About Shortack
Who We Are
Shortack is an independent naval architecture and marine technical support group serving yacht, workboat, and maritime infrastructure programs.
We operate as a distributed team of experienced naval architects, engineers and technical specialists with deep backgrounds in composite structures, aluminum vessels, shipyard support and production documentation. Collectively, our team brings more than a century of combined marine industry experience across Europe and North America.
Our focus is straightforward: disciplined engineering, practical documentation, and reliable delivery under real program constraints.
Our Team
Shortack operates as a distributed group of naval architects, engineers and technical specialists with experience across composite yacht construction, aluminum workboats and industrial marine structures.
Our team includes professionals with backgrounds in:
Large-scale composite yacht programs
Coast Guard and class-certified vessels
Structural analysis and laminate development
Production drawing development and shipyard technical office support
We assemble teams based on program requirements, maintaining flexibility while ensuring senior-level oversight on all deliverables.
Our Background
Shortack was formed to provide high-level naval architecture and technical office capability without the overhead of a traditional large consultancy.
Our work spans:
Custom and production yachts
Small passenger and patrol vessels
Aluminum and composite structures
Shipyard technical office reinforcement
Industrial marine and infrastructure projects
We have supported programs ranging from early concept development through class approval, certification and production-phase execution.
Our experience includes composite structural development, stability analysis, production drawing generation, CNC-ready output, documentation control alignment, and fabrication support.
We are equally comfortable working alongside established technical offices or leading defined engineering packages directly.
How We Work
Shortack integrates into existing teams.
We understand that active marine programs are rarely linear. Schedules compress. Scope evolves. Documentation must align with class, flag and yard sequencing. We operate within those realities — reinforcing internal teams without disrupting established workflows.
Engagements are structured, scoped and accountable. Deliverables are aligned with production requirements, not theoretical output.
We are remote by design, allowing us to support shipyards and design offices on both sides of the Atlantic with efficient turnaround and controlled overhead.
The Name
The name Shortack comes from sailing.
A “short tack” is a maneuver used when working upwind in confined water — when space is limited and conditions demand precision. It requires timing, awareness, and disciplined execution.
The name reflects how we approach projects:
Clear direction. Controlled movement. Measured response under pressure.
Continuity & Mentorship
Shortack builds on decades of experience in naval architecture, composite development and marine engineering.
We are shaped by the mentorship of respected naval architects and engineers who dedicated their careers to disciplined structural design and integrity in marine construction. Their influence continues in how we approach analysis, documentation and professional conduct.
Our foundation is technical rigor, long-view thinking, and respect for the craft.
What Clients Can Expect
Clients working with Shortack can expect:
Clear communication
Structured deliverables
Technical depth without unnecessary complexity
Respect for schedule and production realities
Alignment with class and regulatory frameworks
We are not a volume consultancy. We take on programs where disciplined engineering makes a measurable difference.
Founders
Shortack was founded by naval architects with backgrounds in high-performance yacht development, composite structures and shipyard-based technical office operations.
The firm is led by professionals whose experience spans custom and production yacht programs, composite structural development, aluminum vessel engineering and industrial marine support across Europe and North America.
Senior leadership remains directly involved in all projects, ensuring technical continuity and disciplined engineering oversight from concept through delivery.
René Lange
Ocean & Naval Architectural Engineer, B.Eng., 2006, Memorial University of Newfoundland & Labrador, Canada
René founded Shortack in February 2022. His 20+ year career spans high-performance composite yacht programs, large custom builds, autonomous surface vessels and industrial marine projects. His background combines structural development, composite engineering and production-phase technical office coordination under demanding build schedules.
He has worked across Europe, North America, Australia, New Zealand and others in both yard-based, design and consultancy roles, with a focus on practical, build-ready engineering output.
Rodrigo Nisi
Naval Architecture Degree, 2016, Universidad Nacional de Quilmes, Argentina
A co-founder brings experience from advanced composite racing yacht programs, including involvement in elite international performance campaigns and large-scale composite construction environments. His background includes technical roles within leading European shipyards and participation in high-performance development programs at the forefront of modern sailing design.
He later joined Shortack to focus on applied naval architecture and composite structural development within active build programs.
