Mare Forum events are built around one principle: no boring presentations. Every conference is structured as a live debate — small rooms of 150 to 350 senior leaders, 65 to 70 percent of whom are C-suite, owners, or founders. Past speakers include the Secretary General of the International Chamber of Shipping, the Secretary for Transport of the Hong Kong SAR Government, the Secretary General of the Norwegian Shipowners' Association, and the heads of ING, ABN AMRO, Bureau Veritas, and Lloyd's Register.

Mare Forum events are the opposite of a trade show. Attendance is capped at 150 to 350 people, 65 to 70 percent of whom are C-suite, owners, or founders. There are no exhibition booths, no sponsor-driven presentations, and no keynote monologues. Every session is a live panel debate. Delegates average 80 to 150 facilitated one-to-one meetings per event — a concentration of senior interaction impossible at larger exhibitions.
No. Mare Forum and Marine Money are entirely separate organisations with no connection. Mare Forum is an independent maritime conference business founded in Rotterdam in 1999.

The Mare Forum Ship Finance conference is an annual forum held in Rotterdam in November, in conjunction with the Europort Exhibition.

It brings together shipowners, bank lenders (ING, ABN AMRO, NIBC, Hamburg Commercial Bank), leasing companies, private equity, and maritime lawyers for a full day of structured debate and networking.
Topics are driven by market conditions, not sponsor agendas. Recurring themes include: shipping capital markets and newbuild finance; decarbonisation and green shipping finance; geopolitical risk and trade route shifts; EU ETS and CII compliance; alternative fuels investment; dry bulk, tanker, container, and LNG market outlooks; and superyacht regulatory, technical, and ownership trends. All sessions are live debates between practitioners, not presentations.

The Mare Forum Ship Finance conference in Rotterdam is one of Europe’s leading independent ship finance forums, now in its 25th year. It offers a high density of C-suite attendees (65 to 70 percent) and an average of 80 to 150 facilitated one-to-one meetings per delegate. Marine Money Week in New York is the largest global ship finance gathering. Both serve different geographies and are complementary for finance professionals.
Posidonia (Athens, biennial) and Nor-Shipping (Oslo, biennial) are large maritime trade fairs with thousands of attendees and exhibition floors. Mare Forum events are small-format (150 to 350 attendees), annual, and structured around debate. They are complementary: the Ship Finance conference co-locates at Europort, and the Oslo forum runs alongside Nor-Shipping, allowing delegates to attend both in the same trip.
Key maritime conferences in 2026 include: Mare Forum Ship Finance (Rotterdam, 12 Nov, 25th edition); Mare Forum Greece (Athens); Mare Forum Oslo alongside Nor-Shipping; Posidonia (Athens, biennial); Sea Asia (Singapore); Marine Money Week (New York); and Gastech (LNG focus). Mare Forum events are best suited to senior professionals prioritising high-density C-suite networking over large-format attendance.
