STOCK PLANS

BAGATELLE

As shown in our featured designs, Bagatelle is a brand new boat with an unusual mission—to be a new classic design that sails fast.  The plans for Bagatelle are available as stock plans.  Study plans are US$20.00 (US$25.00 for overseas airmail), and the complete plan set, with full-size Mylar patterns is US$3,000.00 (US$3,300.00 for overseas airmail).

Light weight and simple construction meant the boat should be built in wood—strip-planked Western Red Cedar and Douglas Fir veneers using Gougeon Brothers WEST System epoxy resin.  The strip-planking is all tongue-and-groove, 5/8” thick, and the 1/8” thick veneer layers run vertically up the topsides and transversely across the bottom.  The reason for orienting both layers of veneers perpendicular to the centerline is to save on the labor of spiling.

Usually in strip-planked boatbuilding, the outer veneer layers run at ±45°.  In most cases also, the hull surface has compound curvature—as over the surface of a ball—so that as the veneers are laid onto the hull, each strip has to be pretty narrow, and few can butt directly to their neighbors.  During the dry cut and pre-fit of the veneer, a gap of about 2” or so is measured and cut between each piece of veneer, into which is fitted a spile—a piece of veneer that fills the gap.  Spiling is very time consuming.

In this boat, with the veneer strips running 90° to the hull centerline, each strip is bent in only one degree of curvature—as over a cylinder—which almost completely eliminates the need for spiling.  Therefore, hull construction is faster and cheaper.  All veneer strips can be pre-cut to a constant width with perfectly square edges; very few need to be dry fitted; whole gangs of strips can be wet out with epoxy resin all at once and glued to the hull.  The joints between strips are staggered from the first layer to the second for a tight fit all around.

Bagatelle construction profile and general arrangement plan.

The internal structure is laminated Honduras Mahogany frames and floors with foam-cored plywood bulkheads.  The deck is also foam-cored plywood, but whereas the bulkheads are made from off-the-shelf sheets, the deck is built in individual layers, with the foam core replaced by solid wood wherever hardware is mounted.  The cockpit and deck house are built in balsa-cored fiberglass for watertightness.  The drawing below is the Construction Sections drawing, which shows the level of detail that we typically provide on our drawings.

Included in the drawing package are full-size Mylar patterns for the hull and deck.  The example shown below is the Bulkheads Pattern.  There are similar full-size patterns for the frames and floors in the boat.  In addition, full-size patterns and construction details are provided for the rudder and keel.
