I do a modified version of what Jake mentioned. While hanging on to the crossbeam, I find the dagger board with my foot and get my leg to the outside of it and duck under the boat. The board ends up between my legs. My opposite leg now is wrapped around it with my knee bent as I pop up on the other side. I reach up with one hand, find the shroud, then find a trap handle. Then I throw one leg on the hull and pull myself with the trap handle up on the boat. When you have a full camelback and a pfd with a radio and other safety gear, it can be a bit more added weight that you realize that you have to pull up but this worked many times for my 280 pound butt (which is 53 pounds lighter now).
