    Well, if you can get an offset mainmast back to the middle of the LWL, then certainly a schooner rig is possible. The poles sound good, but I've never come across any with more than ¼" wall thickness. Even if they are only ¼", they will carry a 500 sq ft mainsail and a 250 sq ft foresail, so I reckon this is a viable scheme.

    Thank you kindly for your insight. 

    I really have my heart set on a schooner. 

    I was reading a post where the  mast was offset from center,

    if this is possible the main mast could come back about a meter

    and would be about 200mm from center. 

    I have the possibility of getting street lamp poles, made from 6063 T4

    With a 10" 250mm base tapered to approximately 150mm and 8 to 10mm

    Thickness.  There's also some broken poles ,that could be inserted to strengthen the bury.

    If more information is needed please let me know. 

    Thanks

    We aren't really given enough to go on, here, but with the boat tour video on https://svonelife.com/theboat/ to help, I'd be looking at a ketch rather than a schooner, with a mizzen mast at the forward end of the stern cabin, and a mainmast somewhere between the V berths. The mizzen sail would probably be quite small, about 20% of the total area, and would act as the first one or two reefs.

    Hello. My name is Mark Shrosbree and I have just become the proud owner of a 40ft Offshore ,that I would like to covert to a junk rigged schooner.

    I crossed the Atlantic and have sailed 9000 miles in Cielo a 32ft junk,with a sail i built using Arne's plans off this site.

    The problem is that the placement of the masts is not really adjustable without compromising the interior . The forward mast can be placed 1.2m from the bow will have to remain where the mast is now, maybe 200mm aft of this position. Can this work?  Any help with this would be greatly appreciated.

    Also,  is there a member who is knowledgeable about using street lamp poles as masts?
