What this video covers

Andy reinforces the transom arch on a Bertram 25 by filling a three-quarter-inch deep trough with thickened epoxy.3:12 To manage the exotherm, he performs the fill in two stages, waiting for the first pour to pass its peak heat before adding the second.3:42 He then laminates the structure with 1708 biaxial fibreglass, applying the fabric at an angle to maintain tension and minimise air bubbles.13:24 After the glass cures, he cuts pockets into the port and starboard sides of the deck to install half-inch Coosa board supports.15:06 These supports will serve as the mounting base for the arched transom piece and the aft compartment lid.16:14 He uses a conservative cutting approach to avoid damaging the surrounding deck coring while creating the necessary clearance.15:23
