Wed - November 9, 2005CoastRunner - A New Kayak Design and New Virtual Race Entry Bjørn
Johansen from Denmark entered the 5 mile virtual
race in a new kayak of his design: Coastrunner,
length 5.20m (17'0.7"), beam 0.54m (21.25").
Bjørn paddled CoastRunner with the average speed of 7.03 mph over 5 miles. Earlier this year he entered the race twice with the Escape kayak reaching 6.98 mph and 7.20 mph. The lines of the CoastRunner are based on one of the most successful designs in this class, the Escape, by the same designer. CoastRunner is however designed without regard to any specific rules. The traditional length, 5.2 m, is maintained. The waterline beam is increased about 5 % in comparison to the Escape, which corresponds to an increase in metacenter height (a measure of static stability) of 15 %. The cost of this increase in stability is a loss in speed of 1-2 %, when compared to the Escape. The pronounced flare of the midship sections increases the waterline beam with displacement, and gives the boat excellent handling qualities over a large load range.
