Anyone try the hot wine apres dive?
Other advice relating diving wet in cold:
I vote hooded vest. Don't bother with buying just a hood. The cost diff is only ~$30. With just a hood, cold water RUNS DOWN YOUR BACK. Not very pleasant at 30ft. Even worse at 60ft when you begin shivering.
I think it goes without saying that you need to put on the wet suit right in the first place. Don't be shy about asking your buddy to help you put on your wet suit if necessary. If the wet suit won't lay flat, a little soapy water on the wrists and leg holes can help.
I think this trick is from dry suit neoprene divers - fold the neoprene for the arm hole back into the hole under your wrist. I'm not sure if I'm describing it correctly. This will help trap water in the suit and keep you warmer.
More neoprene is better, but too much results in Mr. Penguin. My buddy wears his 7mm and his tropical 3mm shorty AND his wife's shorty. He waddles to the water and can't really turn his head. He's funny looking, but WARM.
If the air temps are freezing, metal to metal connections will FREEZE together. Wet gloves, hoods, etc can freeze to whatever you place them on - picnic benches, cars... etc. Not to mention frozen hair..
We don't have heated changing rooms at our dive sites, so some members of my dive club wear their wetsuit on the drive home. I've tried that and this really, really sucks. I find that helping my buddy change and then having him help me speeds everything up. Big thick fleece hat helps a ton too. I look funny, but I'm warm.
I haven't tried hot apple cider, but I guess the effect is the same. When I was kayaking in Maine, I got addicted to hot cranberry juice.
I guess the last is looking into buying a used dry suit. Entry level drysuits w/ fleece, boots, go for $1000. Used is about $500. As a new wetsuit is $200-300, hooded vest $100, gloves & booties $100, you might be ahead if you dispensed with the wet suit altogether.
