We were in Winter Hbr, ME when a Saber 34 came in - it was like a French circus act. People kept appearing out of the boat - didn't get a good count, but it was at least 8, could have been 10 or 12. They must have hung the small ones up in bags like salamis! They proceeded to comandeer and trash the showers. Fortunately they were gone the next day, and I didn't notice anything missing from my boat.
As for 6/4/2, I'd be tempted to push the 6 a bit - seating on the cabin top - perhaps 14?. 4 for dinner is plenty (that's all the plates we have). I'd go for sleeps 3 - we like to take a teenager for the heavy work, like finishing the leftovers and going up the mast.
