Chart Datum
Chart Datum (CD) is a level set low enough to ensure that the tide rarely falls below it. The UK usually determines this as being approximately the level of Lowest Astronomical Tide. In effect, this is the minimum depth that can be achieved by a quayside or port entrance channel.
Datwm Siart
Mae Datwm Siart (CD) yn lefel a osodir yn ddigon isel i sicrhau mai anaml iawn fydd y llanw yn disgyn oddi tano. Mae'r DU yn diffinio hyn fel arfer fel tua lefel y Llanw Seryddol Isaf. Mewn gwirionedd, dyma'r dyfnder lleiaf y gellir ei gyflawni gan lan y cei neu sianel mynedfa porthladd.
Vessel Dimensions
Length overall (LOA) means the maximum length of a vessel's hull when measured parallel to the waterline.
A ship’s beam refers to its width at the widest point, when measured at the ship's nominal waterline.
The draft of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel), which includes the thickness of the hull. The draft of a ship or boat signifies the minimum depth of water it can safely navigate.
Dimensiynau Llongau
Mae cyfanswm hyd (LOA) yn golygu uchafswm hyd corff llong pan fesurir hynny yn gyfochrog â llinell y dŵr.
Mae lled llong yn cyfeirio at ei lled yn y rhan lletaf, pan fesurir hynny wrth linell dŵr nominal y llong.
Dyfnder corff llong yw'r pellter fertigol rhwng llinell y dŵr a gwaelod corff y llong (cêl), sy'n cynnwys trwch corff y llong. Mae dyfnder cwch neu long yn nodi isafswm dyfnder y dŵr y gall ei fordwyo'n ddiogel.
