Mae mordwyo yn y Bae ei hun yn gymharol ddiffwdan. Ond dylai morwyr nodi, oherwydd y posibilrwydd o gerrynt cryf o flaen llifddorau\u2019r morglawdd, y dylai cychod gadw at ochr gywir Marc Ban y Gorllewin, hy ochr yr afon\/bae o\u2019r marc.<\/p>\n

Pont y Werin<\/h4>\n

Lleolir Pont y Werin tua hanner ffordd ar hyd angorfa Marina Caerdydd.<\/p>\n

Mae’r bont yn rhychwantu afon El\u00e1i, gan gysylltu Caerdydd a Bro Morgannwg ar gyfer cerddwyr a beicwyr. Mae\u2019r rhan ganol yn codi i gychod fynd heibio.

  1. Gall cychod fynd dan y bont pan mae hi’n isel os oes digon o le rhwng ei gwaelod a phen uchaf y cwch.<\/li>\n
  2. Pan mae\u2019r tri golau coch wedi diffodd bob pen i\u2019r bont, gallwch deithio ymlaen. Meistr y cwch fydd bob tro yn penderfynu teithio ymlaen ai peidio. Mae byrddau uchdwr cychod ar ddwy ochr y bont (gydag ac yn groes i’r lli) er mwyn helpu’r morwyr benderfynu mynd oddi dani ai peidio.<\/li>\n

    1. Wrth baratoi agor neu gau’r bont, bydd y golau ar naill ochr i’r sianel (gydag ac yn groes i’r lli) yn goch cyson – yn dweud na ddylai cychod deithio ymlaen.<\/li>\n

      Cynghorir morwyr i roi rhybudd da i Reoli Morglawdd o’u bwriad i lywio o dan y bont, fel y gellir cynllunio’r lifft yn ystod cyfnodau prysur o weithredu.<\/p>\n

      Gofynnir hefyd i Forwyr gadw golwg ar VHF 18 bob amser, rhag ofn y bydd angen eu hysbysu am unrhyw newid i’r amserlen.<\/p>\n
