Chart No. 1 · K 25
Wreck, masts only visible
Dangers
Only the masts of this wreck show above chart datum — the hull is a hidden hazard below.
What it means
Charted where only the mast(s) of a wreck are visible at chart datum, usually with a legend such as 'Masts'. The hull lies unseen beneath.
Why it matters
The visible masts mark the spot but not the extent — the hull, rigging, and debris spread around them. Pass well clear rather than steering close to 'have a look'.
