Trent Severn worth a trip
I have been through the Trent Severn twice. The last time was my 'circumnavigation' in a 32' sail boat from Kincardine on Lake Huron through Lake St. Clair, Detroit River, Lake Erie, Welland Canal, Lake Ontario, Trent Severn, Georgian Bay and back to Kincardine. It was a great trip and for the family the Trent Severn was one of the highlights.The main concern as already mentioned is that you want to draw less than 5' - do you have the shoal draft version of the 35? In order to assure headroom in the cockpit, I made mast supports from plywood and 2x4s and clamped them to the pulpits with U bolts and used ropes amidships to provide stability. The length of the mast wasn't a problem although you will have 10' more than I did and you do have to find a dock space that long. The mast should be no problem in the locks. The marine railway was great fun - they know how to handle sail boats.With the C35, you will have absolutely no problem with Lake Simcoe or the little bit of water where you come out at the Georgian Bay end. The first time we went through we did it in a 14' outboard runabout that I had made while in high school and we didn't have a problem with that water. We enjoyed the Trent Severn - tieing up at the locks was in General not a problem for our 32 footer except at very popular locations, anchoring is possible and the scenery is nice as you pass through a lot of Ontario vacationland areas. When you come out at Midland you then have the 30,000 Islands to cruise on your way to the North Channel and it is a great area to cruise.Having said all that, this year I will be taking my new C36 from Toronto to Kincardine on Lake Huron via Lake Erie etc. The reason I am doing it that way is that it does take perhaps 1/2 a day at both ends to deal with the mast, fold and store the sails. lines, spreaders, set up the supports etc. and it is further through Georgian Bay around to Kincardine via the Trent (and I have done the Trent Severn twice).Your main challenge will be your draft and make sure you have up to date charts so that you know where the channel is. we kept an eagle eye on the buoy numbers and always knew where we were going next.
