Stephane99, did you get to the Toronto Boat Show, all the marinas were there.
Do you have the Ports book yet? Ports Cruising Guides
If not get it now. West Marine, Mason's etc. will have them. Do you have one yet????? It lists all the marinas, facilities, etc. for all of Georgian Bay. It also gives you all the anchorages for all of Georgian Bay. Invaluable that you don't have to guess where and how to anchor and which areas you can get to shore with the dog while you're out..... very important !!!!
Our favorite anchorage is Beckwith, Hope and Christian Islands. It's a 4-6 hour sail / motor great anchorage, you can take the dog to shore on the beaches, and clear blue water with sandy bottom. Just watch the forecasted wind direction for overnight. I've been caught a couple of times with a bouncy sleep after a bad call on wind.
Otherwise, Beausoliel Island is a National Park, so can go to shore, but are supposed to pay a landing fee, which they are cracking down on a bit more. But lots of protected anchoring and beautiful scenery, although can be busy.
Beyond that.... get the Ports book, there's lots and lots of options. I could go on for hours on all the places.
Also you can check out all the marinas online. Google their names. This is a good overview of the marinas int he area..... Marinas.com
Watch for the rates. Some marinas I found were pricing haul-out and launch separate from the docking fees.
& Beacon Bay
, may be a little shallow for your deep draft. Heard of a couple of boats with issues last year.
We're at BayMoorings
, deep water, we're in 10 - 12 ft., reasonably priced and I find it's closer to getting "out there" than the other marinas in Midland.
. Deep water, next to BayMoorings. Doesn't have the marina facilities, i.e. pool etc. but is less expensive.
Bay Port & Wye Heritage, both deep water, mix of Power and sail, more expensive, lots of marina facilities, further to getting " out there"
Midland Bay Sailing Club, less expensive but you have to do volunteer hours otherwise pay a higher fee. Use a crane for haul-out so mast has to come down every year. Only have 1-2 days for haul-out or launching, other marinas with travel-lift you pick your day and keep your mast up.
Victoria Harbour, don't know much, but worth checking out. I believe similar pricing to Penetang, but again further.
