Aluminium small boat (Tinny) Design

PROJECT OBJECTIVE Design a simple, easy-to-weld aluminum fishing boat modeled on proven designs like Alublack. The boat must be buildable by a DIYer with basic welding skills, using straight aluminum sheet with minimal forming, and light enough to roof-mount on a Land Cruiser. Reference style: Flat-sided, V-bottom fishing dinghy (see attached Alublack images) PROJECT SCOPE What I need: Simple 3D Hull Model in Fusion 360 Straight flat sides (port & starboard) V-shaped bottom (simple angle, not complex curve) Vertical bow panel Vertical transom (engine mount) No ribbing, no formed/rolled panels Flat Panel Cutting Drawings (DXF files) Bottom V panel (two flat sheets meeting at angle for V-shape) Port side (single flat sheet) Starboard side (single flat sheet) Bow panel (flat) Transom panel (flat) Chine/edge strips (angle iron or flat bar) Simple Assembly Drawing Top-down layout Side profile showing V-bottom angle All dimensions for cutting/welding Weld line locations NOT needed: Curves or compound surfaces Ribbing or structural details Interior design Any complex forming or bending BOAT SPECIFICATIONS Size: Length: 3.9m max Width (beam): 1.7m max Depth (inside): 0.6m Draft: 0.35m Hull Design: Sides: Straight flat aluminum sheets Bottom: V-shaped (simple angled panels, angle TBD by designer) Bow & Transom: Vertical flat panels No curves, no flaring, no ribbing Weight: 110-130kg (roof-mountable) Engine: 9.9-15hp outboard Material: 3mm aluminum sheet sides/ends, angle iron for chines Use: Rivers, lagoons, coastal estuaries (fishing/camping) DESIGN PRIORITIES ✅ Flat aluminum sheets — No bending or forming needed ✅ Straight lines — Minimal cuts, easy welding ✅ V-bottom from flat sheets — Two angled panels, simple joint ✅ Light & portable — Fits roof racks ✅ Basic tools only — MIG welder, plasma cutter, grinder ✅ Fast to build — ~4-6 weeks DIY welding ❌ NOT concerned with: Curves, fancy design, performance, flared bow PROJECT DELIVERABLES Fusion 360 File: Alublack_Style_3.9m_Model.f3d DXF Cutting Files (1:1 scale, millimeters): Tinny_Bottom_V_Panel_Left.dxf — Left V-bottom sheet Tinny_Bottom_V_Panel_Right.dxf — Right V-bottom sheet Tinny_Port_Side.dxf — Port flat sheet Tinny_Starboard_Side.dxf — Starboard flat sheet Tinny_Bow_Panel.dxf — Bow end (flat) Tinny_Transom_Panel.dxf — Engine transom (flat) Tinny_Chine_Strips.dxf — Angle iron/flat bar edges PDF Drawings: Tinny_Side_Profile.pdf — V-bottom angle, dimensions Tinny_Top_View.pdf — Layout, beam width Tinny_End_Views.pdf — Bow & transom shapes Tinny_Assembly_Guide.pdf — Weld locations, sequence Material List (Excel): Sheet sizes & quantities Angle iron lengths Cutting efficiency notes BUDGET Total: USD $150 (approx ZAR 2,800) NOTES FOR FREELANCER Reference: See attached Alublack boat photos — same style/simplicity Priority: Build-ability over performance Materials: Flat sheet aluminum only (no formed panels, no ribbing) Target audience: DIY welder in home garage Tools: MIG welder, angle grinder, plasma cutter (basic only)
