Aside from "Risk Homeostasis Theory", there is another interesting moment in "Statistics" section. Injuries and fatalities rate in kayak/canoe group is about 6 times less than in open motorboats (cabin motorboats is the second risky group). Day-sailing dingies have nearly zero rate of injuries and fatalities. Regarding reported 20% of drag induced by sponsons: probably so, speaking of sponsons attached along the hull. Outrigger sponsons slow me down by at least 30% (feels like 50% to me), due to poor maneurability and higher wind resistance caused by outrigger arms, mast and furled sail on the deck (this is what outrigger is needed for, actually). Absolutely agree that crossing tidal current (and/or headwind) with sponsons may reduce performance way too much. It is hardly realistic on water to dismount outrigger sponons like BSD or Folbot, or simply sponsons attached to the hull - no time, and conditions don't help either. ----- Original Message ----- From: "Nick Schade" <nick_at_guillemot-kayaks.com> To: "'Paddlewise'" <PaddleWise_at_paddlewise.net> Sent: July 22, 2004 5:38 AM Subject: [Paddlewise] Efficacy of Sponsons on Canoes and Kayaks > A report just out from the Coast Guard: > http://www.uscgboating.org/safety/efficacy.htm > > Nick Schade *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
