A 37' Crealock from Florida to Puerto Rico. Spent 11 days. 7 of them at sea. 3 in the trade winds. 15 knot wind and 15' seas. This felt the same. It started as a nice day. Ended with 20+mph wind. At least it was at my back. That's a first. 4hrs of heavy wind is all I could take.
Start to a nice day.
The wind at my back and miles of flat water.
Starts to build.
Just keeps coming.
After 4hrs of 20+ mph wind I had enough. I headed in and made camp.
