Thanks for the feedback. We have appropriate running lights
and a good spotlight so that combined with the lights
in the canal shouldn't be a problem. I have no problem sailing at night but this isn't sailing and I have never been through the canal so yes, that experience is unfamiliar. Of particular concern is the wake thrown by large boats in tight quarters. I'm not worried about either side it is just getting through the canal. Once through we'll probably drop the hook in the Bohemia River to sleep. Judging by the comments I guess it isn't rediculously tight and I hope wakes and currents are not too bad?
