<p> Today we talk with Margreet Pakkert, who was kind enough to record an interview during the <a href="https://www.cultureelerfgoed.nl/actueel/nieuws/2025/07/14/veldschool-scheepsarcheologie-flevoland-2025-van-start" rel="noopener noreferrer" target="_blank"> Flevoland 2025 Field Work Archaeology Open Day</a> . The students were supervised as they document a Dutch <a href="https://nl.wikipedia.org/wiki/Waterschip" rel="noopener noreferrer" target="_blank"> Waterschip</a> . This is a type of fishing vessel that was common in the <a href="https://en.wikipedia.org/wiki/Zuiderzee" rel="noopener noreferrer" target="_blank"> Zuiderzee</a> before it was <a href="https://en.wikipedia.org/wiki/Zuiderzee_Works" rel="noopener noreferrer" target="_blank"> reclaimed</a> to form the province of <a href="https://en.wikipedia.org/wiki/Flevoland" rel="noopener noreferrer" target="_blank"> Flevoland</a> . As fish were caught they were kept alive in two chambers in the boat that were open to the sea¸ allowing the fishermen to deliver the freshest of fish to <a href="https://asterix.fandom.com/wiki/Unhygienix" rel="noopener
noreferrer" target="_blank"> their market</a> .</p> <p> As the water table in Flevoland is lowering, the shipwreck will soon rot away. So the team are out teaching students the craft of documenting the find and preserving what is unique. The ship itself sank between 1520 and 1530.</p>

<h3>The front/Fore</h3>

<p>
There is a large event tent often used for weddings, covering the escalation area.
The legs of two people can be seen standing on the grass above two archaeologists who are in the wreck.
From the grass level, there is a 30cm/1 Foot layer of sandy soil until there wreck begins.
The body of the ship is exposed and we can see the interlocking planks that form the hull.
There is a "stepping stone" path made from sand bags from the keel/center spine of the ship, to the surface.
One archaeologist stands at the end of this path with a bucket and at his feet is a scoop that he is using to fill it.
The lower part of the ship is filling with water that is seeping in from the surrounding ground.
Another archaeologist stands in the Bow/Front of the ship with a drawing board where she is making a record of the find.
The view down the tent from front to back. The ship lies about 15
Degrees to port (left in direction of travel)
A photographer is taking pictures.

<h3>The <a href="https://nl.wikipedia.org/wiki/Bun_(schip)">bun/fish compartment</a></h3>
<p>
In the body of the ship we see three wooden partitions, that form
the two chambers that were used to keep the fish alive.
Although not visible to the untrained eye, there are holes to the
outside sea.

A close up of the 2M/6Foot wooden sleeper that lies on a forklift
pallet.
It is about 15CM/6Inches thick.
This has a about 30cm/1 Foot square hole in it, that is only about
5CM/2Inch deep.
This was used to hold the bottom of the mast.

<h3>The Back/Aft</h3>

<p>
A view from the back from the back of the ship. We can see that
there is a rip in the hull behind the last fish compartment and
the back of the ship.
Was this a collision or did it occur after sinking ?
An archaeologist is fighting a loosing battle to scoop out water.

<h3>The glamour of the dig.</h3>

<p>
The back of the site tent showing the woodland in the background, a pile of soil that was removed, and a another pile of rotting wood from the ship.
There is a makeshift pool of water used to store water pumped from the wreck.
The front of the site tent showing the woodland in the background, some storage shipping containers, some steel plates used to spread the load of heavy machinery.
A 2M/6Foot wooden sleeper lies on a forklift pallet.
A earthen mound is in front of the woods.
In front of that is a very wet and damp looking tarpaulin with parts of the ship. They are normally kept wet covered with another tarpaulin so they will not rot.
Each has a label on it.
Some are held vertical by sandbags.
There is a view of the pile of rotten wood, the eacavated soiland the pump pool.
There are some rusted iron as braces in the wood. 
There is a rust shaped axe.

<h3>Information Displays</h3>

<p>

A informational poster showing how they determined the date to be <a href="https://en.wikipedia.org/wiki/Dendroarchaeology">Dendroarchaeology</a>.
If two trees grew during the same period, the thickness of their rings during that period will be the same. 
Archaeologist were able to make a complete historical map of tree rings going back to prehistory.
They did this by comparing the overlapping tree rings from in existing buildings, shipwrecks and artwork. 
In some cases there were receipts from wood choppers for the timbers.
Further back can be used by comparing overlapping rings in different artifacts.

<p>
A informational poster tells us the shipwreck was discovered in 1972 when the land was drained.
The ship is 16 meter long and 5.5 meter wide, which is a small version as they often got to 20 meter in length.
The ship was complete to the top of the <a href="https://nl.wikipedia.org/wiki/Bun_(schip)">bun/fish compartment</a>.
It sank somewhere between 1520 and 1530.
It continues to give a timeline of the discovery.<br />
The next poster shows the 3d scans from 2022 to 2025.<br />
2022 Shows the front half of the ship with a rats nest of broken timbers.<br />
2023 The entire top deck is exposed <br />
2024 and 2025 show the wood is now cleared down to the frame of the ship.<br />
There are also 3D printed versions of the scans in cases.
