In the space forward on the main-deck we have the fore-hatch, and by the side of this a room entirely lined with zinc plates, which serves for storing furs. Forward of the fur store is fitted a 15 horse-power one-cylinder Bolinder motor for working the capstan; the main features of its working will be seen in the drawing. There are two independent transmissions: by belt and by chain. The former is usually employed. The chain transmission was provided as a reserve, since it was feared that belt-driving might prove unserviceable in a cold climate. This fear, however, has hitherto been ungrounded.
Forward of the motor there is a large iron tank to supply water for cooling it. In the same space are chain-pipes to the locker below and the heel of the bowsprit. This space also serves as cable-tier.
On the upper deck we find aft, the opening of the rudder-well and that of the propeller-well, covered with gratings. A piece was added to the lower part of the rudder to give more rudder area.
Forward of the propeller-well comes the reserve steering-gear, almost in the same position formerly occupied by the only steering-gear; the ordinary steering-gear is now moved to the bridge. The old engine-room companion aft is now removed, and forward of the after-wheel is only the skylight of the after-saloon. Up through the latter comes the exhaust-pipe of the main engine. Forward of and round the mizzenmast is the bridge, which is partly formed by the roofs of the large chart-house and laboratory amidships and the two houses on each side. The chart-house occupies the place of the old boiler-room ventilator, and abuts on the fore-deck. (It is thus a little aft of the place occupied by the chart-house on Nansen's expedition.) It is strongly built of timbers standing upright, securely bolted to the deck. On both sides of this timber work there are panels, 2 inches thick on the outside and 1 inch on the inside, and the space between is filled with finely-divided cork. Floor and roof are insulated in a similar way, as is also the door; the windows are double, of thick plate-glass. Inside the chart-house, besides the usual fittings for its use as such, there is a companion-way to the engine-room, and a hatch over the manhole to the main supply tank for oil-fuel. The opening in the deck has a hatch, made like the rest of the deck (in two thicknesses, with cork insulation between); the intention is to cut off the engine-room altogether, and remove the entrance of this companion during the drift in the ice through the Polar sea. The side houses are constructed of iron, and are not panelled; they are intended for w.c. and lamp-room. On the roof of the chart-house are the main steering-gear and the engine-room telegraph. On the port side, on the forward part of the after-deck, a Downton pump is fitted, which can either be worked by hand or by a small motor, which also serves to drive the sounding-machine, and is set up on the after-deck. Forward of the starboard side house is the spare rudder, securely lashed to deck and bulwarks. On each side of the chart-house a bridge leads to the fore-deck, with ways down to the workroom and fore-saloon. On the fore-deck, a little forward of the mainmast, we find the two ship's pumps proper, constructed of wood. The suction-pipe is of wood, covered on the outside with lead, so as to ]prevent leakage through possible cracks in the wood; the valves are of leather, and the piston of wood, with a leather covering. The pump-action is the usual nickel action, that was formerly general on our ships, and is still widely used on smacks. These simple pumps have been shown by experience to work better than any others in severe cold. The fore-deck also has skylights over the fore-saloon, the main and fore hatches, and finally the capstan. This is of the ordinary horizontal type, from Pusnes Engineering Works; it is driven by the motor below, as already mentioned. The capstan can also be used as a winch, and it can be worked by hand-power.
The Fram carries six boats: one large decked boat (29 x 9 x 4 feet) -- one of the two large boats carried on Nansen's expedition -- placed between the mainmast and the foremast, over the skylight; three whale-boats (20 x 6 feet), and one large and one small pram; the two last are carried on davits as shown in the drawing. One of these whale-boats was left behind on the Ice Barrier, where it was buried in snow when the ship left. It was brought ashore that the wintering party might have a boat at their disposal after the Fram had sailed.
For warming the vessel it is intended to use only petroleum. For warming the laboratory (chart-house) there is an arrangement by which hot air from the galley is brought up through its forward wall.
The vessel was provided with iron chain plates bolted to the timbers above the ice-skin. The mizzenmast is new. There was a crack in the beam that forms the support for the mizzenmast; it was therefore strengthened with two heavy iron plates, secured by through-bolts. Two strong steel stanchions were also placed on each side of the engine, carried down to the frame-timbers. The old mizzenmast has been converted into a bowsprit and jib-boom in one piece. There are now standing gaffs on all three masts. The sail area is about 6,640 square feet.
All the cabins are insulated in the same way as before, though it has been found possible to simplify this somewhat. In general the insulation consists of:
1. In the cabins, against the ship's side and under the upper deck, there is first a layer of cork, and over that a double panelling of wood with tarred felt between.
2. Above the orlop deck aft there is a layer of cork, and above this a floor of boards covered with linoleum.
