Bourne Method - Innovative Boat Building
One of the most innovative methods of building boats is the Bourne method bourneboats.com, which uses sprayed polyurethane foam as an integral part
of the construcution of GRP boats. What's really different about this method is that the boat is built from the inside out. The Bourne method brings
numerous advantages to the yacht builder:
Construction using the Bourne method
The first step in the construction is to create the basic hull shape with steel mesh normally used in the construcion industry.
Complex curves are achieved rapidly and with ease. This method of construction can be used for most kinds of hull construction, including hard chine and radius chine.
The next step is fitting out the boat. At this stage the hull is incomplete.
The deck is then foamed with spray on polyurethane foam. The foam is then sanded and faired before the deck is fibreglassed.
Polyurethane foam is then sprayed onto the "hull" where it encapsulates the steel mesh. The foam cures rapidly and can be sanded back to achieve a smooth, true hull.
After sanding the foam the final stage is fibreglassing the hull. The resulting hull is true, strong and was built without the need for frames or moulds.
