What this video covers
The crew of Catalpa repairs extensive hull osmosis and replaces through-hull fittings while the boat remains on the hard. After identifying numerous small blisters across the hull, the owner determines that stripping the surface with a planer and re-glassing would have been more efficient than the time-consuming process of patching individual spots with epoxy.2:47 The project involves removing a custom stainless steel through-hull fitting that showed significant electrolysis and corrosion, which the crew replaces with a standardized three-inch fitting mounted on a custom-built epoxy block.6:34 To address surface irregularities left by the planer, the crew applies a fairing compound to smooth the hull before painting.11:51 The owner, a former plasterer, utilizes his professional experience to fill divots and fair the surface.11:16 The work concludes with the final removal of through-hull valves and the preparation of the waterline for antifouling paint.5:53 Patching numerous small osmosis blisters is labor-intensive; stripping and re-glassing the affected laminate is often a more effective long-term repair.6:01
