Test-sailings at Als
From the 31st
of august until the 3rd of September we performed a series
of test in co-operation with The Center for Maritime Archaeology in
Roskilde. Thursday and Friday 4 members of Nybro-Furåens and Esrums
canoe- and kayak-clubs participated together with members of the
guild. Saturday and Sunday a team from the Dragon-boat-club Viking
Team Copenhagen (http://hjem.get2net.dk/vikingteam)
practiced paddling-technique in Dyvig and Mjelsvig (see
map). In the afternoon
we performed a series of towing-experiments, where the pulling-force
and the speed was measured. Friday morning we went to Stegsvig,
returned to the Stegsgaf-isthmus where we went ashore and had our
lunch. During the afternoon we placed two buoys as marks for the
speed-experiments Saturday and Sunday. During the day we performed
more speed- and maneuvering-experiments.
and Sunday were set aside for experiments with professional paddlers.
They performed a series of speed-experiments. Over a length of 250
meters the speed was 8.2 knots. The cadence was 65 strokes per minute.
Over a length of 1000 meters the speed was 7.9 knots. A drummer placed
in the front of the boat controlled the rhythm of the paddling.
had planned to go for a long trip from Dyvig to Stevningnor (about 8
nautical miles) and return to Dyvig Sunday. But we had to drop this
trip due to weather forecasts promising strong winds Sunday.
forecasted Sunday started with strong winds from the north and we
decided to try out the boat in hard weather in Stegsvig and Als Fjord.
The dragon-boat-team paddled passed Lønsømade to Als Fjord and went
north against the 1 meter high waves. Tilia handled the waves very
well without taking in water over the gunwale, but when she was riding
on top of the waves the water trickled through the bottom sewing.
Tilia didn’t even have problems when she was turning across the
gave us some experiences with the paddles. The paddles for the two
frames in front and the two in the rear must be longer in order to
reach the water properly. The blade of the paddles must be sharpened
in order to be easier to drag out of the water. The attachment of the
steering-oar to the keel horn gives a lot of whirls so we consider
moving the steering oar further backwards.
