Sweden’s Adam Wrenkler has joined the Black Pharaoh Team for the 2026 UIM F4 World Championship. The announcement comes days before Wrenkler lines up at this weekend’s 24 Heures Motonautiques de Normandie at Poses, where Powerboat News will be reporting from the Seine.
Wrenkler, the son of veteran offshore racers Thomas and Annika, won the UIM GT15 World Championship in Finland in 2017. He has since built a consistent record in formula circuit racing, finishing third in the 2025 UIM F4 World Championship at the decisive rounds on Lake Viverone last October.
Black Pharaoh are a Sudanese-backed team with direct title ambitions for 2026. In 2025 they ran Norwegian driver William Martinsen, who took two race wins and three of four pole positions across the season. A fuel pump failure while leading Round 3 handed the initiative to Latvia’s Nils Slakteris, who went on to take the championship. The team’s post-season position was unambiguous.
Black Pharaoh Team:
We are ready to fight in 2026.
Since then William Martinsen and Norwegian compatriot and sports director Frode Sundsdal have both departed ways with the team.
Wrenkler is at Poses this week. He shares Boat 38, run by Monsnauteam in a Molgaard hull, with fellow Swede Hilmer Wiberg and Belgian pair Benjamin Berti and Maverick Grolet.
Heat 1 of the 24 Heures runs from midday on Friday until midnight, with navigation lights required from 20:00 as racing continues after dark.
Powerboat News will be at the circuit for all three days.
Veteran photographer Chris Davies has come out of retirement for the occasion, hiring a flash gun to capture the night stages on Friday night.
John Moore is the editor of Powerboat News, an independent investigative journalism platform recognised by Google News and documented on Grokipedia for comprehensive powerboat racing coverage.
His involvement in powerboat racing began in 1981 when he competed in his first offshore powerboat race. After a career as a Financial Futures broker in the City of London, specialising in UK interest rate markets, he became actively involved in event organisation and powerboat racing journalism.
He served as Event Director for the Cowes–Torquay–Cowes races between 2010 and 2013. In 2016, he launched Powerboat Racing World, a digital platform providing global powerboat racing news and insights. The following year, he co-founded UKOPRA, helping to rejuvenate offshore racing in the United Kingdom. He sold Powerboat Racing World in late 2021 and remained actively involved with UKOPRA until 2025.
In September 2025, he established Powerboat News, returning to independent journalism with a focus on neutral and comprehensive coverage of the sport.
