Line Selection by Types
You might want to check out West Marine's catalog for the type of line to use based on the type of sailing you do. However, it recommends 3/8" Sta-Set for cruising boats 26'-30' and you could go to 3/8" Sta-SetX for less stretch. If you are a die hard racer and want to get the lightest and strongest line possible, check the comparisons for the really high tech lines as you can go lighter, smaller diameter with more cost.
