I have to replace all the running rigging on the boat. *The rigging is very
worn, but it appears that the size of the lines are as follows:
Reefing lines: *3/8"
Jib Halyard: *3/8"
Main Sheet: *1/2"
Main Halyard: *3/8"
Can anyone confirm that these are the right line sizes?

Thanks for any assistance

A Google search might turn up an owners group with a online manual.
As far as replacing running rigging goes those sizes sound fine
although upgrading to a slightly higher tech line would allow you to
drop down a size in halyards particularly the jib halyard. Mainsheet
would not have to be high tech and you could still drop down to 3/8" I
use 3/8" StaSet on my boat and it has a bigger main than yours. Buy
solid black for the mainsheet.
