MCGR - Marine Composites & Gelcoat Repair

Taking composite material repair and modification technologies for marine vessels to the NEXT LEVEL!

This course provides an exceptional overview of the both the essential and advanced methods, technologies, equipment, materials and processes involved in the repair and modification of composite boats of all sizes. The latest materials technologies utilizing glass fiber, carbon fiber, aramid fiber (Kevlar™) and polyethylene-based fabrics will be applied during the hands-on shop exercises in the course.

Polyester, vinyl ester and epoxy resin systems will be demonstrated and used in the shop. Lectures supported by PowerPoint and video presentations will be provided each day as will shop exercises that challenge the trainee to perform complex repairs that are vacuum bagged and cured with heat control.

Topics covered in this 5-day course include:

  • History & trends and recent developments in composite materials for Marine Manufacturing & Repair processes
  • The science behind composite materials; resin (matrix) systems, single & hybrid fiber reinforcements and core materials
  • Composite boat design, the basic essential theory of composite materials in marine structures design
  • Detection of flaws and damage in composite structures using various inspection methods, i.e. Tap-Testing - mechanical impedance, ultrasound and infrared thermography
  • Health and Safety; handling and disposing of composite chemical substances, repair shop requirements for quality control of composites
  • Structural repair techniques & procedures, and quality assurance for modern boat design using advanced glass fiber and carbon fiber materials
  • Material handling; required shop practices environmental controls, cutting, grinding, sanding, laminating, and post-cure methods
  • Vacuum bagging and curing processes for wet-layup localized repairs
  • Gelcoat colour matching and restoration



Prior composites experience or training is not required.
