Hello all, I recently purchased a 1973 e 27 and have a few questions. I got the boat for a song $500, And i joined the yacht club i bought it form (also very reasonable). The boat is equipeed with a roller fuler and a 150 genoa, and a standard mainsail. I noticed there appears to be a block on the backstay to add tension. What do you call this and when would i need it? does the jib require a block or can you sail without it? (the rails are empty) This is an inboard model converted to outboard, will a 25' SHAFT WORK RIGHT ON THE TRANSOM? OR DO I NEED TO HAVE A BRACKET? thanx in advance for your input.
