Emerald

In 1913 Henri Willem de Voogt, born in 1892, opened the Haarlemsche Jachtwerf on the river Spaarne in Haarlem. Feadship dates De Voogt Naval Architects, its in-house design and naval architecture studio, to that year. He designed the 54.30-metre Chahsevar for the Shah of Persia in 1936, and he joined Feadship soon after it was formed in 1949. His son Frits gradually took over design leadership from 1958, and Henri stayed involved until his death in 1963. Frits drew the 35.25-metre Camargo IV (1960), the largest Feadship of her time. From 1993 he handed day-to-day leadership to Hugo van Wieringen. The studio, now at Capellalaan 21-37 in Hoofddorp, introduced YETI, the Yacht Environmental Transparency Index, in 2019. Two Feadships we list carry its name. Emerald, a 50.4-metre Feadship from 1990, has exterior lines by De Voogt Naval Architects. Bluemar II, a 38.5-metre Feadship from 1978, has interiors credited to De Voogt.

Frank Mulder was 28 when he opened Mulder Design in 1979. He had worked at Amels and led Damen Group's high-speed vessel programme. The studio is based at Schweitzerlaan 62, Amstelveen. His son Bas joined in 2000 and became a full partner in 2008. He has led the studio since Frank stepped down in 2022, and more than 1,000 of its designs have been built. Mulder Design produced the naval architecture of the 43.59-metre Octopussy, delivered by Heesen in 1988. The studio says she reached 53.17 knots. It also produced the naval architecture of the 69.3-metre Spectre, delivered by Benetti in 2018. The studio lists her as a World Superyacht Award winner for Best Displacement Motor Yacht.

Before Design Unlimited, Mark Tucker worked at Camper & Nicholsons as an interior design specialist and at Ken Freivokh Design as an associate partner. He founded the studio with Julie Tucker in 2000. It is based in Wallington, Fareham, in the UK, and it also takes on residential interiors. Its yacht work covers interiors and exterior styling for both sail and motor, and it works with production brands including Sunseeker, Arksen and Windy. Its interior for the 46.7-metre explorer King Benji, delivered by Dunya Yachts in 2024, won Best Interior Design (motor yachts, 499GT and below, 40m and above) at the 2025 BOAT Design & Innovation Awards. Its earlier awards include Best Refit for Feadship's Mirage in 2016. Emerald, the 50.4-metre Feadship of 1990, has a completely new interior by Design Unlimited.
