Yachts & Small Passenger Vessels

Naval architecture and technical project support for custom yachts and small passenger vessel programs.

Shortack supports new-build and refit yacht and small passenger vessel programs requiring disciplined naval architecture, structural development, stability compliance, and performance-oriented analysis.

Whether supporting full design development or reinforcing specific technical packages, our focus remains practical execution and defensible engineering decisions.

New Build Yacht Design

Full naval architecture development from concept refinement through stability documentation and certification coordination.

Refit & Redesign

Structural modification, weight control, systems upgrades, and performance-driven redesign for vessels undergoing refit or scope expansion.

Concept Development & Feasibility

Early-stage hull form studies, stability modeling, and technical risk evaluation supporting investment and program definition decisions.

Stability & Certification

Intact and damage stability development, weight and center-of-gravity control, and coordination with class and flag requirements for compliant and defensible vessel operation.

Owner Advisory & Support

Independent naval architecture support for owner-driven programs requiring structured review and technical coordination.

U.S. Coast Guard Subchapter T & Small Passenger Vessels

Naval architecture support for U.S. Coast Guard Subchapter T passenger vessel programs, including stability documentation, structural verification, weight control, and regulatory coordination. Work is aligned with inspection requirements and operational realities to ensure compliant, buildable outcomes.

Performance & Seakeeping Studies

Resistance prediction, propulsion integration, motion response evaluation, and feasibility studies supporting performance-sensitive yacht and passenger vessel programs.
