Custom Design & Engineering Support
From simple leaning post frames to complex integrated seating systems with storage, our engineering team evaluates your requirements for ergonomics, load distribution, and manufacturability.
We work directly with your CAD models to optimize frame geometry, mounting interfaces, and integrated features like rod holders, tackle storage, and drainage systems.
- Ergonomic frame design for seated and standing positions
- Load path analysis for maximum occupant safety
- Storage integration and drainage system planning
- Material & finishing selection for marine environments

Work Samples
Representative examples of our seating and leaning post fabrication. These samples showcase precision tube bending, welding, and integrated feature installation.
Precision Tube Fabrication & Welding
Integrated CNC tube bending, laser cutting, welding, and assembly in one facility. Every frame is built to precise tolerances and tested for structural integrity before shipment.
CNC Tube Bending
Mandrel-supported bending for 316 stainless and 6061-T6 aluminum tubes. Typical tolerances ±0.3–0.8 mm depending on diameter and bend complexity.
Welding & Assembly
TIG/MIG welding with fixture-controlled alignment. Assembly tolerances ±0.5–1.0 mm confirmed at quote based on joint configuration.
Laser Tube Cutting
Precision cutting with holes, slots, and miters in one setup. Tolerances ±0.05–0.1 mm for feature accuracy.
Materials & Integrated Features
Material Selection
Choose from marine-grade stainless steel (316/304) or lightweight aluminum (6061-T6/5083) with professional surface finishing for long-term durability in saltwater environments.
- 316 Stainless Steel — Maximum corrosion resistance for saltwater and offshore use
- 304 Stainless Steel — Cost-effective option for protected marine environments
- 6061-T6 Aluminum — Lightweight construction with excellent strength-to-weight ratio
- 5083 Marine Aluminum — Superior saltwater corrosion resistance for critical applications
Integrated Features
We design mounting points, drilling provisions, and integrated features directly into the frame structure.
- Integrated tackle storage compartments with drainage
- Rod holder mounting provisions and cleat integration
- Live well plumbing interfaces and through-hull connections
- Swivel or pedestal base mounting systems for helm seating
All features are optimized for manufacturing efficiency and easy installation on your vessel.
