Boat Hull Bottom – Corrugated Sandwich

Create a detailed 3D CAD model of a boat hull bottom for HDPE PE100 construction. Overall dimensions: Length 7400 mm. Width at stern 2600 mm. Symmetrical about centerline. Hull shape: The aft 4900 mm of the hull bottom is flat across the width. From 4900 mm forward, gradually transition into the bow. Hull width reduces smoothly toward the bow. Bow section has a 25-degree V-bottom angle. Transom is flat and vertical. Bow ends in a sharp centerline stem. Smooth curvature transitions throughout. Sandwich construction: Outer skin thickness 10 mm. Inner skin thickness 10 mm. Corrugated core wall thickness 10 mm. Entire assembly fused into one watertight solid body. Corrugated core: Longitudinal corrugations running from stern to bow. Trapezoidal corrugation profile. Continuous bonding to both skins. Smoothly varying geometry along hull length. At stern: Corrugation height 250 mm. Corrugation spacing 200 mm center-to-center. Toward bow: Gradually reduce corrugation height. At bow: Corrugation height 70 mm. Corrugation spacing 150 mm center-to-center. Corrugation profile: Wall thickness 10 mm. Side wall angle 60 degrees. Top and bottom flat sections. Root fillet radius 20 mm. Crown fillet radius 20 mm. Surface details: Maintain constant material thickness everywhere. Add 15 mm fillets where corrugations connect to skins. Preserve smooth transitions between flat stern section and V-shaped bow section. Output requirements: Generate one closed manifold solid body. Suitable for STEP export. Suitable for large-scale HDPE 3D printing. Show full internal corrugated structure. No gaps, overlaps, or self-intersections. High geometric accuracy.
