One variable on the trip time is the number of locks , entering them without having to wait for eastbound boats and even asking the lock master to call ahead to the next lock . We did that near the end of last August and saved a lot of time as you can wait a half hour for one to open, then a 25 minutes to a half hour to get in.and out..We went through a ton of them,a lot more than you will . Most were open and waiting for us bc of the call ahead. There will be long sections where you can get on plane with no worries, example ,right after you go through Lockport it's a solid wall on each side for 4.miles or so with absolutely no.houses or docks to be seen. After that there are a few short sections,then your into a populated area and water police, no wake at that point until you hit the Niagara.
