Locker mods on H25
Having extensively rebuilt the interior of my '74 H25, I added 'duffel-bag lockers' over the footwells of the quarter berth and the starboard berth (opening in the head), smaller 'stuff lockers' along the side of the quarter berth, and a hanging locker in the v-berth (making it only a single bunk now). The 'wet locker' is the side of the companionway locker where there are hooks for wet things and drains into the bilge. (The trash bag hangs there as well.) Aside from the original spaces under the galley and q-berth, each bunk has a 60-inch nylon gear hammock for sweatshirts, blankets, etc. Stuffed full the hammock is a decent backrest.
I also added many small lockers all over the boat-- above the q-berth, in the head, under the galley, under the ladder, other side of the v-berth, etc.
Do not overlook the footwells of the settee berths which is where most people keep the bedding. It's dry and out of the way till you need it to sleep.
