Kanal Vela Vrata
Le canal est profond et clair, le fond étant formé de boue.
Kvarner, the W and widest channel, leads from the open Adriatic Sea end enters the basin via Kanal Vela Vrata.
Kvarneric, the middle channel, leads through Srednja Vrata into the basin. This channel is connected at its S end to the N end of Zadarski Kanal and to the open sea by Kvarnericka Vrata.
Velebitski Kanal, the E channel, is long and narrow and lies close W of the mainland. It is separated from Kvarneric to the W by several large islands. This channel leads through Vinodolski Kanal and Tihi Kanal at its N end and enters the NE head of the basin.
There are numerous anchorages for small craft along both shores of the N part of this channel. However, as there is little shelter for large vessels, this part of the channel is generally avoided during the late autumn and winter. At such times, large vessels proceed to Rijecki Zaliv via Srednja Vrata or Kvarner.
