If you're coming to the hump, it might be worth your while to try and target a musky or two while you're at it. I caught my personal best just west of the hump early last August. 53 3/4 inch and 37.25lbs. She's in my avatar. Though the size may be larger elsewhere...ie GBay, Ottawa or the St. Lawrence Rivers, you will be hard pressed to find a healthier natural Musky fishery than LSC. The regulars have ensured it's virtually 100% catch and release.
Regarding the lake itself, you should be OK with a boat that size on the hump. I've seen folks in smaller, but always felt they were taking more of a chance than I'd be prepared to out there. The hump is a lot further out from the marina than it looks! However I'd strongly recommend you listen to or bring a marine weather radio and keep a constant look to the western horizon for thunder boomers forming at this time of year.
LSC averages 11 feet deep. Typical depths around the hump vary from 11-15 feet. I've witnessed that lake go from calm conditions to four - five footers in less than an hour of steady westerly winds... and drop back to calm almost as quickly.
Unlike Simcoe, which is fairly deep....think of LSC as the world's largest puddle, picture a kid splashing in it and presto, you have a good perspective of a very windy day out there. When it's relatively calm, it is simply beautiful.
By the way, it is not uncommon to have a nice walleye hit 6-8 inch musky lures trolling at over 4 mph on LSC. I caught a beautiful 4-5 lb one a while back.
As long as you respect the lake and keep your eyes open you should be fine! Enjoy and be sure to post your conquests!!!
