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.
