My original equipment mainsheet is 5/8″, hanging on the wall in my garage. I’ve since replaced it. Anything 1/2″ or larger should work just fine. Larger line is easier to handle and easier on the hands.
I’ve since replaced the three blocks on the boom with Garehauer blocks. These ball-bearing blocks have lower friction and make the main easier to trim. IMHO, they make the best stuff out there and they are very cost effective. I haven’t replaced the two deck-mounted blocks, the cheek-block and stand-up block, because they would be a PIA to replace.
