Attach hull panels: Rivet or weld panels to the frame securely.
Seal seams: Apply marine-grade sealant where necessary to ensure watertightness.

4. Interior Fittings

Install seats and benches: According to preference and blueprint guidance.
Add flotation chambers: For added safety if recommended.
Mount hardware: Cleats, handles, and motor mount brackets.

5. Final Finishing

Sanding and polishing: Smooth edges and surfaces to prevent injury and enhance appearance.
Painting or coating: Optional protective layers or camouflage for hunting.
