berth
I think what your referring to is the same on Pearson boats. The board makes the berth wider to sleep on. Not that much wider. I have a 22 and I find it is getting to be a little to small for me and my family so I am trading up to a 27 Hunter, I am very happy with the way the Hunters handle and the space and comfort they provide. I hope i was of some help. Have fun on the water.
