I have included three pictures in my gallery showing what I have done to secure the front bimini. They show the tie-down/docking ropes, the velco strips (red) holding two struts together, the black straps wrapped around the boot, and the whole thing in the down position.
"ericscher" is probably right - some ratcheting straps could replace the rope and if they were real long, they could replace the black strap.
The situation was that I used what I had on hand as the various issues arose.
When I picked it up from the dealer, they had one tie-down rope installed and recommended I use it when trailering - I just added another rope and now both also serve as docking ropes when needed.
The black strap wrapped around the boot is only attached to the bimini - the structure can be raised or lowered without removing it. The problem was that this boot was the same size as the rear bimini boot, however the rear boot is taunt when installed because it is covering more material. The front boot covers less material and is much looser fitting and therefore flapped a lot when trailering.
The red velcro straps just secure the two long struts together; before, when trailering, the middle strut was only secured at one end and the other end also "flapped" around when trailering.
(would have inserted pics in this post if I wasn't maxed out from previous posts - need to go back a delete or minimize some earlier pics I guess)
