get up early
as always, if you get in the river early to beat the afternoon wind...
Though that said, one year we had a no wind afternoon but decided to camp early as we still had one more day. Wind came up that night and blew all next day!! Still not that bad. As we get older, we now take one boat with motor, and tie them all together to get through the frog water. I have floated it many times without a motor in my younger days!
