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.

Fibreglass Hardtop Fabrication

Customers come to Blackline for fabrication of high-quality, custom parts and boats. In 2009, Blackline built a Farrier F39 Trimaran in epoxy and foam core. Blackline also regularly fabricates hardtops for boats as small as 25′ Hourston Glascraft to 58′ Tollycraft.

We offer a tooling service for the surfacing of CNC machined plugs or CNC “direct to” molds. Marine and industrial mold making and mold resurfacing is available.
