[Note:  I have altered the s-words so they will not be picked up by the 
originator of the s-device if he is scanning our listserv these days.  See 
below for the reason, Derek.  Your question is a good one, and not out of 
line at all.]

Too bad we do not have archives of Paddlewise.  Derek's question is an 
honest one, which in 1997 (1998?) led to the formation of this listserv as 
an offshoot of Wavelength, owing to the incessant, overbearing promotion of 
those devices by the owner of the rights to produce it.  It is a long story ...

In brief, the drawbacks of the s-device under rough seas are twofold:

1. They are devilishly difficult to install under those conditions, to such 
a degree that they almost need to be deployed before launching.

2. In heavy, steep seas, a "flat bottomed vessel," which the s-device 
produces, is exactly what you do not want.  Reason:  the flat bottom 
follows the face of the sea, and when a steep one comes along, the whole 
arrangement can get flipped upside down, where it is actually more stable 
because the weight of the upside down paddler functions as a keel.  This is 
the reason vessels designed to traverse the open ocean have deep-vee hulls, 
and flat-bottomed skiffs should avoid steep seas..

I wish John Winters were contributing more often these days, because John 
had a link to a very compelling video clip showing why a flat-bottomed life 
raft might be better termed a death raft, because it does exactly what is 
described in 2. above, in steep, heavy seas.

BTW, the seas in which that guy was rescued were fairly gnarly, all right, 
but they are in the low end of what I would call "steep, heavy seas."  He 
had no business being out there, equipped with an s-device, a destroyer, or 
an aircraft carrier.
