A 15th - one C shipwreck off the seashore of Sweden may be Scandinavia ’s oldest shipwreck built in the innovative " carvel " style — a design that consecrate it the strong suit to carry heavy carom , archaeologists say .
The wreck at Landfjärden , to the south of Stockholm , is one of five in the area that have been know since the 1800s . They were commonly thought to have been from ships dating to theViking Age(A.D. 793 to 1066 ) .
The wreck is one of five located in waters near the seaside village of Landfjärden about 20 miles south of Stockholm.
But last twelvemonth , nautical archaeologist atVrak , the museum of wreck in Stockholm , revealed that four of the crash day of the month to the 1600s and 1700s and that the sometime wreck was build before 1480 and perhaps as ahead of time as the 1460s , museum conservator and project managerHåkan Altrocksaid in astatement .
" It ’s a large ship , likely about 35 metres [ 115 feet ] tenacious and 10 metres [ 33 feet ] wide , " he said . " The ship ’s frame still rises high up above the seabed , and in the stern , both the sternpost and rudder remain just . "

New shipbuilding technique
The most significant aspect of the wreck , now known as " Vrak 5 , " is that it was built in the " carvel " style , with planks on the Cordell Hull that were moneyed with neighboring planks so that the whole Kingston-upon Hull surface was relatively unruffled , Altrock said .
By direct contrast , traditional Nordic ship , such asViking longships , were built in the " cinder " style with overlap plank , which had made them light and comparatively flexile .
But the use of carvel - style flush planks — an innovation from the Mediterranean date to about the 7th hundred A.D. — think of that a ship ’s hull could be reinforced with frame to make it stronger . This was an crucial consideration when ship started carrying cannon in the 15th century , Altrock said , so traditional " clinker - built " ships soon became obsolete .

A new depth psychology show that " Vrak 5 " is the earliest of the wrecks and was build in the 15th century .
geographic expedition show the ship ’s Isaac Hull was made with flush carvel - style planks , instead of the overlap clinker - style plank used in traditional Nordic shipbuilding .
Important wreck
These details make Vrak 5 Florida key to understanding the transition from clinker - built to carvel - built ships — an important period in Sweden ’s maritime history , Altrock said .
" We contrive to utilize for external financial backing for an excavation , " he said . " This ship represents a riveting link between medieval and New shipbuilding . "

The new depth psychology also show that the trees used for the wood in Vrak 5 had been felled in Sweden ’s southern Kalmar region or in the nearby Blekinge neighborhood , Altrock enjoin .
The Vrak archaeologist have also made a digital model of the crash using photogrammetry — a technique that combines digital picture so that their positions are ponder in three dimensions — and the results arenow online .
