The three key words in designing and building the interior are function, weight, and cost. In order to reach my goal of a sailing displacement of 18,888# with 8888# of ballast in a near 44′ LOA sailboat, without going to any kind of exotic construction materials and methods, I am going to have to make the inside of the boat cost effective. I plan to use canvas doors in the forward cabin, fastened in place with turn buttons. This will allow plenty of ventilation with low cost and light weight.While I plan to use solid trim in the main cabin, all the vertical surfaces will be white. I like the way it lightens up the inside of the boat. One complaint I have about my Tartan is that it is very dark below, and the lights aren’t much help. It may look beautiful, but I have no desire to live in the inside of a tree.

I have always been fond of the clean traditional look of the old Northeast boats, with their white interiors with varnished mahogany trim, so I plan to finish my boat out the same way. Hopefully I can find some Honduras mahogany for all the trim-I think it is a beautiful wood and much more interesting than teak.

You can see how spacious the cockpit is in relation to the rest of the boat. The forward cabin is also quite large, for such a light narrow boat. My current boat has an inner spring mattress-very very comfortable, and I plan to have one on this boat also.

 The holding tank is in the watertight smell tight engine room, and as close to the head as possible to reduce the length of the waste line. The table folds in half and stows against the galley counter at the same height. The table leaf stows behind the settee and doubles as a cockpit table.

The door between the main cabin and the forward cabin is designed to be a watertight hatch. Since the main bulkhead has to be so strong to handle the mast loads I was going to have a composite bulkhead made and then just cut the door out of it. Then I am going to have a strong gasketed door jamb made that can be cinched tight by the grab handles on the aft side of the bulkhead. These handles will look like teak hand holds, but they will rotate 90 degrees to port to squeeze the door against the gasket.The handholds will be hidden behind the mast. There is a 4″ sill to step over, but I don’t see this as a problem, and it will also strengthen the bulkhead.

My Tartan 37 has a fold up table, and I find that I like to have it folded up 95% of the time, as it makes the boat feel much more open and it is a lot easier to move around. In the two years I have had my boat I have only had the table down twice, both times at the Bob Perry Rendezvous for Perry designs. Even when I just go down to the dock to sleep on the boat I don’t put the table down. So the table in LUCKY GIRL folds up against the aft galley bulkhead. The top of the folded table is level with the bottom of the counter back splash, about 38″ high.

LUCKY GIRL Main Cabin and Galley Arrangement

The main cabin is 15’8″ long from the aft companion bulkhead to the forward galley bulkhead. I think it will look and feel quite spacious.

Here is a close up of the head arrangement. The head doubles as a wet hanging locker and is large enough to seat down and take off your foul weather gear. There is a huge wet hanging locker outboard of the toilet. There is a fold down seat to cover the toilet when you take a shower. I had told Bob I would much rather have one big head than two small ones, and who needs two heads [with the weight,  cost and complexity] on a daysailor?

The forward cabin is quite large, with a 6″ thick inner spring mattress, a 24″ wide hanging locker on the starboard side, and a high boy type storage locker on the port side.

This is Sta. 7, which is the main bulkhead aft of the mast.


This bulkhead  will break the boat into four watertight compartments-the bow locker,  only accessible from the deck to keep the anchor rode smells from the forward cabin, the forward cabin, the main cabin, and the engine compartment. There will be no thru hulls in the main cabin. The grey water from the galley sink, head shower, and head sink will drain to a grey water tank under the port settee, and then pumped to an thru hull in the engine room.

We have designed in storage for for 6 100 amp OSM batteries to fit under the settees, three batteries on each side and as low down and close to the center line and center of gravity as possible. Three are under the aft end of the port settee, and three are under the wing of the starboard settee. They are as close to the center of gravity as possible so as to not disrupt the optimal balance of the hull and keel. They weigh 67# each. The main fuel and water tanks are also in the optimal fore and aft location and as low as possible. The tanks are approximately 75 gallons each.

This is a drawing of the engine compartment. Notice the side of the cockpit are sloped out at the top. This is to provide room for the engine hatches and to make the seats 22″ wide. This also makes it easier to brace your feet on the other side when you are heeled over. There is another water tank under the quarter berth, at the stern to act as a trimming tank if needed to balance out the port/starboard trim. I might need it to balance out the head and holding tank on the port side. I hate having a boat [like my current Tartan 37] with a list to one side or the other. Besides, that area is just about useless for anything else and hard to access to boot.
