When I'm not out sailing, I leave my TI directly on my SUT-350-S
Trailex Trailer and have done so now for a year and a half. I'm not seeing any deformation in my hull because the TI is supported on three Hobie saddles that sit directly on top of the three Trailex Crossbars. This is the main reason why I chose this trailer.viewtopic.php?f=69&t=35469
On the second page of that post I included the necessary measurements to accomplish this. Note the distances between my Crossbars are from center to center and the saddles sit directly on top of them. This can be done on a SUT-350-S
trailer (including a stern roller) because a SUT-350-S
is 18' 6" long. The SUT-350-AIT
trailer is 4' shorter and doesn't allow for this arrangement.
In my opinion, if your going to store a TI right side up on a trailer for long periods of time, it's going to need at least three points of support; weather it's a saddle or anything else:
One under the forward mirage drive well area.
One under the rear mirage drive well area and one more towards the back to assist in launching and retrieval. The stern roller I added just makes this process that much easier to accomplish.
I believe you're seeing your hull deform because you don't have enough support in the right places. It's not the fault of the saddles. The good news is that once you do support the boat properly the hull should come back to it's original shape. Storing your TI upside down on the gunnels is fine just inconvenient. I remember reading a post about someone doing this in their garage with a lift as well, try doing a search. Good luck.
