What this video covers

Johan and Malin continue the structural rebuild of their boat’s keel grid by installing and gluing 18 fiberglass-coated cedar stringers into the hull.3:04 The process involves precise leveling with a laser and using peel ply on epoxy fillets to achieve a smooth finish that requires minimal sanding.13:47 To ensure proper curing in cold, humid conditions, the work area is maintained at 30 degrees Celsius using a 9-kilowatt electric heater.1:07 The project also includes insulating the house attic with loose wool to improve heating efficiency.4:15

Addressing design questions, Johan explains that the stringers are kept lower than the floors to allow for cable and hose routing along the sides of the grid, keeping the bilges clear.19:05 The keel connection design features a 20-millimeter-thick top plate and 26 keel bolts, with additional brackets planned to clamp the grid to the hull to prevent delamination during a potential grounding.20:14 The choice of a longer keel over a high-aspect-ratio design aims to distribute grounding forces over a larger surface area.22:27
