At Chew, I found a good place to keep warm was kneeling on the board sheltering behind the hull whilst Joe was swimming around at the time in a good wetsuit but 1 size too large for him. The only comment i can make, as a caring father is, when i was his age i didnt even have a wetsuit and my dad still made me swim about when he was kneeling, sheltering on the centerboard...it was tough in them days, when I were a lad! We usually finished the race as well. I must be getting soft.
Anyway if it fits properly it probably will be warmer, but how do they gauge what you are wearing under the drysuit?
Semi Dry Steamers work for me as the windsurfing kitesurf stuff with the thermal surf stuff under them especially with harness and buoyancy to add further cold barriers.
