I'm doing a wrecktrip in the red sea in Jan 2008. Depths will be around 40-90m and divetime around 2-3h. Watertemp is around 20-21C (68-70 Fahrenheit) and I am thinking of wearing a 7mm semidry. Before doing this I thought I'll check with the members here if this is doable without freezing my balls off. Drysuit is of course an option but at the moment my old drysuit doesn't have a pee-valve and is no longer dry (I will replace my drysuit but will not get a new one in time for my trip).
I have too little experience of wet dives so any help / advice is appreciated.
EDIT: added temp in Fahrenheit

I've done it.
the problem is only when you're not moving in the deco, if dry is not an option than plan on continually swimming slowly in the deco and you should be fine if you have a good suit (and gloves...)
