Review: Work Perfectly, But Only After Some Simple Modifications From The Recommended Installation In My Situation - We moor our 47' sailboat in a creek with 8' tides and can't tie directly to pilings. The TideMinders, as shipped and installed per the instructions, did not work at all with my boat on my dock. They tended to bind on the pilings as the tide changed and dragged the bow down before jumping loose, especially with a constant load and no wave action to periodically release tension. However, with some simple and cheap modifications, they work perfectly. First, install a spreader bar to hold the lines leading from the balls to the boat at the same width as the piling. This keeps the lines from pulling the balls tght against the piling under load. I used a treated 2x2 about 18" long, with holes spaced at 15" to pass the lines. On top of the spreader I mounted a 15" section of 2" PVC pipe, capped at each end to act as a float. This floats the balls, lines, and spreader up on rising tides, and provides some weight to drop everything on a falling tide. Prior to these mods, the TideMinders constantly bound up, and after the mods thay never bound up. It's simple, inexpensive, quick, effective, and preferable to extremely expensive stainless steel sliders.
Review: Work Great, Use a Double Figure 8 as a Stronger Knot - Works great for the piling dock lines. The boat now stays centered in the slip. The other 2 dock lines are on dock cleats, and long spring lines are still tied on the pilings. Bought 3 sets of 9 between 2 large pilings. This is a 41' ketch sailboat with 5/8" dock lines. Using the double figure 8 is a stronger knot than a bowline.

## Questions & Answers

**Q: I have a floating pwc dock that I'm trying to secure to 4 pilings that will move with the tides, but provide enough give/tension. Thoughts?**
A: I use my tideminder balls on a stern line from a 25 ft boat that has to ride up and down with the tide on a polyethylene-covered timber pile.  They work very well for me and I suspect they would work well for your purpose.  My one change from the instructions was to buy an extra set and add 3 to 4 more balls to the 9 ball set to get better coverage around the pile.

**Q: Will these work as well as tide slides? my boat will be near the mouth of the bay and can get very rough.  will these be able to move rapidly up/down?**
A: I use 3 different sets on three piers on my port side.  I tie up regular to starboard dock side.  The tide minders have done a wonderful job of sliding up and down the piers during normal 1-2 foot tide changes.  But have also done the job during 6-8 foot tides during some of our nor'easters last year.

**Q: How many are in a package?**
A: There are 9 to a package.

**Q: If these don't float how do you install on a dock's piling below the dock height, since they will fall into the water?**
A: They float.

### ⭐⭐⭐⭐⭐ Excellent product with great customer service.
*by R***J on April 13, 2025*

This is a great product that will save your boat in stormy conditions - especially if you are on a fixed dock. Take the time to rig your Tideminder correctly and it will be the best investment you ever made in your boat's safety. I recently ordered four boxes of nine balls each, to replace some balls that had been in service for many years. One of the boxes was missing a ball. I only got eight balls in one box instead of nine. I contacted customer service and had the missing ball in my hands two days later. Great customer service and a top notch product that won't let you down.
