The wind and seas have increased so we are proceeding with only the little Yankee up. We are seeing gusts well into the 30's. The seas are a constant 10-12 feet with an occasional 15 footer. Not entirely sure how big they were since we have never seen 15 footers but we had to look way up to see the top. Luckily, we were crossing them at an angle so it was a fairly gentle ride up and over. Only occasionally would we drop off the back and go WHAM into the bottom of the wave.
