It is an approximately 100-meter-long embankment of blasted rock that extends from the western point of Tallholmen, in a westerly direction, towards Porsholmsskäret about 30 cm below normal water level. On the map, it looks like a localized reef within a shallower area. The most recent grounding occurred on July 13. In recent years, I have pulled off grounded boats on five occasions. Everyone thought they were clear inside or just outside the reef.
