Colin Archer then built the ship —­ Fram was her name —­ and she showed —­ first on Fridtjof Nansen’s famous voyage, and afterwards on Sverdrup’s long wintering expedition in Ellesmere Land, that she answered her purpose completely, nay, she greatly exceeded the boldest expectations.

Then Roald Amundsen decided to set out on a voyage not less adventurous than the two former, and he looked about for a suitable ship.  It was natural that he should think of the Fram, but she was old —­ about sixteen years —­ and had been exposed to many a hard buffet; it was said that she was a good deal damaged by decay.

Roald Amundsen, however, did not allow himself to be discouraged by these misgivings, but wished to see for himself what kind of a craft the Fram was after her two commissions.  He therefore came down to Horten with Colin Archer on June 1, 1908, and made a thorough examination of the vessel.  He then, in the spring of 1909, requested the Naval Dockyard at Horten to repair the ship and carry out the alterations he considered necessary for his enterprise.

Before giving an account of the repairs and alterations to the vessel in 1909 —­ 1910, we shall briefly recapitulate, with the author’s permission, a part of the description of the Fram in Fridtjof Nansen’s work, especially as regards the constructive peculiarities of the vessel.

The problem which it was sought to solve in the construction of the Fram was that of providing a ship which could survive the crushing embrace of the Arctic drift-ice.  To fit her for this was the object before which all other considerations had to give way.

But apart from the question of mere strength of construction, there were problems of design and model which, it was thought, would play an important part in the attainment of the chief object.  It is sometimes prudent in an encounter to avoid the full force of a blow instead of resisting it, even if it could be met without damage; and there was reason to think that by a judicious choice of model something might be done to break the force of the ice-pressure, and thus lessen its danger.  Examples of this had been seen in small Norwegian vessels that had been caught in the ice near Spitzbergen and Novaya Zemlya.  It often happens that they are lifted right out of the water by the pressure of the ice without sustaining serious damage; and these vessels are not particularly strong, but have, like most small sailing-ships, a considerable dead rising and sloping sides.  The ice encounters these sloping sides and presses in under the bilge on both sides, until the ice-edges meet under the keel, and the ship is raised up into the bed that is formed by the ice itself.

In order to turn this principle to account, it was decided to depart entirely from the usual flat-bottomed frame-section, and to adopt a form that would offer no vulnerable point on the ship’s side, but would cause the increasing horizontal pressure of the ice to effect a raising of the ship, as described above.  In the construction of the Fram it was sought to solve this problem by avoiding plane or concave surfaces, thus giving the vessel as far as possible round and full lines.  Besides increasing the power of resistance to external pressure, this form has the advantage of making it easy for the ice to glide along the bottom in any direction.
