Using Epoxy – Fibreglassing, Glass Taping, Glues and Gluing, Coating with Epoxy, Laying Teak Deck overlay veneer, Repairing Wood Rot

Fibreglassing 1 – small areas – eg fibreglassing chines or joins between hull panels

Fibreglassing 2 – double bias tapes and glassing small complex areas

Fibreglassing 3 – bigger areas – centreboards, rudders, leeboards, keels and larger hull areas
