Diver & Bottom Cleaning Services

The diver is the most-used contractor in any cruiser's regular service rotation. Bottom cleans, zinc swaps, line clearing, the occasional emergency patch — these are routine work that keeps the boat running between haul-outs. In most cruiser anchorages, a good diver is easy to find through the morning net.

What divers do

  • Bottom cleaning: Remove growth, restore antifouling.
  • Zinc replacement: Swap sacrificial anodes on shaft, hull, rudder.
  • Prop and shaft inspection: Check for damage, line wrap.
  • Through-hull inspection: External condition of fittings.
  • Lost item recovery: Tools, anchors, kit dropped overboard.
  • Emergency work: Temporary patches, line clearing, freeing fouled gear.
  • Pre-purchase surveys: Underwater inspection before buying.
