I have a concern about transporting my Mirage Tandem. I have a Yakima rack system with Mako saddles, Hulleyrollers and bow/stern tie-downs, although this question probably applies to other systems. When I cinch the kayak down tight (so that it won't shift at freeway speeds), the bottom dents in. If I lessen the straps so that it won't dent, the kayak tries to turn sideways (as much as the tie-downs will allow). I have tried putting neoprene pads to spread the impact, which helps but is not a complete solution.
My concern is the the kayak will eventually be permanently dented from transporting it (this is one of the issues with roto-milled plastics). I have only had the kayak for a month but already the bottom is taking on a roller-coaster shape and is no longer gently curved. Is there a better way to carry it? Is it better to transport it upside down (with the rails carrying the weight)?
I am open to suggestions.
