The term boat canvas refers to that work which is concerned with design and production of functional canvas products especially for sail and motor boats.
Boat canvas is often used as a protection against the harmful UV rays. Since the UV rays damages the varnish and the sail materials, the boats are need to be prepared repeatedly to prevent the regular repairing the boats are covered of fabricated canvas. The hatches are covered with canvas for indoor sun protection and the winches of boats are covered to protect from deteriorating from rain and airborne particles.
There are different types of marine canvas including biminis and dodgers these are used for protecting the parts of boat from the weather creating a comfortable environment for the boat owner. Sometimes boat canvas is also used for enhancing the decoration of the motor boat or sail. In U.S.A the boat canvas creators use especially the Sunbrella acrylic fabric though certain other brand of acrylic canvas is also available.
The boat canvas of light colors destroys more quickly in the sun and sometimes it even loses its strength within the first few years. Dark color canvas like darker greens, Pacific blue, and black have long lasting capacity they can last for up to 20 years even in the tropical places.
The threads used for stitching the boat canvas is often made of polyester the reason behind using such threads is that polyester threads are highly resistant to ultra violet rays. Nylon threads are never used since they do not last for more than six months when exposed to sunlight. Polyester threads have greater lasting capacity.
Long thread sizes are used for stitching the boat canvas since the smaller thread sizes are not appropriate for tropical regions and because of frequent loss of strength that results from exposure to high ultraviolet rays. It is good to keep one of the two stitch lines not exposed to the direct contact of sun. This is only possible by stitching the canvas by providing the stitch-turn-and topstitch technique, instead of stitching both lines on the same side
