We are very happy with the EZ rack for 2 Kayaks installed with the over water mounting.
We also need the expansion posts to reach the interior joists on our dock. This was a very quick and easily accomplished modification. The over water mounting is stable, secure, and out of the way. A very effective method of storing our kayaks close to where we launch and enjoy them.
