Svensk sammanfattning
På uppdrag av Munkebogatans Samfällighetsförening och Länsstyrelsen
i Västra Götalands län utförde Bohusläns museum i juni 2010 en marinarkeologisk förundersökning av fornlämningen Tossene 983, belägen inom vattenområdet Strandhamns kile, Ulebergshamn, Sotenäs
kommun. Förundersökningen föranleddes av föreningens planer på att
anlägga en brygga i området. Tossene 983 utgörs av en fartygslämning
vilken av traditionen utpekas som ett av den holländske köpmannen
och redaren David Slamans fartyg. Förundersökningen resulterade i
positionsbestämning och preliminär avgräsning av skeppskonstruktionen. En dendrokronologisk analys antyder att fartyget kan härröra från
mitten av 1500-talet, vilket gör den påstådda kopplingen till Slaman
osäker. Vid provgropsgrävningen framkom dessutom ett hamnkulturlager (Tossene 1013) vilket utifrån fyndmaterialet grovt kan dateras till
perioden 1600-1900-tal. Den planerade bryggan kommer inte i direkt
konflikt med fartygslämningen, men för att förhindra propellermuddringseffekter anser Bohusläns museum att de tre yttersta båtplatserna på
bryggans södra sida bör utgå. Dessutom föreslås permanent utmärkning
med bojar samt informationsskyltar på land. Vad gäller kulturlagret så
bedöms inte detta ha sådan dignitet och omfattning att det inverkar på
placeringen och utformningen av bryggan.
Background
In June of 2010 Bohusläns museum, in cooperation with Vänermuseet,
carried out a preliminary underwater archaeological investigation (förundersökning) in Strandhamnskile, Ulebergshamn, Tossene socken,
Sotenäs kommun (figures 1–5). The investigation was undertaken by
request of the client Munkebogatans Samfällighetsförening and Länsstyrelsen of Västra Götalands län following an application for permission to construct a jetty at the site. Based on the known ancient site in
the area, the shipwreck Tossene 983 which is also known as “Slaman II”,
it was decided that an archaeological investigation would be required.
The purpose of the preliminary investigation was to determine the presence and extent of submerged archaeological remains in the area and
to limit potential damage to sites by the development.
Tossene 983 is associated with a local tradition that a Dutch merchant
who lived in the area in the 1600s was said to have scuttled some of his
ships in the harbour. This tradition was one of the motivations for surveys conducted by the Göteborgs Amatördykarklubb between 1949 and
1966. Other registered monuments in the vicinity include Tossene 976
and 979 which consist of ballast mounds. Tossene 976 is located at the
entrance to Strandhamns kile and Tossene 979 is located in the centre
of Strandhamns kile.

Landscape
Natural and cultural landscape
Ulebergshamn is situated to the south east of Strandhamns kile, a sheltered natural haven with its entrance to the south west and runs to land
between the Vindeklätten and Krasseberget hills. It is sheltered to the
north by the Tvillingeberget and Pigeberget hills and has a maximum
water depth of 3–4 meters. Further out to the west is the Ösöfjorden,
leading into the Soten and Skagerrak.
Ulebergshamn is first mentioned as a port in the year 1594. It is unclear when settlements were first established at the site, but it is likely that
permanent residents were there toward the late 1500s. It has been stated
that Ulebergshamn functioned as a shipping port for timber. According
to local tradition, a merchant and shipowner named David Slaman, who
lived and worked in Ulebergshamn during the 1600s, scuttled five of his
ships in the harbour. The scuttling is alleged to have occurred shortly
after the Peace of Roskilde in 1658, after which the Swedish crown, for
some reason, demanded control of his vessels.

Ancient monument environment and
previous investigations
A number of surveys were conducted between the 1940s and 1960s in
reaction to this local tradition by the Göteborgs Amatördykarklubb. The
seasonal investigations were in cooperation with the Sjöfartsmuseet in
Göteborg. Two wrecks were located, which were assumed to be remains
of the Slaman vessels. The first discovered wreck, called “Slaman I”, was
located on the east side of Knivsholmen, by Knivholmsbogen, while
“Slaman II” was located inside Ulebergshamn, in shallow water along
the southern shoreline and close to the investigation area.
A smaller study in 1966 on “Slaman II” resulted in a master plan of
the site and the recovery of some finds (Bergstrand 2006a, Notini 1967).
The remains of “Slaman II” at the sediment level measured 15,5 meters
in length, 5,45 meters in width and lie in NE–SW orientation. During
the study the wreck site was dredged and the deck planking removed.
It was noted that the ship´s bottom was missing (Johansson 1992:11).
This activity was evident during this investigation as deck planking was
discovered outside the wreck, on the northwestern extent.
Among the finds recovered during the 1966 survey include a
Bartmann jug dated to the late 1500s or the early 1600s and an engraved slate with the depiction of a ship (appendix 3). The image is of a
three–masted vessel with a quarterdeck and what could be interpreted as
gun ports or guns, possibly contemporary with the jug. The large timber
dimensions along with the Bartmann–jug led the Göteborgs Amatördykarklubb to the conclusion that the wreck was either a merchantman or
a man–of–war from the late 1500s or early 1600s (Lundell 1950). The
two articles in which the diving club reported their studies (Lundell
1950, Notini 1967) mention no further discovery.
Two separate archaeological investigations in Ulebergshamn during
2006 revealed two sites of similar composition. Tossene 976 was first
detected during a sonar survey and subsequently identified on an archaeological diving survey as a ballast mound (Bergstrand 2006a).
Tossene 979 was located during an investigation within Strandhamns
kile and also consists of a ballast mound of gravel and flint. Flint as ballast for ships has been found associated with ship remains from the 1500s
and modern times in western Sweden (Bergstrand 2006b).
Method
The water in Ulebergshamn measures 3–4 meters and the bottom is of
soft sediment. Diving archaeologists performed a visual survey while
probing the bottom for evidence of archaeological remains. Dredging
consisted of a total of nine test trenches, seven within the survey area
and two along the extent of the survey area, in close proximity to the

