Combi - keels:
Concept "Combi - keels" is made to satisfy the need of low center gravity of keel
in respect of lateral plan area, depth, area of wet surface and transfer of power
from keel to boat.
In relation to the above a combi-keel has the material of the lowest density in the
upper part of the keel, using for instance. cast-iron or polyester concrete.
ØRKILD delivers combi-keels, as to customer's specifications, mostly with upper part
of cast-iron, but also with upper part made of polyester concrete.
Delivery worldwide at fixed, competitive prices. |
