MDSL | Marine Designers

MDSL provides focused technical design services to naval architects, marine engineers, and boat builders. Led by principal designer Simon Daly, the consultancy transforms complex structural ideas into practical production drawings, 3D models, and construction plans tailored for sailing yachts and motorboats.

High-end composite engineering underpins much of the work done by MDSL. Building on Daly’s extensive background designing carbon spars and composite components for major rig producers like Southern Spars, the company brings deep knowledge of lightweight structural design directly to custom and production yacht projects.

Collaboration with yards and engineering teams covers a wide range of needs, from individual component design to detailed structural plans. Every drawing package emphasizes practical assembly techniques, structural efficiency, and the seamless alignment of hulls, rigs, and internal framing.

Drawing strength from New Zealand’s long-standing reputation in yachting innovation, MDSL serves as an adaptable technical resource. The company steps into projects at any stage, delivering detailed documentation that bridges the gap between conceptual naval architecture and physical boatbuilding.
