The correct answer is D) Ensure extra tucks are taken in the splice. When splicing nylon line, it is important to ensure that extra tucks are taken in the splice to create a stronger and more secure connection. This is because nylon is a relatively smooth and slippery material, which can make it more challenging to create a solid splice compared to other types of rope. Taking extra tucks in the splice helps to lock the strands in place and prevent the splice from coming undone over time. The other answer choices are incorrect because: A) Short splices can be used in nylon line, but they may not be as strong as a long splice; B) Long splices are generally preferred for nylon line, but extra tucks are still important; and C) While using a thimble can help to reinforce the splice, it is not an absolute requirement for nylon line.
