What this video covers
Replacing two 70x70cm deck portholes on a 40-year-old sailboat requires custom adaptation because the new Plastimo units feature rounded corners, while the existing deck openings are square.3:22 To bridge the gap and ensure a watertight seal, the owner fabricates a custom wooden frame to fit the deck’s metal coaming, then constructs an aluminum perimeter frame to sit between the deck and the new portholes.18:20 The aluminum frame is joined using 45-degree miter cuts and brazed with aluminum welding rods, which include an integrated flux core.24:47 The wooden frame is treated with a saturator to prevent rot from condensation and then sealed with silicone.19:36 The project involves removing old, degraded wood and silicone, treating minor rust spots on the metal coaming, and repainting the area before final installation.11:17 By choosing Plastimo units over higher-priced alternatives, the owner reduces the total cost for two portholes from 5,000 euros to 1,000 euros.1:35 Proper fitment and sealing are critical to preventing leaks in the transition between the square deck opening and the rounded porthole frame.5:00
