Once the Bulkheads and bridge deck are on it’s time to build the anchor lockers and floor of your hulls, this gives you plenty of time to think about what you want the layout of your boat to look like.
For me with 3 kids I wanted 2 single berths and 2 queen berths up the front with a toilet shower washing area at the back of one hull and initially I was going to have a double berth in the rear of the other hull, thinking that this would give me space for the 3kids and the extra queen berth could be for the grandies if and when they came with us. I went with 2 deviations from the plans here having a curved anchor locker deck and 2 little storage compartments with shelves for the front single berths.
