I've read several times that a yak should be stored on its side, as the sides are the stronger/thickest part of the hull and this will prevent bowing or caving in. How is up to the owner, but either J hooks, or however. I use a rachet type hoist system with 2" wide web belts that have not done any damage to my Ride 115 in this position hanging over my truck for 18 mos. I tried J hooks on the wall, but it was a pain to me, and took up too much room in the garage IMO, so I use the hoist system and it hangs from the ceiling and over my truck.
Could you install J hooks on the trailer, and then just store and transport in that way ??
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
