Andy,
I missed your earlier question of what we were wearing. Naturally, all were in drysuits. I'm fairly certain, all, if not the majority, were clad in balaclavas with helmets as an extra layer. At the outset rockplay down the coast to Rye was an option, but as the route shows we opted for circumnav of New Castle and Pierce. But, now that I think of it, the helmet is definitely an effective windstop. Some wore pogies, some simply gloves. A conversation throughout the paddle was the pros and cons of pogies.
I once again opted for my Kokatat one piece polartec layer over a Columbia reflective primary wicking layer and a midweight Kokatat midlayer. I tried out my new NRS Maxim gloves. They use 3mm in key places and 2mm in others and are fleece-lined. They are now my go to gloves. For shoes I went with my winter approach to footwear. I purchased the NRS ATB boot in a full size larger than I normally wear. It allows me to wear a silk liner and a thicker smartwool sock. By going with the size larger and the ATB sole compression/restricting circulation and conduction are greatly minimized. The ATB has a very thick sole. Anyway, I was comfortable from head to toe. I wet-burped my drysuit at launch and lunch and then completed three very quick rolls near the takeout. Both the burping and rolls were surreal. I had no sense of cold-other than the small exposed circle of my face.
