boatbuilding in 2004. While still attending college studying cello performance at St. Olaf College in Minnesota , Sean launched his own small boat shop. Subsequently, he worked at some of the most prestigious boat yards in the country, concentrating on historically significant vessel restorations, including the 138-food Steam Yacht Cangarda and the 1929 Schooner Viveka, at Rutherford’s Boat Shop in Richmond, CA. Sean led the restoration of Wanda, a 90-foot Ted Geary design. He also worked as a shipwright for the San Francisco Maritime Museum before heading to Maine to expand his skills in new construction and cold molding at Brooklin Boatyard.

LOFTING: Part II

A Look at complex developments - a curved, raked transom

2-HOUR VIRTUAL MASTER CLASS
Friday, May 29, 2020 | 10:00 a.m. – 12:00 p.m. PT

In this class, NWSWB Chief Instructor Sean Koomen will guide students through a complex lofting development. A development is any aspect of the completed lofting that is drawn or developed further to create an actual pattern for a piece of the boat.  Using a combination of Rhino, a live lofting floor, and live lecture (via Zoom), Sean will guide students through the development process.
