Here's the big picture as promised. The sections in black are "phase I", meaning this will be made first and is the minimum I need to get this thing moving. "Phase II" is in red- these are things I will add later to make it faster. Phase II includes adding some square footage to the mainsail by making it a lateen sail, making a jib sail, and making pontoons (attached on arms to the sides, called "outriggers", like Polynesian canoes)(not shown in the diagram). These additions will double my sail area, and the outriggers will make it easier not to flip over when the wind gusts into my awesome new double-sized sails.
