What this video covers
After six months in the water, the wooden boat *Arabella* was hauled in Rockland, Maine, to address bottom paint failure and rapid zinc erosion.0:08 The hull’s oak planks swelled significantly, causing seam compound to extrude and create ridges that blistered and flaked the paint.5:21 Scraping revealed that the paint failure was most severe along plank seams and on wider planks like the garboard, while the lead ballast keel remained unaffected.7:54 To prevent further peeling, the crew scraped the hull to bare wood in affected areas, applied new bottom paint, and raised the waterline by eight inches.8:57
To address the rapid zinc loss, the crew replaced the existing stuffing box packing with traditional PTFE flax.22:55 The previous packing was suspected of containing graphite, which may have caused galvanic corrosion.22:49 The crew also performed routine maintenance, including replacing the propeller zinc and ensuring the stuffing box was properly adjusted to allow for a slight drip.4:34
