In Atlantic City, a Viking 48 sportfishing boat once known for its powerhouse Scania diesels got a green twist—running on RD99, a 100% renewable diesel. Despite the fuel’s rarity on the East Coast, the test showed near-identical performance to conventional diesel with cleaner emissions and environmental perks. Viking Yachts and Mack Boring hope this sea trial sparks wider adoption of sustainable fuels in boating—proof that performance and sustainability can coexist.