shipwreck site Tossene 983 (figure 6). The dredged remains of each test
trench were sieved for evidence of cultural layers and archaeological remains. The extent of Tossesene 983 was determined by probing and
three timber samples from the wreck were taken for dendrochronological analysis. Analysis was performed by dendrochronologist Thomas
Bartholin (appendix 1). All diving was carried out with tethered surfacesupplied diving and diver-surface communications in accordance with
the Work Environment Authority´s (Arbetsmiljöverkets) regulations of
commercial diving (AFS 1993:57) and the diving standards of Bohuslän museum. Archaeological remains, trenches and sampling locations
were positioned by means of DGPS.
Results
Tossene 983
The location and preliminary extent of the Tossene 983 site could be
established by the visual and probing survey. The wreck, which lies in
a northeast–southwest direction, is located to the west of the proposed
jetty site and to the east of a jetty currently in use (figure 6). The extent
of the wreck was measured at 15 meters long and 6 meters wide and is
level with the marina bottom.

Dendrochronological analysis
Dendrochronological and wood provenance analysis was performed
on three samples taken from the wreck (appendix 1). The three samples were taken from a radially split deck plank, a semi-tangential strake and a tangential deck plank (figure 7). All samples were of oak and
while they lacked any sapwood, a felling date after 1517 was given. All
samples shared the same provenance of northern Germany with the best
correlation from Lower Saxony. The analysis indicates that the ship was
built some time in the mid to late 1500s. It is thus possible that the
wreck represents another and slightly older vessel than those of Slaman.
Tossene 1013
The dredging of test trenches revealed evidence of cultural layers, Tossene
1013, within the survey area and adjacent to the shipwreck site (figure
6). The items recovered from the trenches include wooden chips, animal
bones and teeth (figure 8), tile and brick fragments, fragments of flint
(figure 9), ceramic shards (figure 10), hazelnut shells (figure 11) and
leather fragments (appendix 2). The cultural layers are likely to date to
the 17th to the beginning of the 20th century. They most likely derive
from land and from ships anchoring in the harbour.

Discussion
The dendrochronological analysis performed on the three samples from
Tossene 983 revealed that the site is possibly an earlier wreck than was
previously thought, thus making the link to the Slaman tradition uncertain. Even though the wreck may not confirm the local tradition of
Slaman, it is to be considered an important find for the area. The presence of cultural layers in the vicinity of the site is also very interesting
and offers, together with the vessel remains, some insight to the use of
Ulebergshamn and its settlement during the early modern period.
Conclusion and recommendations

According to the preliminary investigation, the proposed jetty will not
directly affect the wreck site Tossene 983. Due to the shallow water on
the location, the site is at risk of being damaged by propeller wash of
boats currently using the harbour. It is likely that further boat traffic
resulting from the new jetty will increase this risk. In order to prevent
this, Bohusläns museum suggests that the three outermost moorings on

the southern side of the jetty are withdrawn. Protective measures, in the
form of marker/warning buoys placed around the site extent to limit the
amount of traffic passing over it, should also be considered.
It is also recommended that information pertaining to the wreck, its
history and significance be displayed near its location on shore to create
an awareness of the area’s cultural environment. In regards to the cultural layers revealed within the area, Bohusläns museum considers them
to be of less dignity. Thus, their presence will not affect the proposal.

Alle pröver passer fint sammen og har antagelig vokset i samme bestand. Träerne kan have vokset i
Nordtyskland, bedst er ligheden mod Niedersachsen. Det tidligste fäldningstidspunkt er 1497 plus
manglende splint på ca 20 år: 1517, hertil skal lägges et ukendt antal kernevedsårringe.
Et större antal pröver vil kunne bidrage til at präcisere skibenes bygningsår og tömmerets herkomst.
Pröverne opbevares på Nationalmuseet i Köbenhavn.
