No jibs, easier to shunt, rear rudder heavily loaded, use front rudder for steering?

On sailing the 40 foot trimaran Aotea:
"These boats are flat out exhilarating. Aotea was easy to singlehand, and we hit upwind speeds as high as 18 knots and close to 30 off the wind. Can you imagine how much fun a one-design fleet would be in San Francisco Bay?" (full interview - SailingAnarchy.com)
