The straight A's for Meteorological lessons at Nautical Collage plus 30 years of interpreting weather maps paid off.

Frontal passage at 16:00 followed by a wind shift and increase.

Rigging at 15;45 with 10 knots and hitting the water 15 min later with 25 knots.

Within one hour from the top of the Gotthart pass in Switzerland  to the water in Holland, haha

Sweet.
