What this video covers
Cyclops load sensors, installed on the cap shrouds of the Lagoon 450 Parlay Revival, transmit real-time tension data to a Raymarine Axiom chartplotter via a SeaTalk gateway and to a phone app.0:59 Colin explains the installation: shrouds are released one at a time, held by halyards, and the sensors are fitted in place of standard hardware.2:33 The 16mm wire has a 21-ton breaking strain; the target working load is around 5.5 tons as a reef trigger, with 7 tons as the hard ceiling.0:36 Colin argues that over-tensioning a wide-beam catamaran like the Lagoon 450 levers the hull apart and has contributed to the boat's recurring bulkhead failures.7:59 Separately, Colin and Grant attempt to rebuild the clutch assembly of a Yanmar ST60 saildrive using a new Yanmar clutch kit, working to a 0.1mm bearing tolerance; they break a clutch-selector pin and abandon that unit, successfully rebuilding the second ST60 instead.15:17 Jamie and Colin then reinstall the rebuilt saildrive, calibrate the gear-selector lever to a 22.5mm centre measurement, and torque everything down.20:06 A new diesel injection pump also arrives to replace a previously rebuilt unit that used secondhand parts.11:50
