SV IdaLina – Ingmar Ravudd SWE – UPDATE 14.04.2024

CONSIDERATIONS ABOUT THE LOSS SV IDA LINA

The ARCONA 460 is designed as a performance cruiser with wheel steering, which has a diameter of + 1.10 m and presumably manages with approx. 1.2 revolutions between the stops, i.e. a very direct power transmission to achieve considerable rudder angles with only small rudder deflections at the wheel.
In the first few seconds of the video we can see that the countered nuts for tensioning the cable transmission between the wheel and quadrant … are no longer present, nuts that are still present on the other side. It can be assumed that these nuts were able to work themselves loose over a longer period of time (presumably without being checked!), which could have resulted in the necessary rudder deflections becoming steadily greater. Presumably the autopilot
was activated so that the „slack“ in the cable transmission went unnoticed by the Crtew. The cause of the damage could therefore be that the rudder with pre-balance component was increasingly exposed to considerable vibrations because it was no longer limited by clear control signals, but instead deflected uncontrollably.
