At 21' long and 18" wide at the widest point, 15 -3/4" at the 4" water line, this is a boat for the experienced kayaker. I had Doug build mine in the Kevlar layup, overstern rudder only and it is an absolute dream on flat water. I was cruising in this boat easily at 6mph from Day 1 and I have no idea what the hull speed actually is because my skills as a paddler have me nowhere near finding it. It certainly must be above my top speed of 8.6mph for a short sprint and above my ~6.4mph in open, flat water. The boat comes with a tiller bar and I did not like the concept at first (and it took me a little while to get used to), but now I've seen the light and understand why this is a superior steering setup once you have the proper leg pumping action during rotation. The boat is a dream and leaves absolutely no wake.
The only minor complaint I have is the plastic cable guides that hold the rudder cables in place on the deck seemed to have been over-tightened and they cracked and two subsequently broke off so I've since replaced them all (which was a pain when you think about trying to get a tool on a nut that is ~7' behind the seat) but other than that minor point the boat is a dream. Very fast. More stable than an Epic V12 ski for sure, but still tippy for anyone coming from an ocean kayak. The craftmanship in this boat is superior on all measures and the boat attracts attention and invites questions wherever it goes. I can't wait to buy my next Bushnell boat.
