For example you would not say at first glance that Northern Slavs had strong naval traditions, but Pomeranian prince Ratibor I made few succesful naval invasions in XII century against Denmark, when he sacked and burned down their capital at Roskilde and when he landed huge naval invasion (650 ships according to Pomeranian sources and 780 according to Snorri Sturluson, probably both exaggarated, but even if only half of them were real, it was still impressive!) when he sacked Kungahälla.
