I noticed the skipper handing the crew a line after he hiked out when going upwind, was that the mainsheet, or something else?
Also, I noticed that the skipper would hike out while the crew hoisted the spinnaker. I thought the skipper was supposed to hoist the spinnaker. Is your technique standard practice in the class?
Crew raising the kite is standard practice in crewed spinnaker rigged catamarans...period. Unless you've knocked your crew out with a dogbone, so I guess their are exceptions.
