The inaccuracies on the cards could theoretically lead to boats going aground which, in certain circumstances, could lead to risk of personal injury.
In certain waters, there are potential inaccuracies in the way that the products’ charting presents depth contours and depth areas, resulting in the depiction of water depth as deeper than the actual depth under certain display conditions.
