SeabedCore
The italic abbreviation S identifies a sand seabed.
What it means
An italic S printed in the water area records sand at the surveyed seabed position. Qualifiers such as fS or cS may describe fine or coarse sand.
Why it matters
Sand can provide good holding, but holding also depends on layer depth, compaction, slope, anchor type, and conditions.
