What brand of jacket do you have IT? The requirement from our cat 3 inspector was in accordance with the manufacturers instructions. We have a range, some that specify self service, some that specify service by an agent, and some that don't seem to specify anything.
SSANZ this year were quite specific at their briefing that you must have your jackets serviced in accordance with the manufacturers requirements and they will be spot checking and throwing out boats that haven't. I ended up buying a new jacket as the cost was comparable to having my baltic serviced. I've self checked the baltic recently (and done thousands of offshore miles in it this year and still prefer to wear it) but the messaging from SSANZ was that it must be done in accordance with manufacturers requirements.
Have a read of the instructions from Baltic where they outline below, http://www.baltic.se...flatable_en.pdf "
