Hello all! I just got an h16. I tried to setup yesterday and all went well untill I got to hooking up the mainsheet. I was using the assembly manual available online. It shows a configuration that is different from the one on my boat. My boat has two single pulleys on the boom, spaced about 6" apart. On the "lower" block there are two pulleys side-by-side and then a ratchet under that which attaches to the top of the traveler car. The diagram shows a small tab above the clam jaws where the sheet is tied before it starts it's path through the pulleys. My block does not have a place to tie here. This hardware is all labeled "seaway" Is this after market stuff? Can someone post an accurate diagram or photo of how to set this up? Thanks.
