The keel was preserved along an extension of 6.05 m on the upper portion of the shipwreck, and at least 1 m on its lower portion.

Its cross-section was observed both at the fracture section and between floor timbers C10 and C11.  In both places it presented a "T" shaped section with a trapezoidal rectangular body (Fig. 1).

Towards the post the keel presented a slightly smaller sided dimension, around 15.5 cm.  This may signify that the keel section varies along its length, and that the protruding notches disappear as the angle of entry of the garboards gets steeper.
