RUDDER SYSTEMS
Marine Rudder Assemblies for Newbuild and Replacement Projects
ERBA Marine coordinates rudder supply around the hull, vessel duty, propeller arrangement, steering connection and available clearances. Existing drawings are preferred for replacement work.
Single- and twin-screw vessel arrangements can be reviewed from confirmed hull and steering data.
Rudder geometry matched to the vessel
Fabricated, cast bronze, GRP-trunk and transom-mounted configurations.
ERBA-Managed Supply
Technical clarification, quotation and supply through ERBA Marine.
Drawing-Led Review
Interfaces checked from verified project information.
Newbuild & Replacement
Support for planned projects, refits and replacement scopes.
GCC Coordination
Regional commercial and delivery coordination.
RUDDER CONFIGURATIONS
Four practical starting points for vessel-specific rudder projects.
Final stock, blade, trunk, bearing and steering-interface details are agreed from the vessel layout and drawings.
Custom & Fabricated Rudders
Fabricated configurations for single- or twin-screw vessels coordinated from hull, stock, blade and steering-interface requirements.
- Stainless or fabricated material routes
- Newbuild and replacement
- Port and starboard geometry confirmed
Bronze Rudder Assemblies
Cast bronze rudder and trunk arrangements for compatible vessel and installation requirements.
- One-piece casting routes
- Gunmetal trunk components
- Grease provision where specified
GRP Rudder Trunks
GRP trunk arrangements considered where compatible with the hull, rudder stock, bearings and structure.
- Composite hull integration
- Structural support required
- Stock and bearing interfaces checked
Transom Rudders
Transom-mounted solutions reviewed from vessel geometry, mounting structure, blade position and steering linkage.
- Mounting structure reviewed
- Blade and stock geometry confirmed
- Steering connection matched
RUDDER INTERFACES
The rudder, steering system and propeller arrangement must agree.
Clearance, stock, bearings, tiller or steering connection and the hull support arrangement are reviewed as connected elements.
Newbuild information
The best starting point is the vessel and steering arrangement drawing.
- Hull and propeller layout
- Rudder stock and blade envelope
- Steering travel and tiller connection
Replacement information
Photographs help identify the arrangement but do not replace verified dimensions.
- Existing drawing or survey
- Damage and operating history
- Bearing, trunk and seal details

PROJECT PROCESS
A clear route from enquiry to coordinated supply.
Custom and replacement propulsion equipment benefits from documented technical checkpoints.
PROCESS
1. Send the project data
Share vessel, machinery, dimensions, photos, drawings and required scope.
PROCESS
2. Clarify the interfaces
ERBA Marine identifies missing inputs and checks connected components.
PROCESS
3. Confirm the proposal
Configuration, materials, documentation, commercial terms and delivery are agreed.
PROCESS
4. Coordinate supply
ERBA Marine remains the customer-facing contact through the confirmed supply scope.
Important: Published examples describe available solution routes. Final dimensions, materials, tolerances, class or inspection scope, price and delivery are confirmed only in ERBA Marine’s written quotation.
FREQUENTLY ASKED QUESTIONS
Rudder Assemblies FAQs
Practical answers for selection, replacement and project planning.
Yes, subject to dimensional and technical review. An existing drawing is preferred; otherwise provide a verified survey, clear photographs and details of the stock, bearings and steering connection.
Material depends on hull, existing installation, rudder construction, operating duty and project requirements. ERBA Marine coordinates the appropriate route after reviewing vessel data.
Yes. The enquiry must identify the shaft and rudder arrangement, rotations, steering linkage and required port or starboard configuration.
Yes, when they form part of the requested scope. Stock diameter, bearing positions, trunk dimensions and sealing details should be supplied.
Photographs help identify the arrangement but are rarely sufficient for production. Verified dimensions or an approved drawing are normally required.
PROJECT-SPECIFIC ENQUIRY
Request an ERBA Marine Rudder Assemblies review.
Send the strongest available technical information. ERBA Marine will review the requirement and identify any missing dimensions or interfaces before quotation.
- Attach drawings and clear photographs.
- State known dimensions and operating concerns.
- Declare class, inspection or documentation needs early.
- Final scope is confirmed in writing before supply.
