Boat ride

The ice in the picture was 11" when I picked it up some melted by time we took picture. I got this piece 75 yards short of Green Bouy #G5. The boat would just ride up onto ice and sit there,the Harbercraft has a very square stern took me 30 min to get turned around. This is the furthest I have ever made it on first attempt.checking back in diarys by time I get to this point we have boated to BarePoint anywhere between 5-14 days.very hard to predict when we may be boating due to cold overnight temps. Last night we made 3/8" the wind/sun took care of that on large body of open water but around docks just melting now at 14:00. My first prediction was May 05 ,guessing anywhere between 1st to 5 th ??
