Re: NO PFDs
Its funny, I never thought about drysuits and was unaware of float suits or immersion suits. Thank you everyone for bringing those to my attention.
On the subject of inflatables in cold weather, I decided to do some additional research about the subject and called Mustang (who made my most recent set of hydrostatic Type 5's.). I spoke with a tech. rep. who said that there was definitely a temperature at which their inflatables will not function properly. Mustang is currently doing testing to determine what that temperature actually is but the person suggested that it is lower than freezing temps.
Mustang sent me the following statement in an email;
"Please note that cold weather adversely affects the operation of PFDs. While the CO2 cartridge will fully inflate your vest most of the year, in extremely cold temperatures the same amount of gas will not expand to the same volume, reducing the vestís buoyancy. We recommend using a foam vest in these conditions."
Based on the conversation with the Mustang rep., it was clear that while a literal temperature of 32 F would not cause an inflatable to fail to fully inflate, there definitely is a temperature where using an inflatable is discouraged.
But as long as i am in crow eating mode, I also realized that I have a rule that I don't go out sailing if the temps are below 38-40 F or so since I am concerned with icing on the decks if the temps drop. I hindsight it occurred to me that would certainly color my view of things.
