no, not on tidal water. and I have pretty good protection from wave action as well in my spot. the water level does fluctuate throughout the year by about 12-14". But even at high water, the stern of the boat would be around 6-8" inches out of the water. the bow would be at least 15 to 20" out is my guess.
I left some length on the poles and the brackets are easy to adjust the height of the entire ramp. If I raise it too much, it will be difficult to pull the boat up onto that first crossbar and get it started up the ramp.
As it is now, at high water in the spring, it would take a really jack A__ to create a wake big enough to knock the boat up off the ramp.
and I'm the only one like that on my lake
the whole ramp cost approx $350. but I got the 2" pipe for free.
I don't see how I could have made it any cheaper. the materials add up quickly.
In the end, it keeps the boat out of the water, but is so easy to use that I will get more use out of it vs. keeping it on the trailer.
