A dinghy dry suit might work very well for you. I would look around and ask around, see what others have chosen and ask them why, whether it is just cost or there are specific reasons for what they've chosen.
One thing you can be sure of, a good knit "navy" watch cap will be good. Keeps your head a bit warmer even when wet, especially if you get a decent tightly knit wool one.
