I got spanked really bad
a few weeks back by a smaller boat. There were several factors involved such as his boat had nearly the same sail area as my SC, but I out weighed him by 300 pounds, plus I had at least another 300 # in crew weight that he did not have. The biggest factor though were and are my novice sailing abilities.
It was only blowing 10 to 15 but all you could see from him was sea spray as his windward hull would kiss the water.
As far as the boat, everything furls. The main, the jib, and the Jennaker if you have one. I don't know about a second slug on the halyard...I don't have one on mine. The main sail has a few additional cringles in which one can depower the sail by reefing as described by another poster and inserting the downhaul into the cringles to pull the slack out.
Matt is on target about the room. Six people can be aboard and not be sitting in each others laps. It's a great boat really, for what it is.
