Our services
Custom boat design, stability compliance, and plan digitalization — engineered with precision, style, and real-world performance in mind.
We turn your ideas into clean, efficient, and build-friendly boats. Whether you need a simple, elegant hull or a complete technical package ready for the shipyard, we design vessels that are beautiful, functional, and easy to build.
Full stability assessments to ISO 12217 — hydrostatic analysis, GZ curves, downflooding points, loading conditions, and compliance checks. Monohull, multihull, planing, or displacement: calculations shipyards and authorities can trust.
We convert old paper drawings and outdated CAD files into clean, accurate digital plans — rebuilt in 2D or 3D, compatible with Rhino, AutoCAD, and other naval-engineering tools. Faster, safer, and organized for future certification work.
Software
Desktop scantling-calculation software built on ISO 12215 — designed and engineered in-house for naval architects who need fast, trustworthy plate and stiffener sizing.
CE Edition · monohull
A streamlined tool for monohull scantling calculations under ISO 12215‑5, built for quick CE-category sizing of panels, bulkheads, and stiffeners.
Completo Edition · multihull-capable
The full engine, extended to multihulls under ISO 12215‑7 — complete scantling reports for panels, bulkheads, stiffeners, and longitudinal frames.
Bundle · both editions
Both licenses together — monohull sizing and the full multihull-capable engine, in one bundle.
See it in action
Every calculation traces back to the exact ISO 12215 clause it comes from — panels, bulkheads, tanks, and stiffeners, with clear pass/fail results exported to Excel and PDF in one click.
Sample output — 10.6 m catamaran, hand-laid FRP
