BUILDING SMALL LAPSTRAKE BOATS WITH ERIC HVALSOE
DATE: Course 1 – June 2-9; Course 2 – June 12-16
TIME: 9am - 4pm
CLASS SIZE: 6
INSTRUCTOR: Eric Hvalsoe
LOCATION: South Lake Union
Learn to build a traditional lapstrake sailing dinghy this summer. In this two-part series, famed designer and builder Eric Hvalsoe will build his 16’ combination sail/row boat with students. This course is perfect for people who are interested in learning about wooden boatbuilding, but don’t have the time to attend a full year boat school. Over the course of two weeks students will build a new boat, assembling the building frame, molds and backbone. The hull will be planked cedar lapstrake over the molds, turned upright and framed out. Students will rabbet, spile, steam planks and oak ribs, and pattern and bevel complex components. Ring nails, wood screws, and copper clench nails will be used throughout the construction, as well as the finest lumber. Boatbuilding experience is not a prerequisite – typically student experience and skills vary widely, all part of the fun. Once completed this boat will be rented in our Livery. The materials for this project were funded in Memory of David Allman.

About the Hvalsoe 16: The Hvalsoe 16 lapstrake dinghy is considered by Eric Hvalsoe to be “the great compromise,” as it both rows and sails well. This craft’s fine ends make the Hvalsoe 16 an excellent rowing boat, while it carries enough beam to make it stable under its 85 square foot sprit-sail rig.
Marked by an elegant curved stem and rake wineglass transom, the design is narrow at the ends with a powerful, stable midsection.
The rig is an unstayed, loose footed spritsail. The sprit rig is a model of simplicity and flexibility. It features a convenient brailing line, spruce spars and sail assembly that may be stored inside the boat. Mast, sprit and sail come in a long canvas sleeve for tidy stowage and transport.
These boats will stand upright on the beach with their wide plank keel and are protected with tough, UHMW shoes and rubbing strips. Hull interior are finished with Seafin Teak Oil, exteriors typically painted to the owner's specifications. But don't be fooled by all the gloss, as seats, transom, trim, etc., these boats are coated with an incredibly tough, flexible urethane coating. Results over the years have been proven excellent.
