In anticipation of the rush to get round the mast, the front foot is placed by the mast foot.

Ljungström also developed a solution to easily adjust the mast tilt (forward / backward) through a roll in the mast foot (april 1921).

The mast foot casting forms a ball which steps into cup-shaped shoe riveted onto the forward crossmember and there is a Teflon disk separating the two.

Note how much more upright his rig is compared to B's, and also that by being further underneath the boom, it is easier to apply pressure to the mast foot.

On the mast itself no undisturbed measurements can be made below 20 m. Auxiliary 20 m masts are installed to the SE and the NW at sufficient distance from the mast foot building.

When lowered the mast foot was kept in the base of the mast step and the top of the mast secured in a natural wooden crook about 1.5 m-2.5 m high, on the port side, so that it did not interfere with steering on the starboard side.
