stepping stones of maritime history

History

Construction

Length from the stern to the bow post is more than 35 metres. Width and height are not measured yet. It is a carvel built vessel, but it is not known if the ship was built according to a frame first or shell first method.

 

Cargo

The cargo consists of Iberian jars, schist slates, casks with anchovies and grapes, little bells, balance bowls and wood to make small oval wooden boxes.

From the ship's inventory some cooking gear, ceramics and cannons remains.

History

Building: second half 17th century.

Tree ring date (dendrochronology): after 1645 AD and after 1646 AD (postquem).

Wreckage: second half 17th century (dating by mobilia).

The origin of the vessel is probably not Dutch. The wood, inventory and construction of the vessel point to a northern German origin. The largest cargo (jars) points to an Iberian origin. Grapes and small fish (anchovies) also point in that direction. It is not yet known where the schist slates come from.

Hypothesis: A German ship from the second half of the 17th century which was wrecked on its return voyage from the Iberian Peninsula. It was lying on the Texel roads probably because it intended to trade goods with the Amsterdam Staple Market.

Description

Armed trader with a squared stern and two continuous decks with a considerable flair. The exact type of the ship is not known. The wreck site is 40 by 25 meters. What makes the ship approx 40 m long.

The intensive use of pinewood (Pinus Sylvestris) in the construction indicates that it was not a Dutch vessel.

Date

Because of the amount of pinewood and the lack of well-preserved and accessible oak, dendrochronological dating was executed on pinewood samples from the deck beams. Two samples gave post quem dates of "after 1645" and "after 1646".

The wood originates from northern Germany.

Armed merchant ship.

Status

The wreck is protected with polypropylene nets. The BZN 10 has been investigated and monitored in several projects and methods have been tested for managing and protecting - and for non intrusive research.

Projects
Moss EU project
MACHU project
SASMAP project
Research 2013

From 10-21 june 2013 the Maritime Programma of the RCE conducted research on the BZN 10. Mats of artificial seagrass were placed at the wreck. This new dynamic protection method could possibly be a good addition to the more static polypropylene nets filled with sand.

Research 2014

In 2014 new mats of artificial seagrass were placed at the BZN wreck.
