Apprentice For A Day Public Boatbuilding Program
Runs most Saturdays and Sundays
Journeyman Special: Choose any 4 classes for $150 CBMM members and $200 non-members Single classes: CBMM members $45 and non-members $55. Learn traditional boat building under the direction of a CBMM shipwright. You can be part of the whole process or just sign up for those aspects of building a boat that you want to learn. Must be 16 or older unless accompanied by an adult. Join Boatyard Program Manager Jenn Kuhn. Email questions to email@example.com or call 410-745-4980.
2016-2017 Construction: 25’ Draketail” Chesapeake Bay Fishing Launch has completed, with Pintail now available for purchase by contacting Jenn Kuhn.
Pintail is a 25′ Hoopers Island draketail built at CBMM and is now available for purchase.
The boat features a white oak duck walk, sapele coaming, sassafras-oiled floorboards, marine plywood battery box, and mahogany seats.
She also boasts a brand-new, two-cylinder 14 hp Yanmar diesel engine, electronics panel, steering gear, and systems hook up. Proceeds from her sale support the education, restoration, and exhibition programs of the non-profit museum.

Each week we work on a specific topic which relates to the overall process of building a boat.
Full-sized drawing of the boat based on measurements or plans showing profile, half-breadths & body plan. Lofting details are the dimensions, shapes, and locations of all parts: stem, keel, expanded transom, molds as well as seats, mast centerboard, trunk and engine.
The body plan (cross-section) shapes are traced from the lofting to the mold stock. Molds become permanent frames in some boats, but often are temporary until the hull is complete. The expanded transom, keel and stem are built at the same time.
Accuracy and strength are vital. Level the strong-back, draw center and station lines, then fasten molds, stem, transom and keel.
Plank shapes are derived by lining off the erected molds, using battens to divide the area to be covered. Spiling is the process of measuring each plank from this shape. The shaped planks are dry fitted, smoothed and fastened in place.
AFTER BOAT IS UPRIGHT
Many components must be built and installed, such as knees, breast hook, in-wales, seat risers, seats, and centerboard trunk. Removable parts including spars, centerboard, rudder and tiller, oarlocks, oars, sails, hardware and rigging are all part of the process.
From the plans, the dimensions, the type of spars and rigging are determined. Timber for spars is milled, cut to dimension, assembled and then shaped. Many of these small, light sailing craft benefit from fitting a hollow wooden mast, which can be constructed using the “bird’s mouth” technique.
ADHESIVES AND FASTNINGS
Discussion of relative strength and durability of glues, caulking compounds and metal fasteners of all types helps us to determine the optimum combinations to ensure long boat life.
From the plans, we determine the overall dimensions of the sail, lofting it on the floor with the draft location and desired camber in mind. After adjusting each panel and sewing them together we adjust the outside dimensions adding curves and hollows where intended. Some of the final touches are hand sewn grommets and bolt ropes.
