This is an affordable hull with a high end flair. The MATRIX ES is started with multiple coats of epoxy primer. The hull consists of E-Glass with S-Glass strategically placed to take extreme abuse for years to come. The laminates are pre-impregnated using premium vinylester resin to ensure a lighter weight and improved strength. Composite components are then fused together using top of the line structural methacrylate adhesive. Do not let the ES price tag fool you- this is a superior Trinity product.
