Wharram with two masts on each hull, schooner configuration

We are speaking here of un-stayed masts buried in the hulls, carrying junk sails of moderate size. 4 sails of 15 m2 make 60 m2, while it needs 30 m2 sails on two masts, or the same on one mast. High aspect ratio, that means a square sail of 6 x 2.75m with 8 battens and 4 sheets, built very light. Reefing for heavy weather by binding 2 battens together, so stiffening the sail (reefing from the top).

Well, I have done and tested it. Broke 4 test masts in the process (glass/epoxy).
