Fibreglass Fabrications and Modifications


Blackline Marine has extensive experience with modifications to all types of fibreglass boats from propane lockers to hull extensions. Hull extensions can be immensely practical, improve fuel economy, speed and stability, and is in many cases more cost effective than the purchase of a larger boat. Bring us your idea and we’ll make it a reality.
