The rule says the sailor must be able to right the boat but this includes using any dependable righting aid you can think off.
(1.8) states;
1.8.1 It is the responsibility of the crew to ensure that the boat is equipped with a righting system that will enable the crew to right the boat without outside assistance.
My F16 is equipped with a righting line but still occasionally I can't right my F16 when the wind is very light. So by the letter of the law I'm breaking a F16 Rule!
