J&J Design – Yacht Design Studio

J&J Design is a yacht design and naval architecture studio founded in 1983 by brothers Japec and Jernej Jakopin in Ljubljana, Slovenia. The studio covers the full development of power and sailing boats from 20 to 80 feet: concept, naval architecture, exterior and interior design, structural engineering, production process design, prototyping and mould tooling.

Its early designs were for sailboat builders including Elan, Jeanneau and Bavaria.
