Mike McCrea has had a unique interest in converting and outfitting tandem kayak hulls into decked solo canoes for paddling and sailing. As far as I can recall, we have never otherwise had threads about kayaks here. And won't. An occasional reference to or picture of a kayak may, however, occasionally fit into a discussion.
Because of the dearth of commercial decked whitewater C1 hulls, some whitewater canoeists have converted commercial kayak hulls for use as single blade C1 canoes by removing the kayak seats and installing foam kneeling pedestals and thigh straps. We've never had threads here showing that, as I can recall.
I have often said here, as the USCA does for racing, that the the more relevant distinction is not between canoes and kayaks as hull shapes, but between "canoeing
" and "kayaking
"—the former connoting single blade paddling and the latter double blade paddling. But that can't be a site rule here because that distinction is highly debatable for recreational paddlers, as opposed to racers, and a not insignificant number of open canoes are paddled with double blades, some or all of the time, including almost all so-called pack canoes. See this poll:
I know this can vary by weather and other factors, but pick the number that is closest to the percentage of time you use a double blade paddle on an average trip when paddling solo.
So, in summary, while this site has always been dedicated to canoes and will remain so under my administration, there are inevitable and acceptable historical and practical exceptions for decked canoes and double blade paddles.
