Hi. I see it has been a while since your original post, but I have similar questions about Columbus' ships. I decided to build the Heller Nina after not having built a sailing ship for many years. I was wondering if the ships used by Columbus even used deadeyes. More generally, when did ships begin using deadeyes?
Also, the anchors in the Heller Nina look like something that came off of a large 18th century ship. I don't know what anchors looked like in Columbus' day, but I have a feeling they don't look like what came in the box with the kit.
And when did the practice of coating standing rigging with tar begin?
Perhaps some more knowledgeable about these these can supply some answers.
