I have traded a boat for an Ericson MK2 built in 1976, number 206 in the production line. The guy who traded the boat to me didn't have any information about the boat and i got it in the dead of winter. I am looking for some help on setting up the boom and pulleys for the main sail. There are two sets of rope attached to double blocks (one with 1/4" rope and one with 1/2"). I am having trouble figuring out where these all attach. Also there is a stop that slides into the channel the main sail slides into, does this go into the mast before or after the boom is slid into the mast? Any help will be greatly appreciated and pictures would be amazing. Thank you
