As we prep the interior for first overnight trips in probably March I am trying to think ahead about sleeping configuration. The vintage HR28 has 2 v-berth and 2 quarter berth sleeping place. Each have 4" of decent foam at this point. We feel sleeping in v-berth would leave CA in open to Co figure for hanging out. But we have never slept on a boat. Where do most folks sleep with choices like ours and why? Will the 4" of foam work? I am 6'1" 225 wife is petite so will fit anywhere. Looking for opinions. Also if in the v-berth are there any options for custom mattresses that would not be at up the budget too bad?
