… and then the cross rib #1.
Now install both small cross ribs: one at the bow
(narrower) and the other one at the stern (wider)
At the bow as at the stern, place the cross rib
tilted onto the clip on the keel rod, then right it up
and push the ends into the intented holders on
each side of the hull.
Push from the outside of the hull to help the ends
of the cross rib fit into the holders.
bow cross rib = narrow
stern cross rib = wide
