I purchased a 78 Lancer 28 two years ago. It was in rough shape. I have been slowly refurbing it. It did not come with a main sheet track, traveler or car set up. It also did not come with a Boom Vang. I am getting ready to put it in the water and need to aquire those two systems. I believe this boat originally was set up to have the main sheet attached to the step leading into the Cabin. I have seen pictures of set ups on the cabin roof. Can anyone provide close up pictures of how those systems are assembled and suggestions on MFG?
