mlaver, I understand your worry but I think, as in most things about boats, the answer is it depends. I have Garhauer racks that I have used for 5 or 6 years so far. My boat
is a bit bigger and the topsides are a bit higher than yours but for costal cruising, short hops offshore
in settled weather
Iíve never had a concern with solid water
doing damage to the racks or the stanchions. For longer trips offshore
or if the weather
is iffy I remove the kayak or the SUPs from the rack. Similarly, I often tow my air floor inflatable dinghy
but when preparing for offshore or longer costal trips I bring it aboard and deflate it.
