A ship anchored in a port has a ladder where the bottom of tave touches the water?

If a ship is anchored in a port and has a ladder where the bottom touches the water, the ladder is likely submerged to some extent depending on the tide and the ship's position. As the water level changes with the tide, the height of the ladder above the water may also change, but the bottom will remain in contact with the water. This setup allows crew members to board or disembark the ship easily.
