| Center hull rarely touches the water, but adds an additional counterbalance to the enormous rigid rig. |
 |
| Sloop rigged with a fabric jib, the high aspect ratio Main Sail is similar to my Hobie 20, except for the fact that it is 6.7 times larger and solid instead of fabric. The proportions however, are similar. One difference is that their Jib is fuller closer to the water and is a true Genoa in the sense that it's sail area looks to approach that of the main. |
 |
| Note the wrinkles on the leading edge of the Genoa. Could the jib halyard tension be insufficient? |
 |
| Roughly 15 degree desired angle of heel with the mid hull 8 feet off the water. |
 |
| Some manner of main sail trimming louvers controlled by the mid-hull crew. |
 |
| Curved Dagger boards to accommodate effective angle of attack due to heel. I don't quite understand why they are curved towards the heeling direction instead of away. Do they act as a hydrofoil? |
The blog below has a bunch of amazing photos of the construction of this beast. Apparently the mainsail construction took place in San Diego. With the large solid wing mainsail approaching 200 feet off the water, everything about this boat seems to have been all-out, spare no expense engineering.
