Chicky gets an optimistic drive by grade of 6. The ice cycle grade is closer to 2.5, possibly sailable but not likely much fun with much fine shell ice and crunchy stuff to slow down the sailor and make down wind starts impossible. Numerous bumpy areas, few smooth ones. Old drifts only a couple of inches high and mostly hard although white. Rare patches of old black ice look like open holes but all examined had many inches of ice.
Lower ice Grades: 0. Not good for anything, difficult walking. Such as snow. 1. Not good for much 2. Ridable on ice bike, not much fun.
3. Ridable, enjoyable following nicer ice. Sailable, not much fun.
4. Sailable, might be worth doing if desparate.
5. Sailable, might be fun in larger comfy boats. 6. Sailable, tolerable in DN.
