Its do-able in a fully rigged 18' bucket boat
We just ran it a couple weeks ago at around 1900 in our 18' expedition rig. We had done Ruby/Horsethief the 3 days before and met up with friends for a daily Westwater trip. They were all in 14/15 foot empty self bailers, we were in our big fat pig, complete with kitchen, big cooler, everything for a multiday trip. We did alright, Skull was sketchy, we ended up going right of Skull rock.......barely. We got surfed into a rock somewhere above Skull rapid and took a hard shot to the floor, but survived. All in all, I would have liked a smaller/lighter boat, but it is definitely do-able in a big boat.
