In 30kt+ winds on Thursday morning the tide was a bit too high for smooth water, but let you get into the whole NM run. In the arvo the water level had dropped and water was smoother and weed more on the surface. This weed is highly abrasive, and chews up the leading edge of G10 or carbon fins, whereas a fangy aluminium one just gets polished.
So 0.7 is just a tad high 0.5 would be close to ideal On Wednesday we got out about 12:30 and it was a tad low.
In lighter winds, the chop isn't as pronounced, so deeper water would still be a flat sail
