Schip en Werf de Zee Maritime

What Schip en Werf de Zee Maritime does

Schip en Werf de Zee Maritime, operating as SWZ|Maritime, is a Dutch-language maritime trade publication owned by the non-profit Stichting Schip en Werf de Zee (SWZ Foundation) and headquartered in Rotterdam. Founded in 1948 and rebranded to SWZ|Maritime in 2019, it has been a leading Dutch brand for maritime technical professionals for over 75 years. Its editorial coverage spans ship design, shipbuilding, propulsion, offshore equipment, maritime research, naval procurement, and emerging areas such as uncrewed systems and alternative marine fuels.

The core product is an 11-issues-per-year print magazine, complemented by a daily-updated WordPress-based website (swzmaritime.nl), a weekly Thursday email newsletter, a digital archive (SWZ–Akerboom) dating to 1919 accessible via web and mobile app, and event coverage of major maritime conferences. The publishing operation — including subscription fulfillment, customer service, and advertising sales — is outsourced to Mybusinessmedia in Deventer, while editorial staff remain in Rotterdam.

Revenue is generated through three streams: annual subscriptions (€179/year domestic, €260/year international, plus discounted or bundled tiers via KNVTS, Nautilus International, and NVKK memberships); advertising across print, web, and newsletter (sold through Mybusinessmedia); and membership fees via KNVTS (€120/year regular, €60 junior, €20 student). Distribution is anchored by governance and partnership ties to KNVTS, Stichting de Zee, MARIN, NMT, KIVI, and CEDA, giving the publication an embedded position within the Dutch maritime engineering community.
