At long last and after almost 3 years of projects, we are about a month away from launching our restored WS 42, Harmony!  While we won't have all of the finish varnishing done, and will more than likely continue to update items after a shakedown of our efforts this summer, we will finally get the old girl wet.

Anyway, I need to replace every bit of running rigging on our WS 42 ketch.  I have studied Bud's manual, but want to verify that I will be installing the correct size line for halyards and sheets, etc.  As Bud' manual states, the following line sizes are appropriate for the WS42:

Halyards:  Main, Staysail, Jib and Mizzen @ 7/16''

Spinnaker/Drifter Halyard:  we do not have one, but would assume the 7/16" would be the choice

Topping Lifts:  Main and Mizzen @ 7/16" - this isn't mentioned in Bud's manual, but I would assume this size or maybe 3/8"

Sheets: Main, Staysail, Jib, and Mizzen @ 1/2" - This seems a bit big for the mizzen, but want to make sure.

Thanks for the input and/or verification. 

Mike, thanks for your reply!  Our boat yard was finally able to haul the spars out to the shed and put them by the boat.  While working on the boat I looked over the masthead fittings on both the main and mizzen, and from a rough eyeball measure, I agree that 1/2 inch would work, as it does in your case.

Thanks again!  I will be procuring all of the running rigging in the next couple of weeks.  Ah, what a way to tie one on!!!
