The Golden Rule: Never go out farther than you want to swim in.
It takes a fairly talented kiter to rescue someone.
If other riders are unfamiliar with your gear they usually will not know how to assist you.
For example, I still can not figure out how to drag in one of those Naish terradactyl Shapes.
If you have to swim it is good excercise.
If someone assists you Bonus, Buy them some beer, They deserve it...
Aloha, Ride Safe, have Fun...
