I am just back from bobbing around on a little boat in the Irish Sea for 2 weeks, moving from marina to anchorage in a partnership of wind and sail. As in any relationship you have to be aware of external factors to keep the momentum and to move in harmony from place to place. Inevitably this means that you don’t always go when or to where or you planned and the itinerary changes according to sea and weather conditions. “Wind variable South to South West 5 or 6, 3 to 4 later; sea state moderate or rough; visibility poor,” becomes your staple diet and it is important to be ready to adapt and change course accordingly. If you don’t at best you’ll be miserable and at worst your boat will surely founder.
