Well I used the west ramp for the first time yesterday. It was not right at low tide, so I can't really comment on how doable it is on a low. Seemed ok for launching, but pulling out might be a horror show. As of now I'd say the ramp is fairly usable but how long it will stay that way is anyone's guess. They've only put cinder blocks and gravel at the lower tide sections of this ramp as you can see in the posted pictures. The gravel has already started to wash out from between the blocks. How long do they really think these blocks and gravel are going to remain in place. As soon as we hit the stormy season I'd guess all this stuff is going to be half washed away and the blocks will all be Topsy turvy (if not washed completely out of place). I've never seen a ramp constructed like this anywhere, let alone in a major city. It's like something you'd expect to see at an unmaintained govt rec site, not one of the largest cities in Canada.
For now I'd say it's usable. How long it stays that way is the question. Once these blocks get all covered in algae I don't imagine they will afford much traction. But they'll probably just end up washing away anyways after a while. I think I did a better job of building a ramp on our property when I was 12 years old hauling rocks and gravel in a wheel barrow. Bit of a joke for a city this size in this day and age.
