Hi, I'm Osman Ender Kalender, a Naval Architect (MSc) based in the Netherlands with 15+ years of experience in yacht design, commercial vessels, workboats, small craft engineering, and advanced 3D modeling. My background spans Feadship, Damen Schelde Naval Shipyard, Euromarine, Sarp Yachts, and multiple R&D and concept-development roles. I specialize in solving complex marine engineering problems quickly and accurately—whether you need hydrodynamic analysis, stability, 3D vessel development, structural layouts, or professional engineering judgment for design decisions. My work combines naval architecture + 3D visualization + practical shipyard-level engineering, which gives clients a rare combination: beauty + engineering accuracy + production-ready thinking. 🔹 WHAT I DO BEST 1) Small Craft & Yacht Engineering (6–50 m) - Hull design, refinements, hydrodynamic viability - Stability, hydrostatics, trim analysis - Powering prediction & engine sizing - Weight estimation / LCG–VCG assessment - CE/RCD-inspired compliance guidance - Parasailing boats, fast craft, leisure craft, refit engineering 2) Concept-to-Model Development -Starting from a hull, sketch, or GA, I can build a full 3D marine model including: -Structural members (frames, girders, longitudinals) -Decks, bulkheads, superstructure -Machinery spaces & arrangement -Piping fundamentals (routing, logical placement) -Clean Rhino topology suitable for CNC & production -CAD drawings (DWG/2D production sheets) This is ideal for early-stage startups, boat builders, and engineering teams lacking in-house naval architecture support. 3) Fast Engineering Consultancy (48h Sprint) Short, high-impact technical tasks: Hydrodynamic viability check Recommended HP + performance prediction Weight distribution evaluation Safety/rigging/structural recommendations Quick technical memos for investors & founders Pre-survey design review for concept feasibility 🔹 TOOLS & SOFTWARE Rhino 3D (expert) – main modeling tool Maxsurf – stability, hydrostatics, powering PIAS – naval architecture tools AutoCAD – 2D drafting KeyShot / Lumion – photoreal renders Siemens NX / 3DX / Teamcenter – production-level design MS Project / PMI methodology – project planning 🔹 WHAT MAKES ME DIFFERENT? ✔ Engineering-Level Accuracy Most 3D designers are artists. I am an engineer first, ensuring proportions, hydrostatic balance, centerlines, and structure make sense in the real world. ✔ Shipyard-Ready Thinking I’ve worked inside major Dutch yards. I know what is buildable, maintainable, and safe. ✔ Clear Communication & Documentation I can deliver technical notes, short engineering memos, design justifications, and investor-friendly feasibility summaries. ✔ Fast & Iterative My workflow is ideal for clients who need progress quickly: “Share your model → I analyze → we iterate → you get clear answers.” ✔ Global Marine Perspective Hydrodynamics, weight, stability, safety—and the practical realities of operating boats—are core to how I work. 🔹 TYPES OF PROJECTS I DELIVER -3D Development Cargo ships (from hull + GA → full 3D structure) Passenger boats Parasailing vessels RIBs, tenders, chase boats Concept vessels & prototypes -Technical Guidance Stability (intact/damage overview level) Powering & performance Weight distribution plans Safety equipment selection Preliminary structural evaluation Feasibility assessments -Visualization Photorealistic renderings Concept presentation materials Environment renders (river, sea, marina) 🔹 WHO I WORK WITH Boat builders Designers & inventors Startups developing new marine products Shipyards lacking NA support Entrepreneurs validating a concept Training schools, watersports companies RYA/CE consultants needing NA input 🔹 AVAILABILITY I work less than 30 hours/week, but in high-focus blocks, ideal for clients who want fast progress and clear results. Short-term sprints or long-term recurring support available. If your project involves water, structure, performance, or the real-world behavior of marine craft — I can help. Let’s build something seaworthy together. Send your hull, 3D model, GA, or even a sketch — and I’ll take it from there. — Osman Ender Kalender Naval Architect, MSc
