What this video covers
Sven Yrvind fabricates and installs a port-side mast holder on his boat to ensure a leak-free seal.▶ 0:37 The process involves drilling mounting holes in cramped quarters, followed by shaping the component and applying glass fiber with thickened epoxy fillets.▶ 0:04 Copper pipes are integrated into the design to serve as drains, with the added benefit that marine growth avoids the copper material.▶ 1:04 The installation sits well above the waterline.▶ 0:45 After completing the port side, the same lamination and sealing process is applied to the starboard side.▶ 1:37 The work requires filling existing holes and shaping the fiberglass to ensure structural integrity and water tightness.▶ 1:56 Proper sealing of mast penetrations prevents water ingress and protects the hull structure.
