These provide safe, out-of-the-way stowage for my spinnaker pole, as might be expected.
One issue is that I have to fix the forward holder on a rail that is at an angle. The consequence is that I cannot clip the pole onto the little straight chord in the holder. It still works but perhaps not quite as intended.
Pic attached. Looking at it I wonder if I might be able to turn the holder to fit. I will try again.
