QUICK and CLEAN

A tale of two kayaks

by Laurie McGowan, with Alan Skinner

QUICK and CLEAN

 

QUICK is a racing boat; CLEAN is meant for recreational paddling. According to the theory, they should vastly exceed the potential speed of conventional kayaks. Proof of concept awaits construction and sea trials.

An accepted theoretical hull speed of a typical K1 racing kayak is 5.5 knots, yet the world record of the type has averaged 11.65 knots for 33.38 seconds over 200m.

Alan Skinner’s theory suggests that a vessel, if properly submerged aft, will generate a speed-giving wave significantly longer than its LWL (it will “plane”). In the case of QUICK, this so-called DWL (“design waterline length”; not to be confused with a conventional datum waterline, which is also called DWL) is 1.6 x LWL.
