What this video covers

The crew of the custom aluminium catamaran Delos 2.0 installs a complete anchoring system, focusing on galvanic isolation and mechanical integration. They select a 105-pound Mantis M2 anchor, chosen for its roll-bar-free design that allows a snug fit against the bow.2:09 To prevent corrosion between the stainless steel anchor chain and the aluminium hull, the team machines custom bushings and a bow roller from Acetal, a low-friction engineering thermoplastic.7:21 They fabricate a custom aluminium chain box with an angled floor to ensure proper chain stacking and line the interior with plastic to further isolate the metals.12:11 The system utilises a Vetus Maxwell RC-12 windlass, controlled by a custom-wired electronics panel that integrates Selden control boxes for the boat's electric winches and furlers.21:31 Testing confirms the 100-metre stainless steel Chromox chain feeds smoothly into the locker without snagging.31:07 Proper isolation of dissimilar metals and careful geometry in the chain locker design are essential for long-term reliability in aluminium boat construction.
