There was a recent post about PFD's.. and this came to mind.
When, not if, you do end up in the water what would you do. This self rescue, method of re-entering your kayak has been around for a long time, but I've not seen/heard much of it lately.Stirrup Strap Re-entry
The roll, sure works in a Sit-in kayak, but in/on a SOT its not likely you'll still be seated when you get dumped.
Another method that I've used is just hobble yourself up from front or rear, straddling the ksysk. but with all the stuff most people in todays modern kayak world pack on every square inch of surface woudl make that method ia real PITA.
The Eskomo Roll would not be possible in a SOT since it requires a person to be able to "lock" his/her lower body to the kayak by appying pressure against the inside sides of the hull from the waist down. (I took some instruction for the roll but did not stay in the class long enough to try one without assistence).
