Ship Rudder Propeller
The Ship Rudder Propeller is a vertically adjustable propulsion unit that optimizes thrust efficiency by maintaining ideal propeller immersion at all vessel drafts. Designed for easy maintenance, it can be hydraulically or manually tilted out of the water. Available in hydraulic or electric drive, it meets major classification standards (ABS, BV, DNV, etc.).
Key Features & Benefits
✔ Depth-Adjustable Design – Vertical movement ensures maximum thrust efficiency at any draft
✔ Easy Maintenance – Hydraulic/hand-operated tilt for propeller access
✔ Dual Drive Options – Hydraulic or electric motor (900–1750 RPM)
✔ Robust Construction – Alloy body + 4-blade propeller (350–4000mm)
✔ Global Certifications – ABS, BV, DNV, NK, LR, GL, CCS, RINA
