Quick and easy help for your stretched out Bimini top
 

I thought that I would pass on a trick to breath new life in to your stretched out Bimini top, it is cheap and easy to do.......

Tops usually stretch with time and end up getting sloppy... Likely you have already tried shortening the 4 corner attachment points to stretch it open more which helped some but did not cure it.

Get a length of flexible spa hose the length of the pocket(s) that the bow(s) slides into the pocket and use it as a shim. Spa hose is cheap and easy to find at hardware or hot tub stores. If this trick did not cure the problem you may need to shorten the attachment points on the corner attachments as well.
