Write a Review
Printed plans shipped from Great Britain


This design is a development of the 18’6” Marathon open canoe with it's easily driven asymmetric hull shape. Beam has been reduced to 28" which is positioned down at the waterline. Like her smaller sister she has 5 planks per side and uses the stitch and tape method of construction for ease, low cost and lightness. Again she has tumblehome in the topsides making her easier to paddle.
