So, i have a '73 46.6 sportfish. She's a good boat but well past her prime fishing days unless she gets a refit and repower. I'm currently living aboard and that was my intent from the start. I'm wondering if anyone has converted theirs from the standard cabin, v-berth and second head design into a single stateroom and expanded head design. The idea would be to install a full shower or shower/tub and expand closet space. Are any of the interior walls load bearing. It doesn't appear so.
