Question 2518 Deck General

The correct answer is A) shackle secured with a nut and cotter pin. The connection to the towline must be secured with a shackle that is secured with a nut and cotter pin. This is the industry standard and regulatory requirement for securing a towline connection, as it provides a strong, reliable, and tamper-resistant connection. The other options are incorrect because: B) a galvanized screw-pin shackle may not be secure enough, C) a shackle with a swivel piece is not the standard, and D) a hardened steel thimble is used to protect the line, not to secure the connection.
