Understand the reference behind a forecast or anchoring discussion. Wave statistics, tidal levels and anchoring dimensions each need context; no glossary entry is a go-or-no-go decision.

Also find under: rode
The chain, rope or combination connecting the vessel to its anchor.
A rode description should identify the components and their compatibility with the anchoring equipment.
Also find under: kn knots kt
A speed of one nautical mile per hour.
A knot is a speed unit here, not a rope fastening. Ten knots means ten nautical miles per hour.
A tide occurring in the part of the cycle generally associated with smaller tidal ranges.
Neap does not mean no tidal movement, current or navigational risk.
Also find under: anchor scope
In anchoring, the ratio of rode deployed to the vertical distance from its attachment point to the seabed.
State the reference height and tidal allowance when discussing scope; this is not a universal deployment recommendation.
Also find under: wind waves seas
Waves generated by winds acting locally over the water.
A forecast may report sea waves separately from swell; read both and their combined implications.
Also find under: Hs combined sea and swell
A statistical wave-height measure approximately representing the average height of the highest third of waves.
It is not the maximum individual wave; larger waves can occur.
Also find under: anchor snubber
An elastic line or arrangement used to soften loads, commonly in an anchoring setup.
Its length, material and attachment need to suit the actual arrangement; a definition is not a sizing instruction.
A tide occurring in the part of the cycle generally associated with larger tidal ranges.
The name is related to the tidal cycle, not the season of spring.
Waves that have travelled beyond their generating wind area, or persist after that wind has eased.
Calm local wind does not establish an absence of swell.
The difference in water level between a high tide and a low tide under the stated comparison.
A tidal range is not the same as the depth available at a specific moment.
Also find under: TWS TWA
Wind relative to a stated reference frame after accounting for the effect of vessel motion.
Marine instruments may use water- or ground-referenced calculations; check the source before comparing values.
Also find under: swell period
The time between successive wave crests passing a point, under the particular period measure used.
Check whether a forecast means peak or another period measure before comparing numbers.
