Questões Militares de Engenharia Naval - Arquitetura naval

The spiral maneuver, as described in the book “Principles of Naval Arquitecture” (PNA), serves mainly to determine: 

The investigation into the grounding of a Russian conteiner ship, the “Kapitan Serykh”, included the following conclusions:
1. The grounding was the result of the “Kapitan Serykh” not attaining sufficient propeller thurst/speed to execute the turn on to the leads in the wind conditions at the time.
2. The exchange of information between the master and the pilot did not conform to the requirements of the International Convention on Standards of Training, Certification and Watch Keeping for Seafares.
3. For reasons unknown, the master did not provide the manoeuvring full ahead pitch, as indicated on the Pilot Card and repeatedly requested by the pilot.
4. Had the Pilot been informed of the manoeuvring problems during the vessel’s arrival at the port he would have been forewarned of a possible problem during departure.

The conclusions prove the importance of pilot-master information exchange. In order to provide the master with any information that is relevant to the vessel passage, this exchange should include:
I) providing estimated call out time for the crew, need for an anchor watch, any special engine maneuvers.
II) discussing recent changes in the International Regulations for Preventing Collisions at Sea.
III) fixing the current position and reviewing the general route from that point to the berth or anchorage.
IV) discussing any accidents recently occurred in the harbour.

According to MacElrevey & MacElrevey, in the book “Shiphandler for the Mariner”, is correct to affirm that:  

O prático Gomes assessora o comandante na condução de um NM de 250 m pelo canal de acesso a um porto, exibindo no mastro, em adriças distintas, a marca constituída por um cilindro preto, a bandeira HOTEL e a bandeira DELTA. Uma lancha de cerca de 10 m de comprimento navega em rumo aproximadamente perpendicular ao do NM, indicando visualmente que vai cruzar a sua proa de BE para BB, em situação facilmente avaliada como de risco de abalroamento. O experiente Gomes, em cumprimento ao COLREG, sugere corretamente ao comandante:  

Assinale a opção abaixo que completa corretamente as lacunas das seguintes sentenças:
A âncora é ligada ________________ à amarra, que é uma cadeia de elos especiais ________________. ________________ é a aresta saliente localizada na base inferior ________________ nas âncoras tipo ________________. 

Consulting R. S. Crenshaw, Jr., in the book “Naval Shiphandling”, in order to remember some techniques about mooring a destroyer to a buoy, a pilot made a list with the following procedures:
I) stop the engines at 200 yards from the buoy, pass the buoy line and messenger to the boat, and send the boat out ahead with the buoy line.
II) use a buoy hook for securing buoy line, as necessary.
III) never allow the ship to get between the buoy and the boat.
IV) use the engines and helm to twist the bow downwind and slightly short of the buoy, when making a buoy crosswind or crosscurrent.

From that list, is correct to affirm according to the referred book that:
