The Nautical World of Tetavon

In the land of Tetavon, with a technology of the mid-Middle ages, nautical science remains at the level of the rowed galley and the early sailing ships that typically do not venture very far from land. This limits the nautical equipment to Knarrs and Cogas.

The Knarr

A Knarr is a type of Norse merchant ship famously used by the Earthly Vikings. Knarr (knorr or knörr plural) is of the same clinker-built method used to construct longships, karves, and faerings.

The name Knarr is the Old Norse term for ships that were built for Atlantic voyages. The Knarr was a cargo ship, the hull was wider, deeper and shorter than a longship, and could take more cargo and be operated by smaller crews. They were built with a length of about 54 feet (16m), a beam of 15 feet (4.5m), and a hull capable of carrying up to 24 tons.1 It was primarily used to transport trading goods like walrus ivory, wool, timber, wheat, furs and pelts, armour, slaves, honey, and weapons. It was also used to supply food, drink, and weapons and armour to warriors and traders along their journeys. Knarrer routinely carried livestock and stores.

The only knarr found to be well preserved was in a shallow channel in Roskilde Fjord in Denmark of 1962 along with two warships, a Baltic trader, and a ferryboat. Archaeologists believe that the ships were placed there to block the channel against enemy raiders. Today, all five ships, known as the Skuldelev ships, are being restored at the Viking Ship Museum in Roskilde.

The knarr might have been in use in colonizing , although the similar small cargo vessel the byrthing (berthing) is another major possibility. It was possibly the same kind of sailing vessel that the first colonists used to sail to Tetavon.

The Cog

A Cog (or cog-built vessels) is a type of ship that first appeared in the early centuries, and was widely used. Cogs were generally built of oak. This vessel was fitted with a single mast and a square-rigged single sail. These vessels were mostly associated with seagoing trade.

Cogs were characterized by a flush-laid flat bottom at midships but gradually shifted to overlapped strakes near the posts. They had full lapstrake planking covering the sides, generally starting from the bilge strakes, and double-clenched iron nails for plank fastenings. The keel, or keel-plank, was only slightly thicker than the adjacent garboards and had no rabbet. Both stem and stern posts were straight and rather long, and connected to the keel-plank through intermediate pieces called hooks. The lower plank hoods terminated in rabbets in the hooks and posts, but upper hoods were nailed to the exterior faces of the posts. Caulking was generally tarred moss that was inserted into curved grooves, covered with wooden laths, and secured by metal staples called sintels. Finally, the cog-built structure could not be completed without a stern-mounted hanging central rudder, which was a unique northern development.1 Cogs used to have open hulls and could be rowed short distances. Later in their use, they received decks.
