thumbs down to any launch that makes you PAY for launch only
Sunset makes you PAY and you have to run to your fishing spots...as well a longer tow to get to.
Sewells is BS as low tide is impossible to launch a good size boat from, and they charge you for launch and parking...
Ambleside is BAD in wind or low tide...parking may be full.
Kits/Vanier Park/Planetarium is better, free to launch, tow your trailer up to the planetarium lot and you could escape the parking fees. But be careful for low tides...and if you're going to back onto the sand, for crying out loud....make sure you know what you're doing...4 WD may be mandatory depending on your vehicle and trailer. Offer you options of fishing Pt. Grey, Ambleside, Atkinson, and Bowen. As it gives you the options to fish those places you can also size up the fleet and see if there are fish there, generally, if there's a few boats..there is likely some fish being pulled out of there. Also, you're more likely to meet anglers and see how successful they were.
Just my 2 cents worth.
