Honeycomb or foam sandwich hulls have now become the norm for rowing boats, and the method of construction used at most boat builders is surprisingly similar. 　A selection of carbon, kevlar and fibre glass cloths are bonded to a core material, usually honeycomb or core mat, then cured under vacuum at high temperatures. This is the standard method used by the majority of boat builders, but it is extremely labour intensive. While China has the suitable technological know-how, labour costs are still very low in terms of foreign currency. For this simple reason, China is rising to the top in the boat building industry.

The reason for using a core material to make a sandwich structure is to increase thickness. As hull thickness increases there is a dramatic improvement in boat stiffness. As honeycomb is so light it is an ideal core material. Core mat can also be used as a core, but because of its greater density, it results in a heavier boat. However, core mat is better at taking bumps, and will be easier to repair than honeycomb.

In total we now offer 4 different construction types for rowing boats.  They all use sandwich construction.  With the low cost of Chinese boats we decided there was little point in offering a single skin alternative.
