Fairing Fiberglass Boats
Building a custom fiberglass composite pilothouse allows an older sailboat or powerboat to be transformed without relying on traditional plywood construction. These projects show how I use Coosa Board, epoxy and fiberglass to design and fabricate lightweight, waterproof pilothouse structures, including bulkheads, roofs, window openings and curved surfaces. The result combines composite boat-building techniques with practical DIY fabrication to create a strong, rot-resistant pilothouse specifically fitted to the existing hull.
The devil is in the details. Make it look proper.
Fairing fiberglass creates a smooth, consistent surface after fiberglass repairs, modifications or new composite construction. The process typically involves applying epoxy fairing compound, shaping and sanding the surface, identifying high and low spots, and repeating the process until the fiberglass is ready for primer and paint.
These projects show how I fair fiberglass boat surfaces during actual restoration and construction work, including finishing a custom composite trawler hardtop. Fairing allows fiberglass seams, joints and structural transitions to disappear into the finished surface, creating the smooth appearance of a molded fiberglass component.
