What this video covers

Andy performs structural modifications to the aft deck of a Bertram 25, focusing on mounting and fairing bracing components.Watch He begins by tapering the edges of the deck bracing to prepare for future fibreglass tabbing and structural integration.0:29 To create a clean radius for the transition, he uses a temporary backer, allowing the epoxy to set overnight before proceeding with shaping.4:14 He constructs a custom sanding block from scrap lumber to match the specific curvature of the deck troughs, ensuring uniform material removal.7:07 After scuffing all glossy surfaces to ensure proper adhesion, he fabricates a custom-shaped trowel to apply fairing compound, which he then levels using a longboard to maintain consistent geometry.11:28 He verifies the drainage of the finished surface by testing the water runoff toward the port and starboard scuppers.17:01 The process emphasises the utility of shop-made tools for achieving precise fairing in tight, non-standard spaces.11:11
