Reference 6K (in late January) and water temp
Hey Magda and Dale, this is a goofy follow-up to your brief conversation I overheard where Dale feigns mock concern that we'll never be able to match our reference 6K due to such favorable rowing conditions. Well, I got to thinking about it and, while I agree last Friday (1/26) had exceptional conditions, it probably did not represent the fastest conditions we'll encounter on the 6k sushi course. In particular I was thinking about water temp, the cold temp of last Friday versus the warmer temps we see at the beginning of sushi. Plus there are other considerations like eastbound head-currents from rain runoff and actually-not-that-great wind. All contribute to slower than the fastest conditions.
