On a mechanical cable over sheave steering system, which factor is NOT taken into account for cable clamp attachment?

In the context of a mechanical cable over sheave steering system, the cable clamp attachment is primarily influenced by factors that directly affect the performance and safety of the steering mechanism. The correct answer highlights that vessel type is not typically considered when determining the specifics of cable clamp attachment.

Cable size is crucial because it ensures that the clamp securely holds the cable without causing damage or slipping. The orientation of the clamp is important as it ensures the cable moves freely and doesn't experience undue stress or interference during operation. Additionally, the location of the clamp is significant to maintain optimal tension and routing of the cable.

While the type of vessel may influence broader design choices regarding steering systems, the technical requirements for cable clamp attachment remain largely consistent across different vessels. Therefore, vessel type does not directly impact the specific considerations for cable clamp attachment in the way the other factors do, making it the correct choice in this context.
