Hi All, can anyone point me to a picture or diagram of how the main yard hoisting tackle on a 18c ship was attached at the deck. I can find loads of photos of the top end at the crosstrees but nothing at deck level. I am trying to scratch build HMS Mordaunt (my version LOL) using pictures and what plans I can find on the net but it is not clear how they work. The "posts" either end of the pin rails in front of the mast show two pulleys at the base so I assume a double sheave block would be above it. But as the pin rail protrudes over one side, wouldn't this foul on the tackle, or am I missing something.
