What is the difference between the M, L, XL, and XXL ICF boats?
Our K-1 M, L and XL designs all use the same deck, but different hulls. The XXL has a different deck and larger cockpit (to fit larger people). While the overall width is nearly identical (and is identical on the M, L, and XL versions) the waterline width is different. The following items have been optimized independently on each model by Dr. Ted Van Dusen: • Waterline width • Draft or depth in water at design displacement • Prismatic coefficient (volume distribution) • Rocker profile Rather than simply scaling the various models as some other manufacturers do, Van Dusen optimized all four of the above variables in calculating the lowest drag for each displacement. He has the benefit of all test results from extensive tank drag testing that was done for the U.S. team.
