Type 1 is for USCG compliance by commercials. Not you. Your Type lll will keep you compliant. There are some awesome SOLAS inflatable vests being sold by Crewsaver, they supply industry and the mil. Top shelf stuff. Double carts and Type 1 performance if you want to go there. But it isn’t worth their while to USCG cert for a very small market. Commercials stow cheap Type 1 USCG compliant foam PFDs for their passenger load number. Mariners are free to equip to a higher standard and do so. SOLAS.
A belt pouch PFD type lll makes a fine dink jacket, but you have to wear it. If you have a swimmer the manual version is bone simple to maintain. Never put one on a non-swimmer. They also make a pretty good snorkle emergency float device. I used to give the belt pouch PFD to crew, but most of them upgraded to auto inflators with harnesses.
Far more important to me than the USCG cert is a +33 gram cart, hydrostatic auto inflator, and lifting rings. A spray hood too.
