Hi Sofia, welcome, this is my first post so thought I would share. I keep my boat @Ease at Meinke Marina and have sailed all over the west side of Erie. As for St Clair, Miller Marina is nice cheap
place and I have a 5'3" draft
and had no issues. It's kind of run down but in a pinch worked great, we hugged the coast coming down so no freighter issues from us. Just give them room. As far as going down the Detroit, that was fun. Cool to see Canada
and Detroit. There was some rock concert so we got free entertainment as we passed Dertoit last year. One thing is you can come and go across the border as long as you don't stop. Once you stop then if in Canada
need to check in. Have fun and if you see @Ease floating around, give a shout out.
