I told you I didn't like Block. And now I have one more strike against floating docks ... when they start to move they seem to oscillate at a different rate than the boats. During Wilma you could see the floating dock snapping against the dock lines and the lines just blowing apart ... but if a boat and the dock were in sync ... say on one side of the main floating dock and out of sync on the other ...that could be a heavy shock on the pilings. I ended up with my boat and a finger pier still nicely tied on .. but the finger pier completely broken off the main dock ... and the only thing left was the one bow line I had attached to the main dock cleat. no damage to the boat ... duh.
I think if you can find a roll of the PVC tape used for shrink wrap it will be better than standard duct tape ... afterall it generally lasts all winter.
Also there is a heavy duty duct tape that also is available. problem with both is that the surface has to be dry.
Hope you get fair wind to spin back home. Has been foggy in NPT most of this weekend and at least 10 degrees colder than inland.
