The Royal flagship Gribshunden carried the Danish King Hans on its way to the city of Kalmar in Sweden when the ship sank in the summer of 1495. The ship caught fire while anchored north of the Stora Ekö Island and sank to the seafloor, where it lies to this day. The wreck was rediscovered in the 1970s and is remarkably well preserved. Since 2001, scientific investigations have been performed on the wreck by various organizations. In total, 13 dendrochronological samples from different parts of the ship construction have been collected and analyzed with standard dendrochronological methods with respect to age and provenance. The results show that all dated samples could have been felled during the winter season of 1482/83, although only one sample contains sapwood and waney edge. The highest correlations are obtained from reference chronologies that originate from the River Meuse drainage area, with correlations peaking around the city of Namur in Belgium. Most likely, the ship was constructed in a shipyard close to the mouth of the River Meuse in the southern Netherlands. It seems King Hans realized the potential of the new ship type represented by Gribshunden, but his shipwrights did not have the knowledge to build such a ship in Denmark. Instead, he purchased the ship from abroad. This study highlights late medieval economic and political connections throughout northern Europe.

皇家旗舰Gribshunden1495 年夏天，这艘船在前往瑞典卡尔马市的途中载着丹麦国王汉斯。这艘船在停泊在 Stora Ekö 岛以北时起火并沉入海底，直到今天。沉船在 1970 年代被重新发现，并且保存得非常完好。自 2001 年以来，各种组织对沉船进行了科学调查。总共收集了来自船舶建造不同部分的 13 个树木年代学样本，并使用标准的树木年代学方法对年龄和来源进行了分析。结果表明，尽管只有一个样品含有边材和边缘，但所有年代久远的样品都可能在 1482/83 的冬季被砍伐。最高相关性来自源自默兹河流域的参考年表，相关性在比利时那慕尔市附近达到顶峰。最有可能的是，这艘船是在靠近荷兰南部默兹河河口的造船厂建造的。汉斯国王似乎意识到了以Gribshunden，但他的造船工人不具备在​​丹麦建造这样一艘船的知识。相反，他从国外购买了这艘船。这项研究突出了整个北欧中世纪晚期的经济和政治联系。
