Wanderingstar has good advice about wool. Avoid cotton (a.k.a. "killer cotten" to winter sports enthusiasts) since it loses 98% of it's insulation when it's wet -- when you really need it, it becomes almost useless. Spun polyester (a.k.a. fleece) and wool are best. If you get splashed a bit on the foredeck it will matter a whole lot less.
I like to be tied onto the boat, whenever I'm outside of swimming distance of land. If that's what you do, remember that you simply can't swim as far in cold water.
A thermos of hot liquid is a real pleasure on a cold day.
Have a great trip. Post pictures later!
[Edit: Didn't see Tom's post before I got this one posted. He'll probably have some great advice.]
Great minds discuss ideas;
Average minds discuss events;
Small minds discuss people.
The best minds discuss sailing.
