coastal vs offshore
for your type of sailing i would go with a smaller headsail lets say a 125.
so you can reef down and still have a good sail shape.If you are sailin a 30 footer i would go even smaller. For steady 25-30 knots i would also look into a radial cut sail.
offshore sails are usually smaller and of heavier cloth. the problem with a light air (big) sail is that the shape sucks when you reef down to 100%. I sail offshore and have worn out my current 135-140 in 4 years 20,000 miles. The wear was caused by too much wind.
i am having a heavier sail 6 oz cloth 110 and yankee cut.
